ARP Main Stud Kits
ARP main stud kits are designed to eliminate main cap walk and fretting while protecting the threads in your engine block. Each kit includes studs manufactured from 8740 chromoly steel, heat-treated in-house to an impressive 190,000 psi tensile strength rating.
The precision J-form threads are rolled after heat treatment, providing threads that are significantly stronger than those of the competition. Kits come complete with hardened parallel-ground washers and high-quality nuts to ensure reliable performance.
