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 ARP 2000® 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.
