Forged from 8740 chrome moly steel, all ARP main bolts feature a reduced wrenching head, large underhead radius and rolled threads for the utmost in reliability. The threads are rolled after heat-treating which gives them about 2000% better fatigue strength than most main bolts that are threaded prior to heat-treating. The popular High Performance Series is rated at 180,000 psi, and is a premium replacement for OEM fasteners. Pro Series main bolts are application-specific, rated at 200,000 psi, and designed for use in competition engines. Hardened parallel-ground washers are included with each kit.
