Far superior to any other main bolt kit offered for use in competition engines, ARP main bolts are designed to meet the exacting standards and demands of professional engine builders. Forged from 8740 Chrome-Moly , all bolts feature generous under-head radius and rolled threads for the utmost in reliability. The threads are rolled after heat treating, which gives them about 1000% longer fatigue life than most main bolts which were threaded prior to heat treating. Available in the popular high Performance series, which at a nominal rating of 180,000 psi is a premium replacement for OEM fasteners, or the 200,000 psi nominal rated pro series, application specific main bolts with reduced wrenching head are designed for use in custom applications. Parallel ground, hardened washers are included in each kit.
