The ARP Main Stud Kit for multiple Mopar applications is a high-performance engine fastener solution designed to secure the 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 by providing superior clamping force and reducing the risk of thread damage under high-stress conditions, making it ideal for performance builds and demanding applications.

Designed for a variety of Mopar engines, these main studs are compatible with specific vehicle models and engine configurations. They serve as a direct replacement or upgrade for stock fasteners, offering increased strength and reliability for street, strip, or racing use. Installation involves replacing the original main cap bolts with these studs, which are engineered for precision fitment and long-lasting performance. The kit provides all necessary components for a complete upgrade, ensuring optimal engine stability and performance under high horsepower and torque conditions. Suitable for use in performance and racing environments, these studs help maintain engine integrity during extreme operation.
