ARP main stud kits help eliminate main cap walk/fretting and protect the threads in your engine block. They include studs made from 8740 chromoly steel and heat-treated in-house to 190,000 psi tensile-strength rating. 

The precision J-form threads are rolled after heat-treat for much stronger threads than the competition.

Kits come complete with hardened parallel-ground washers and high-quality nuts. Add confidence in the strength of your engine build with the ARP main stud kit designed for your application.
