Head Stud Kit.\u003c\/p\u003e\u003cp\u003eIt is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.\u003c\/p\u003e\u003cp\u003eFor openers, ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Each stud is placed vertically in special racks and precisely heat-treated to 200, 000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.\u003c\/p\u003e\u003cp\u003eFollowing heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.\u003c\/p\u003e\u003cp\u003eARP studs are thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.\u003c\/p\u003e\u003cp\u003eYou will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!\u003c\/p\u003e\u003cp\u003ePremium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import applications.\u003c\/p\u003e\u003cp\u003eYou won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality.\u003c\/p\u003e\u003cp\u003eClearly, ARP Head Stud\/Bolt Kits are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.\u003c\/p\u003e\u003cp\u003eHIGH PERFORMANCE SERIES: High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing. All High Performance Series bolts are 180, 000 psi (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.\u003c\/p\u003e\u003cp\u003ePRO SERIES: All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200, 000 psi. ARP Pro Series head bolt kits are application specific – designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP “ZERO defect – ZERO failure” quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.\u003c\/p\u003e\u003cp\u003eHead Studs vs Bolts: On many street-driven vehicles, where master cylinders and other items protrude into the engine compartment, it’s probably necessary to use head bolts so that the cylinder heads can be removed with the engine in the car.\u003c\/p\u003e\u003cp\u003eFor most applications, however, studs are recommended. And for good reason. Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment.\u003c\/p\u003e\u003cp\u003eStuds also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut.\u003c\/p\u003e\u003cp\u003eIf everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torquing, make sure studs and bolts are re-torqued after the engine has been run.\u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e12mm 12pt, 4mm Allen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFinish: Black\u003cbr\u003eMaterial: 8740 Chrome Moly\u003cbr\u003eQuantity: Kit\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003eDesigned to unlock more performance out of your vehicle\u003cbr\u003eDeliver a reasonable balance of strength and durability\u003cbr\u003ePremium construction built with unmatched quality standards\u003cbr\u003eEnsure smooth, reliable operation and long-lasting service more details on - https:\/\/www.carid.com\/arp\/pro-series-12-point-cylinder-head-stud-kit-mpn-203-4204.html\u003c\/p\u003e\u003cp\u003e\u003ca href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/203-4204.pdf%22\" target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines:Toyota 3 S GTE\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821211349300,"sku":"203-4204","price":1723.15,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_29.jpg?v=1672844026"},{"product_id":"arp-203-5404-toyota-2-0l-3sgte-main-stud-kit","title":"ARP 203-5404 Main Stud Kit for Toyota 3SGTE","description":"\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e12mm 12pt, 4mm Allen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eMaterial: 8740 Chromoly\u003cbr\u003eKit Type: Stud\u003cbr\u003eMain Bolt Style: 2-Bolt\u003cbr\u003eFinish: Black\u003cbr\u003eQuantity: Kit\u003c\/p\u003e\u003cp\u003e\u003ca href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/203-5404.pdf%22\" target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821211414836,"sku":"203-5404","price":1171.17,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_272.jpg?v=1672844035"},{"product_id":"arp-260-4701-subaru-ej2-0l-2-5l-dohc-head-stud-kit","title":"ARP 260-4701 Head Stud Kit for Subaru EJ2.0L \u0026 2.5L DOHC","description":"\u003cp\u003ePro Series 12 Point Undercut Cylinder Head Stud Kit by ARP®.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability.

Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.\u003c\/li\u003e\n\u003cli\u003eCUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field.

Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration.

Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications.

ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods.

It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor.

