Overview

Don’t let main cap walk sneak up and ruin your engine party. ARP Main Stud Kits lock things down with brute strength and engineered precision.

Each stud is crafted from 8740 chromoly steel and heat-treated to a beefy 190,000 psi tensile strength. Threads are J-form rolled after heat treatment for maximum fatigue resistance—stronger than your average fastener and probably stronger than your willpower on taco night.

The kit comes complete with high-quality hardened washers and premium nuts for a consistent, even clamp load. If you’re serious about building an engine that can take the heat (and the RPM), this is the stud kit to trust.
