Mopar Main Stud Kit

The ARP Mopar Main Stud Kit (141-5401) is an essential upgrade for serious engine builders who demand reliability and performance. This kit is specifically designed for Mopar enthusiasts working on high-horsepower builds, including those utilizing forced induction or nitrous applications. By replacing factory bolts with high-quality chromoly studs, this kit ensures superior clamping force under extreme conditions.

Constructed from durable chromoly steel and featuring a shot-peened finish, the studs in this kit provide enhanced tensile strength compared to stock bolts. They are precision-engineered to maintain consistent preload across all main caps, preventing relaxation during thermal cycling and detonation events. This design helps protect against bearing failure and catastrophic engine damage, making it a critical component for performance builds.

Ideal for bracket racers, street strip warriors, and competitive builders, the ARP Mopar Main Stud Kit is compatible with Mopar's original block and cap geometry, eliminating the need for custom machine work. Each kit includes high-quality washers and is designed for straightforward installation using ARP's recommended torque specifications. This reliability ensures that your crankshaft remains securely in place, giving you peace of mind during high-performance applications.
