Mopar Main Stud Kit - 5.9L Cummins 2-Bolt

The Mopar Main Stud Kit - 5.9L Cummins 2-Bolt by ARP is a crucial upgrade for serious Cummins diesel builders looking to enhance engine performance during high-output modifications. This kit is designed to replace factory main cap bolts, which are known weak points in stock 5.9L diesel engines, particularly under increased loads and boost conditions.

Constructed from premium Alloy steel and shot-peened for enhanced fatigue strength, these main studs provide the necessary clamping force and resistance to failure. The 2-bolt configuration is specifically designed for first-generation 5.9L Cummins platforms, ensuring a precise fit. ARP's pre-stretch technology and micro-polished finish further enhance the reliability and performance of these fasteners.

Ideal for applications involving aggressive tuning or heavy-duty use, this stud kit is particularly beneficial for dedicated pulling trucks or builds that frequently operate at high RPMs. Proper installation following ARP's torque specifications is essential for maximizing the performance and longevity of your engine.