Simply stated, there’s not a better stud setup on the market today.\u003c\/p\u003e\u003cp\u003eFor openers, ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Each stud is placed vertically in special racks and precisely heat-treated to 200, 000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.\u003c\/p\u003e\u003cp\u003eFollowing heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.\u003c\/p\u003e\u003cp\u003eARP studs are thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.\u003c\/p\u003e\u003cp\u003eYou will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!\u003c\/p\u003e\u003cp\u003ePremium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import applications.\u003c\/p\u003e\u003cp\u003eYou won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality.\u003c\/p\u003e\u003cp\u003eClearly, ARP Head Stud\/Bolt Kits are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.\u003c\/p\u003e\u003cp\u003eHIGH PERFORMANCE SERIES: High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing. All High Performance Series bolts are 180, 000 psi (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.\u003c\/p\u003e\u003cp\u003ePRO SERIES: All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200, 000 psi. ARP Pro Series head bolt kits are application specific – designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP “ZERO defect – ZERO failure” quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.\u003c\/p\u003e\u003cp\u003eHead Studs vs Bolts: On many street-driven vehicles, where master cylinders and other items protrude into the engine compartment, it’s probably necessary to use head bolts so that the cylinder heads can be removed with the engine in the car.\u003c\/p\u003e\u003cp\u003eFor most applications, however, studs are recommended. And for good reason. Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment.\u003c\/p\u003e\u003cp\u003eStuds also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut.\u003c\/p\u003e\u003cp\u003eIf everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torquing, make sure studs and bolts are re-torqued after the engine has been run.\u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e9\/16 12pt, 4mm Allen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eFinish: Black\u003cbr\u003eMaterial: ARP2000\u003cbr\u003eQuantity: Kit\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003eDesigned to unlock more performance out of your vehicle\u003cbr\u003eDeliver a reasonable balance of strength and durability\u003cbr\u003ePremium construction built with unmatched quality standards\u003cbr\u003eEnsure smooth, reliable operation and long-lasting service \u003c\/p\u003e\u003cp\u003e\u003ca data-tabindex-counter='\"1\"' data-tabindex-value='\"none\"' href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/260-4702.pdf%22\" tabindex='\"-1\"' target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines: Subaru 1.8L-2.5L SOHC EJ Series\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821213282612,"sku":"260-4702","price":2772.77,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_14.jpg?v=1672846014"},{"product_id":"arp-260-6301-subaru-ej-series-press-fit-rod-bolt-kit","title":"ARP 260-6301 Rod Bolt Kit for Subaru EJ18 1.8L \u0026 EJ22 2.2L SOHC.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability. Make the most of your racing budget and rely on ARP rod bolts. You’ll find the ARP name proudly stamped on each bolt as your assurance of quality.\u003c\/p\u003e\u003cp\u003eFeatures:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eForged in-house at ARP using only the finest quality materials\u003c\/li\u003e\n\u003cli\u003eHeat-treated using special vertical racks to assure complete 360° penetration\u003c\/li\u003e\n\u003cli\u003eThreads rolled after heat-treat to provide up to 10-times longer fatigue strength\u003c\/li\u003e\n\u003cli\u003ePrecision CNC-machined to exacting specifications\u003c\/li\u003e\n\u003cli\u003eSpecially designed for optimum reliability in each application\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWave-Loc Features:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWave-Loc surface contacts the rod and cap for optimum alignment and reduction of fluctuating stress – which strengthens the rod itself!\u003c\/li\u003e\n\u003cli\u003eProvides snug fit for all OEM connecting rods (interference range of .001? to .005?), despite wide range of factory rod bolt hole tolerances.\u003c\/li\u003e\n\u003cli\u003eAvailable for most applications.\u003c\/li\u003e\n\u003cli\u003eSuperior material grain flow because of patented Wave-Loc surface design as compared to knurled bolts that have sharp edges and “built-in” stress risers.\u003c\/li\u003e\n\u003cli\u003eGalling and scoring of the rod is virtually eliminated because there is only smooth contact and absolutely no “digging.”\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eMaterials Used In ARP Connecting Rod Bolts:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e8740 CHROME MOLY: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.\u003c\/li\u003e\n\u003cli\u003eCUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260, 000-280, 000 psi.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e11mm 12pt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFastener Style: Bolt\u003cbr\u003eFinish: Polished\u003cbr\u003eMaterial: ARP 2000\u003cbr\u003eQuantity: Set of 8\u003cbr\u003eStretch: 0.0070\"-0.0075\"\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003ePerfect for upgrading your fuel injection system\u003cbr\u003eMade with the use of the highest quality materials\u003cbr\u003eModern technology for uncompromising reliability\u003cbr\u003eProven to deliver unmatched performance and strength\u003cbr\u003eWill provide dependable operation for years to come \u003c\/p\u003e\u003cp\u003e\u003ca data-tabindex-counter='\"1\"' data-tabindex-value='\"none\"' href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/260-6301.pdf%22\" tabindex='\"-1\"' target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines: EJ18 1.8L \u0026amp; EJ22 2.2L SOHC, EJ25 2.5L, SOHC\/DOHC, non-turbo \u0026amp; EJ20 2.0L DOHC turbo\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821213315380,"sku":"260-6301","price":1258.4,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/260-6301.jpg?v=1672846021"},{"product_id":"arp-203-5402-toyota-7mgte-supra-2-bolt-main-stud-kit","title":"ARP 203-5402 Main Stud Kit for Toyota 7MGTE Supra 2-bolt","description":"\u003cp\u003eThere are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block.

