ARP Main Stud Kits | Multiple Mopar Fitments (145-5602)

The ARP Main Stud Kit for multiple Mopar applications is a high-performance fastening 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 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 by maintaining proper cap alignment and reducing the risk of thread damage, making it suitable for high-performance and racing applications.

Designed for various Mopar engines, these main studs are compatible with a range of models and engine configurations. They serve as a direct replacement or upgrade for stock fasteners, offering increased clamping force and improved reliability under high-stress conditions. Ideal for street, track, or racing use, the kit simplifies installation with a bolt-on design that does not require additional modifications. The set provides all necessary components for a complete upgrade, ensuring a secure fitment and long-lasting performance in demanding engine builds.
