The ARP main stud kit is engineered to eliminate main cap walk and fretting, while providing superior protection for the threads in your engine block. Each kit includes hardened parallel-ground washers and high-quality nuts. Select applications feature standoff studs and serrated lock nuts for secure windage tray mounting.

Manufactured from 8740 chrome moly steel and heat-treated in-house to a tensile strength of 190,000 psi, these studs feature precision J-form threads rolled after heat treatment, resulting in threads that are up to 2000% stronger than conventional alternatives.

ARP recommends main studs over bolts to achieve more accurate torque readings, as studs do not twist into the block and all clamping forces remain on a single axis. This reduces stress on block threads, which is especially important for aluminum blocks, and ensures easier assembly and consistent cap alignment.
