ARP Connecting Rod Bolt Kit for evo 8, 9
Our Price: $40.00

ARP manufactures replacement rod bolts for many popular import and domestic Sport Compact engines that are made of premium grade 8740 chrome moly steel and heat treated to a nominal tensile strength of 200,000 psi. Threads are rolled after heat treat to ensure optimum fatigue strength. They are far superior to OEM fasteners in terms of durability and service life – fully capable of handling the extra stress of high combustion pressure engines.

For extreme applications, rod bolts made of special ARP2000 material (rated at a 220,000 psi nominal tensile strength) are available, including those with the patented Wave-Loc design. Special high strength bolts also available for aftermarket connecting rods. Call for details.
ARP Head Stud Kit : 03 - 06 Mitsubishi Evolution EVO 8 & 9
Our Price: $95.00

It 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.

For openers, ARP® uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 190,000 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.

Following 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.

ARP 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.

Premium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import application. You 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.

ARP head stud kits are available with your choice of conventional hex nuts or compact 12-point nuts. Premium quality parallel ground washers are also included with each kit. Clearly, they are the best on the market today, and the favorite of leading professional engine builders in all forms of racing.
