ARP Main Stud Kits | Multiple Dodge Fitments (247-5401)

The ARP Main Stud Kit is a high-performance fastener 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 190,000 psi tensile-strength rating, these studs provide exceptional strength and durability. 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 under high-stress conditions, making it ideal for performance builds and demanding applications.

Designed for multiple Dodge models, the ARP main stud kit fits a variety of engine configurations requiring main cap reinforcement. It is suitable for use in street, strip, or race engines where maintaining proper main cap alignment is critical. The installation involves replacing stock fasteners with these bolt-in studs, providing a direct upgrade for increased strength and reliability. The kit is comprehensive, including all necessary components for a complete installation. Compatible with engines that require main cap studs, it offers a robust solution for high-performance and heavy-duty applications.