All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.\u003c\/p\u003e\u003cp\u003eHead Studs vs Bolts: On many street-driven vehicles, where master cylinders and other items protrude into the engine compartment, it’s probably necessary to use head bolts so that the cylinder heads can be removed with the engine in the car.\u003c\/p\u003e\u003cp\u003eFor most applications, however, studs are recommended. And for good reason. Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment.\u003c\/p\u003e\u003cp\u003eStuds also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut.\u003c\/p\u003e\u003cp\u003eIf everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torquing, make sure studs and bolts are re-torqued after the engine has been run.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e1\/2 12pt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFinish: Black oxide\u003cbr\u003eMaterial: 8740 Chrome Moly\u003cbr\u003eQuantity: Kit\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003eDesigned to unlock more performance out of your vehicle\u003cbr\u003eDeliver a reasonable balance of strength and durability\u003cbr\u003ePremium construction built with unmatched quality standards\u003cbr\u003eEnsure smooth, reliable operation and long-lasting service.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/203-3902.pdf%22\" target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines:Toyota 7MGTE \u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821213511988,"sku":"203-3902","price":1289.86,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_123.jpg?v=1672846070"},{"product_id":"arp-203-3801-toyota-1-3l-4e-fe-fte-1-5l-5e-fe-fhe-4cyl-head-bolt-kit","title":"ARP 203-3801 Head Bolt Kit for Toyota 1.3L (4E-FE\/FTE \u0026 1.5L (5E-FE\/FHE) 4-cylinder","description":" \u003ctable width=\"400\" border=\"1\" cellpadding=\"6\"\u003e\u003ctbody\u003e\n\u003ctr bgcolor=\"#CCCCCC\"\u003e\u003cth colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"75%\"\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd align=\"right\"\u003e10mm tri-square, internal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e ","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821213544756,"sku":"203-3801","price":1534.39,"currency_code":"AED","in_stock":true}]},{"product_id":"arp-203-6301-toyota-1-8l-2zzge-4-cylinder-rod-bolt-kit","title":"ARP 203-6301 Rod Bolt Kit for Toyota 1.8L (2ZZGE) 4-cylinder","description":"\u003cp\u003eA large number of connecting rod manufacturers have chosen ARP bolts as standard equipment. They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability.

Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.\u003c\/li\u003e\n\u003cli\u003eCUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260, 000-280, 000 psi.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e7\/16 12pt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFastener Style: Bolt\u003cbr\u003eFinish: Natural\u003cbr\u003eMaterial: ARP 2000\u003cbr\u003eQuantity: Set of 8\u003cbr\u003eStretch: 0.0075\"-0.0080\"\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003eForged in-house at ARP using only the finest quality materials\u003cbr\u003eHeat-treated using special vertical racks to assure complete 360° penetration\u003cbr\u003eThreads rolled after heat-treat to provide up to 10-times longer fatigue strength\u003cbr\u003ePrecision CNC-machined to exacting specifications\u003cbr\u003eSpecially designed for optimum reliability in each application.\u003c\/p\u003e\u003cp\u003e\u003ca data-tabindex-counter='\"1\"' data-tabindex-value='\"none\"' href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/203-6301.pdf%22\" tabindex='\"-1\"' target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines:Toyota 1.8L (2ZZGE)\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821213577524,"sku":"203-6301","price":889.46,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/203-6301_1.jpg?v=1672846083"},{"product_id":"arp-260-4704-subaru-ej-2-0-2-5l-dohc-ca625-head-stud-kit","title":"ARP 260-4704 Head Stud Kit for Subaru EJ 2.0\/2.5L DOHC CA625+","description":" \u003cp\u003eIt is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants.

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 200, 000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.\u003c\/p\u003e\u003ctable border=\"1\" cellpadding=\"6\" style=\"width:400px\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e12mm 12pt, 4mm Allen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eMaterial: 8740 Chromoly\u003cbr\u003eKit Type: Stud\u003cbr\u003eMain Bolt Style: 2-Bolt\u003cbr\u003eFinish: Black\u003cbr\u003eQuantity: Kit\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003eDesigned and manufactured using innovative technologies\u003cbr\u003eMade with maximum safety and reliability in mind\u003cbr\u003eExpected to provide seamless service for years.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/tech.arp-bolts.com\/instructions\/203-5407.pdf\" target=\"_blank\"\u003e\u003cspan style=\"color:#3498db\"\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines:Toyota 1.8L (2ZZGE)\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e ","brand":"ARP","offers":[{"title":"Default Title","offer_id":45310995661108,"sku":"203-5407","price":1198.34,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_128.jpg?v=1672849106"},{"product_id":"arp-203-2801-toyata-3s-gte-flywheel-bolt-kit","title":"ARP 203-2801 Flywheel Bolt Kit for Toyota 3 S GTE. 8 pieces","description":" \u003ctable border=\"1\" cellpadding=\"6\" style=\"width:400px\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan=\"2\"\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e3\/4 12pt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUHL\u003c\/td\u003e\n\u003ctd\u003e1.000˝\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Size\u003c\/td\u003e\n\u003ctd\u003eM12 x 1.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFastener Style: Bolt\u003cbr\u003eFinish: Black\u003cbr\u003eMaterial: 8740 Chrome Moly\u003cbr\u003ePackage Type: Skin\u003cbr\u003eQuantity: Set of 8 \u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/tech.arp-bolts.com\/instructions\/203-2801.pdf\" target=\"_blank\"\u003e\u003cspan style=\"color:#3498db\"\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines:TOYATA 3S-GTE\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e ","brand":"ARP","offers":[{"title":"Default Title","offer_id":45311000183092,"sku":"203-2801","price":572.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/203-2801_1.jpg?v=1672849335"},{"product_id":"arp-203-2901-toyota-2-0l-4u-gse-4cyl-flexplate-bolt-kit","title":"ARP 203-2901 Flexplate Bolt Kit Toyota 2.0L 4U-GSE 4-cylinder","description":" \u003cp\u003eFlywheel and Flexplate bolts play an important role in the performance and safety of race cars and street machines alike.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability.

Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.\u003c\/li\u003e\n\u003cli\u003eCUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260, 000-280, 000 psi.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"' style='\"width:400px\"'\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth colspan='\"2\"'\u003eSpecifications\u003c\/th\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket Size(s)\u003c\/td\u003e\n\u003ctd\u003e11mm 12pt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ca data-tabindex-counter='\"1\"' data-tabindex-value='\"none\"' href=\"%22https:\/\/tech.arp-bolts.com\/instructions\/203-6302.pdf%22\" tabindex='\"-1\"' target='\"_blank\"'\u003e\u003cspan style='\"color:#3498db\"'\u003e\u003cstrong\u003eKit Instructions\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eFits Following Engines:Toyota 4U-GSE 2.0L 4-cylinder\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821216067892,"sku":"203-6302","price":826.54,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/203-6302.jpg?v=1672852862"},{"product_id":"arp-203-4207-toyota-3sgte-ca625-head-stud-kit","title":"ARP 203-4207 Head Stud Kit for Toyota 3SGTE custom age 625+","description":"\u003cp\u003eIt is for good reason that virtually every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants.

They’re proud to advertise their products as being equipped with ARP rod bolts. And for good reason. The “weak link” in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005?. Below you will find an extensive listing of aftermarket connecting rods and replacement bolt specifications.\u003c\/p\u003e\u003cp\u003eIn some instances, you may want to go to an ARP rod bolt made from a better grade of material. This will provide you with improved reliability. However, please understand that when you want bolts made from exotic, super high strength materials, the cost will increase significantly. If you’re on a budget, it’s best to go with the most cost-effective solution. This is typically defined by the loads that are carried by the bolts in terms of piston\/rod weight and the rotational speed of the engine. The most cost effective design is the one in which the bolt strength is just great enough to handle its anticipated load – plus a safety margin for the occasional overloads. Using a material which has far more strength than required is not as cost effective – but will definitely give you an extra margin of safety and longer service life.\u003c\/p\u003e\u003cp\u003eYou should also know that ARP rod bolts are superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown ARP rod bolts to have ten times the fatigue strength of other bolts. In the chart below, you’ll find a bar chart that graphically shows the difference between ARP Pro Series rod bolts and the fastener made by a leading competitor. It’s easy to see why ARP bolts are superior. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability. Make the most of your racing budget and rely on ARP rod bolts.

Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180, 000 and 210, 000 psi.\u003c\/li\u003e\n\u003cli\u003eAERMET: With a typical tensile strength of 290, 000-310, 000 psi, Aermet is a new martensitic super-alloy that is stronger and less expensive than the super-alloy austenitic materials that follow. Because it is capable of achieving incredibly high clamping loads, it is ideal for short but extreme environments like top fuel, funny car and some short track applications. Although Aermet is a maraging steel that is far superior to other high strength steels in its resistance to stress corrosion, it must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eARP2000: ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than 8740. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving a clamp load at 220, 000 psi. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.\u003c\/li\u003e\n\u003cli\u003eL19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260, 000 psi. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.\u003c\/li\u003e\n\u003cli\u003eINCONEL 718: A nickel based material that is in the high temperature, super-alloy class, it is found to be equally suitable in lower temperature applications. This material delivers tensile strengths in the 210, 000-230, 000 psi range and exhibits improved fatigue properties. Best of all, Inconel 718 is completely immune to hydrogen embrittlement and corrosion.\u003c\/li\u003e\n\u003cli\u003eARP3.5 (AMS5844): While similar to Inconel 718, these superalloys are found in many jet engine and aerospace applications where heat and stress attack the life of critical components. The high cobalt content of this alloy, while expensive, delivers a material with superior fatigue characteristics and typically tensile strength in the 260, 000-280, 000 psi range. The immunity to hydrogen embrittlement and corrosion of these materials is a significant design consideration. These materials are primarily used in connecting rods where extremely high loads, high RPM and endurance are important factors – Formula 1, NASCAR and IRL applications.\u003c\/li\u003e\n\u003cli\u003eCUSTOM AGE 625 PLUS: This newly formulated super-alloy demonstrates superior fatigue cycle life, tensile strength and toughness – with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. Typical tensile strength is 260, 000-280, 000 psi.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003ctable border='\"1\"' cellpadding='\"6\"'

