ARP - 234-5608 - 8740 Chrome Moly - Chevrolet - Automotive - Main Studs
ARP's Main Stud Kits are important for you to use if you want the best main stud kit. They help with the elimination of a main cap walk and fretting, as well as protecting the threads in your engine block. All ARP Main Stud kits come complete with hardened parallel-ground washers and high quality ARP nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely into place. The ARP Main Studs are manufactured from 8740 chrome moly steel, that is heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than any other.
