The ARP Main Stud Kits are high-performance fasteners designed to secure engine main caps and prevent cap walk or fretting during operation. Crafted from 8740 chromoly steel and heat-treated in-house to achieve a 190,000 psi tensile-strength rating, these studs provide exceptional strength and durability. The precision J-form threads are rolled after heat treatment, resulting in stronger, more reliable threads compared to standard fasteners. The kits include hardened, parallel-ground washers and high-quality nuts, ensuring a secure and consistent fit. These main stud kits are engineered to enhance engine integrity, especially under high-stress conditions, making them ideal for performance builds and demanding applications.

Designed for multiple Ford applications, these ARP main stud kits are suitable for a range of engine configurations. They serve as a direct replacement for stock fasteners, offering increased clamping force and improved reliability. The kits are suitable for street, track, or racing environments where engine stability is critical. Installation involves replacing the stock main cap bolts with these high-strength studs, washers, and nuts, ensuring a secure fit. Compatibility notes indicate they are intended for specific Ford models, and proper torque specifications should be followed for optimal performance. These studs are an essential upgrade for maintaining engine integrity during high-performance or heavy-duty use.
