ARP Main Stud Kits | Multiple Ford Fitments (255-5502)

The ARP Main Stud Kits are high-performance fasteners designed to secure engine main caps and prevent cap walk or fretting under demanding conditions. Constructed from 8740 chromoly steel and heat-treated in-house to achieve a tensile strength of 190,000 psi, these studs provide exceptional durability and strength. The precision J-form threads are rolled after heat treatment, resulting in significantly stronger threads compared to standard fasteners. The kits include hardened, parallel-ground washers and high-quality nuts, ensuring reliable clamping force and long-term performance. These main stud kits are engineered to enhance engine integrity, especially in high-stress applications, offering peace of mind during aggressive driving or racing.

Designed for multiple Ford fitments, including various engine configurations, the ARP main stud kits are suitable for engines requiring a robust and reliable fastening solution. They serve as direct replacements or upgrades for stock fasteners, ideal for performance builds, racing, or high-performance street applications. Installation involves replacing existing main cap bolts with these studs, providing a more secure and stable main cap connection. The kit includes all necessary components for a complete upgrade, ensuring compatibility with compatible Ford engines. These studs are perfect for enthusiasts seeking to improve engine reliability and longevity under extreme conditions.
