MAIN BEARING CAP STUD KIT 289/302 W/2-BOLT MAIN
ARP High Performance Main Bearing Cap Stud Kit for 2-bolt main 289/302.
Studs are generally better than bolts in that they eliminate main cap "walk" and fretting, as well as protect the threads in your block from being stripped or cross-threaded. ARP stud kits feature 6-point aircraft grade nuts with parallel-ground, hardened washers. Made from 8740 chrome moly steel, all stud sets are heat treated to 190,000 PSI and exceed aircraft quality standards. The threads are rolled after heat treating, which gives them about 1000% longer fatigue life than most main studs, which are threaded prior to heat-treating.