every top professional engine builder relies on ARP Pro Series head studs for their all-out competition powerplants. Simply stated, there’s not a better stud setup on the market today.\u003c\/p\u003e\u003cp\u003eFor openers, ARP uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Each stud is placed vertically in special racks and precisely heat-treated to 200, 000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best.\u003c\/p\u003e\u003cp\u003eFollowing heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground – the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned – something that won’t happen with inferior quality head studs.\u003c\/p\u003e\u003cp\u003eARP studs are thread rolled after heat-treat, which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it’s tough on tooling, but the results are well worth the extra effort.\u003c\/p\u003e\u003cp\u003eYou will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the “stretch” of both studs, which makes for a more consistent clamping force – and one that compensates for head gasket compression when the cylinder heads are installed. This helps prevent blown head gaskets, and assures optimum engine sealing!\u003c\/p\u003e\u003cp\u003ePremium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import applications.\u003c\/p\u003e\u003cp\u003eYou won’t find a better quality stud on the market from any other source. Look for ARP stamped on each stud as your assurance of quality.\u003c\/p\u003e\u003cp\u003eClearly, ARP Head Stud\/Bolt Kits are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.\u003c\/p\u003e\u003cp\u003eHIGH PERFORMANCE SERIES: High Performance head bolts are available with a reduced wrenching hex or 12-point and wide area flanged head that eliminates the need for valve train removal to facilitate cylinder head retorquing. All High Performance Series bolts are 180, 000 psi (which is 15% stronger than Grade 8) and kits come complete with hardened parallel-ground washers.\u003c\/p\u003e\u003cp\u003ePRO SERIES: All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and are rated nominally at 200, 000 psi. ARP Pro Series head bolt kits are application specific – designed for use with typically competition only components. These fasteners deliver superior strength and meet the ARP “ZERO defect – ZERO failure” quality standard. Hardened and parallel-ground washers are included with each kit to ensure even load distribution and accurate torque readings. All Pro Series head bolts have a reduced wrenching hex or 12-point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing and permits the use of larger diameter valve springs. Most applications have undercut short bolts that can help eliminate head gasket failures through providing more “stretch” to compensate for the additional compression of gaskets.\u003c\/p\u003e\u003cp\u003eHead Studs vs Bolts: On many street-driven vehicles, where master cylinders and other items protrude into the engine compartment, it’s probably necessary to use head bolts so that the cylinder heads can be removed with the engine in the car.\u003c\/p\u003e\u003cp\u003eFor most applications, however, studs are recommended. And for good reason. Using studs will make it much easier to assemble an engine (especially a racing powerplant which must be serviced frequently and quickly!) with the cylinder head and gasket assured of proper alignment.\u003c\/p\u003e\u003cp\u003eStuds also provide more accurate and consistent torque loading. Here’s why. When you use bolts to secure the head, the fastener is actually being “twisted” while it’s being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A stud should be installed in a “relaxed” mode – never crank it in tightly using a jammed nut.\u003c\/p\u003e\u003cp\u003eIf everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. Remember, an undercut shorter stud will have a rate similar to a longer, standard shank stud. This provides a more even clamping force on the head. Because the head gasket will compress upon initial torquing, make sure studs and bolts are re-torqued after the engine has been run.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits Following Engines: Toyota 5.7L 3UR-FE\u003c\/strong\u003e\u003c\/p\u003e","brand":"ARP","offers":[{"title":"Default Title","offer_id":44821217542452,"sku":"203-4704","price":4174.17,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/1482\/8852\/products\/ARP4301-01NEW_86.jpg?v=1674572537"}],"url":"https:\/\/www.samperformance.com\/collections\/bolts-and-studs.oembed?page=2","provider":"SAM Performance","version":"1.0","type":"link"}
