ARP Main Stud Kits | Multiple Chevrolet Fitments (134-5502)

The ARP Main Stud Kit for multiple Chevrolet applications is a high-performance engine fastener solution designed to enhance engine durability and reliability. Crafted from 8740 chromoly steel and heat-treated to achieve a 190,000 psi tensile-strength rating, these studs provide superior strength compared to standard fasteners. The precision J-form threads are rolled after heat treatment, resulting in significantly stronger threads that resist stripping and fretting under high-stress conditions. The kit includes hardened, parallel-ground washers and high-quality nuts, ensuring a secure and stable main cap connection. This product is engineered to prevent main cap walk and thread damage, making it ideal for high-performance and racing engine builds.

Designed for a range of Chevrolet models, these main studs are suitable for engines requiring increased clamping force and stability. They are compatible with various engine configurations and serve as a direct replacement for stock fasteners, offering a reliable upgrade for street, track, or drag racing applications. Installation involves replacing the factory main bolts with these studs, providing a more consistent and secure main cap hold. The kit includes all necessary components for a complete upgrade, ensuring optimal engine integrity during demanding use cases.
