ARP Main Stud Kits | Multiple Ford Fitments (151-5402)

The ARP Main Stud Kit for multiple Ford applications is a high-performance fastener solution designed to secure engine main caps and prevent cap walk or fretting under demanding conditions. Crafted 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 kit includes hardened, parallel-ground washers and high-quality nuts, ensuring reliable clamping force and long-lasting performance. This product enhances engine integrity by maintaining proper main cap alignment and reducing the risk of thread damage during high-stress operation.

Designed for a variety of Ford engines, these main studs are suitable for applications requiring increased clamping force and reliability. They are compatible with specific Ford models and engine configurations, serving as a direct replacement or upgrade for stock fasteners. Ideal for high-performance street, track, or racing builds, these studs are engineered to withstand extreme conditions and maintain engine stability. Installation involves replacing existing main cap bolts with these studs, providing a secure and consistent hold. The kit offers a comprehensive solution for builders seeking to improve engine durability and performance in demanding environments.
