ARP High Performance Series main bolts are rated at 180,000 psi and a popular premium replacement for OEM fasteners. Designed to meet the exacting standards and demands of professional engine builders, ARP bolts are forged from 8740 chromoly steel and 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 2,000 percent better fatigue strength than most main bolts that are threaded prior to heat-treating. Hardened parallel-ground washers are included with each kit.

Professional engine builders are familiar with camshaft walk. Excessive camshaft end play can produce erratic spark timing and the movement of the timing chain/gear can destroy the timing cover. Moroso has solved this problem with a wear resistant cam stop button that mounts in an aluminum holder, which bolts to the cam gear by way of a retaining plate. These button assemblies do not allow the cam to walk forward, stabilizing ignition timing and preventing costly engine damage.
