ARP Pro Series Main Bolt Kit Subaru WRX STI 02+

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 gives them about 1000% longer fatigue life than most main bolts, which are threaded prior to heattreating. Available in the popular 200,000 psi nominal rated Pro Series, application-specific main bolts with reduced wrenching head and are designed for use in competition applications. Parallel-ground, hardened washers are included with each kit.

Fits: 2.0L, 2.2L & 2.5L SOHC/DOHC EJ Series Crankcase thru bolt kit
