ARP main bolts are built for the demands of professional engine builders and competition use. They’re forged from 8740 chrome moly steel and feature a reduced wrenching head, a large underhead radius, and rolled threads to support long-term reliability.
The threads are rolled after heat-treating, providing approximately 2000% better fatigue strength than main bolts threaded prior to heat-treating.
