Buick 455 Main Bolt Kit

ARP 125-5201 High Performance Main Bolt Kit (2-bolt)
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 reliability. The threads are rolled after heat-treating which makes them about 1000% longer fatigue life than most main bolts which are threaded prior to heat-treating. The popular High Performance Series at a nominal rating of 180 000 psi are a premium
replacement for OEM fasteners. Parallel-ground hardened washers are included with each kit.
