ARP Main Stud Kits | Multiple Ford Fitments (154-5604)

The ARP Main Stud Kit for multiple Ford applications is a high-performance hardware solution designed to secure engine main caps and prevent cap walk or fretting during operation. 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 under demanding conditions. 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 a reliable and secure fit. This product enhances engine integrity by maintaining proper cap alignment and reducing the risk of thread damage, making it ideal for high-performance or heavily modified engines.

Designed for a range of Ford models, these main stud kits are suitable for engines requiring a robust fastening solution. They are intended for use in performance builds, racing, or high-stress applications where maintaining proper main cap torque is critical. The installation involves replacing stock main bolts with these bolt-in studs, providing a direct upgrade that improves engine reliability. Compatibility covers various Ford engines, and the kit typically includes all necessary components for installation. These studs are suitable for street, track, or off-road use, offering increased strength and peace of mind during demanding driving conditions.
