ARP Main Stud Kits | Multiple Audi/Volkswagen Fitments (204-5408)

The ARP Main Stud Kit 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 significantly stronger threads compared to standard fasteners. The kit includes hardened, parallel-ground washers and high-quality nuts, ensuring a secure and reliable fit. This product enhances engine integrity by maintaining proper cap alignment and reducing the risk of thread damage, making it an ideal upgrade for high-performance or heavily modified engines.

Designed for multiple Audi and Volkswagen models, the ARP main stud kit fits various engine configurations requiring a robust main cap fastening solution. It is suitable for use in street, track, or racing applications where engine strength and reliability are critical. Installation involves replacing the stock main bolts with these high-strength studs, providing a direct bolt-on upgrade that improves engine stability under high stress. The kit includes all necessary components for a complete installation, ensuring a secure and long-lasting connection. Compatibility notes indicate suitability for engines that benefit from increased clamping force and thread integrity, making it an essential component for performance engine builds.
