ARP Main Stud Kits | Multiple Chevrolet Fitments (235-5606)

The ARP Main Stud Kits are high-performance fasteners designed to secure engine 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 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 kits include hardened, parallel-ground washers and high-quality nuts, ensuring a secure and stable engine assembly. These main stud kits are engineered to enhance engine integrity, especially in high-performance or forced induction applications, by maintaining proper cap alignment and reducing the risk of thread damage.

Designed for a variety of Chevrolet models, these ARP main stud kits are suitable for engines requiring a robust fastening solution. They are compatible with multiple Chevrolet applications, offering a direct replacement for stock fasteners. Ideal for street, strip, or track use, these studs help improve engine reliability during high-stress conditions. Installation involves replacing the stock main cap bolts with these high-strength studs, washers, and nuts, providing a bolt-on upgrade that enhances overall engine stability. The kit ensures a secure fitment and is suitable for use in performance builds requiring increased clamping force and thread integrity.
