ARP Main Stud Kits | Multiple Ford Fitments (150-5802)

The ARP Main Stud Kit for multiple Ford fitments 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 190,000 psi tensile-strength rating, 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 reliable clamping force and long-term performance. This product enhances engine integrity by maintaining proper main cap alignment and reducing the risk of thread damage, making it ideal for high-performance and racing applications.

Designed for a variety of Ford engines, these main stud kits are suitable for models requiring a robust fastening solution. They are compatible with engines that demand increased clamping force and improved reliability, especially in high-stress environments such as racing or forced induction setups. The installation involves replacing the stock main bolts with these bolt-on studs, providing a secure and stable main cap connection. The kit is a direct replacement for OEM fasteners, offering a straightforward upgrade for engine builders seeking increased strength and peace of mind. Suitable for street, track, or off-road use, these studs are essential for maintaining engine integrity under extreme conditions.
