ARP main cap bolts feature a generous under head radius, rolled threads and a special heat-treating process that adds up to as much as 1000% longer fatigue life compared to most main cap bolts. They're forged from 8740 chromoly steel and each set of bolts comes with parallel ground, hardened steel washers for accurate torque readings.
