ARP Main Stud Kits | Multiple Pontiac Fitments (193-5401)

The ARP Main Stud Kit for multiple Pontiac 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 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 threads that are significantly stronger than standard options. The kit includes hardened, parallel-ground washers and high-quality nuts, ensuring a reliable and secure fit. This product enhances engine integrity by providing consistent clamping force, reducing the risk of main cap movement under high-stress conditions, and supporting high-performance builds.

Designed for a range of Pontiac engines, these main studs are compatible with various models and years, offering a direct replacement for factory fasteners. They are ideal for street, strip, or race applications where engine strength and reliability are critical. Installation involves replacing the stock main bolts with these studs, providing a more secure and stable main cap connection. The kit includes all necessary components for a complete upgrade, ensuring proper fitment and performance. Suitable for engines requiring increased clamping force, these studs are an essential upgrade for high-horsepower or forced induction setups.
