ARP Main Stud Kits | Multiple Ford Fitments (151-5406)

The ARP Main Stud Kit for multiple Ford applications is a high-performance engine fastener solution 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 provide exceptional durability and strength under demanding conditions. 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 in high-performance or modified engines, by maintaining proper main cap alignment and reducing the risk of thread failure.

Designed for a range of Ford engines, these main studs are suitable for various models requiring a robust fastening solution. They serve as a direct replacement or upgrade for stock fasteners, ideal for street, track, or racing applications where engine strength and reliability are critical. Installation involves replacing existing main cap bolts with these studs, providing a bolt-on upgrade that improves clamping force and overall engine stability. The kit typically includes all necessary components for installation, making it a comprehensive solution for engine builders seeking to enhance durability and performance in Ford-based engines.
