ARP Main Stud Kits | Multiple Ford Fitments (155-5401)

The ARP Main Stud Kit for multiple Ford fitments is a high-performance engine fastener set designed to secure main caps and prevent cap walk or fretting during operation. Crafted from 8740 chromoly steel and heat-treated in-house to achieve a tensile strength of 190,000 psi, these studs offer exceptional durability and strength. The precision J-form threads are rolled after heat treatment, resulting in stronger, more reliable threads compared to standard fasteners. The kit includes hardened, parallel-ground washers and high-quality nuts, ensuring a secure and consistent fit. This product enhances engine integrity, especially under high-stress conditions, making it ideal for performance builds and racing applications.

Designed for a range of Ford engines, this main stud kit is compatible with various models requiring main cap reinforcement. It is suitable for engines subjected to increased power and stress, providing a reliable solution for street, track, or drag racing setups. Installation involves replacing the stock main bolts with these high-strength studs, offering a bolt-on upgrade that improves engine stability and longevity. The kit includes all necessary components for a straightforward installation, ensuring proper clamping force and minimizing the risk of main cap movement during demanding driving conditions.
