ARP Main Stud Kits
ARP main stud kits are designed to prevent main cap walk and fretting while protecting the threads in your engine block. These studs are made from 8740 chromoly steel and are heat-treated in-house to achieve a 190,000 psi tensile strength rating.
The precision J-form threads are rolled after heat treatment, providing superior thread strength compared to the competition. Each kit includes hardened parallel-ground washers and high-quality nuts for a secure, reliable installation.
Enhance the strength and durability of your engine build with the ARP main stud kit, specifically designed for your application.
