Maintains Crankshaft Alignment & Proper Seals

Ensure your engine's durability and performance with the PPE Main Stud Kit. Designed to address the common failure point of stock main cap bolts, this kit is essential for maintaining crankshaft alignment and proper seals at the main bearing caps. Stock bolts can yield under performance applications or even under normal conditions as stress cycles accumulate, potentially leading to catastrophic engine failure.

Reduced Stress Concentration & Higher Fatigue Resistance

Constructed from premium chrome-moly alloy, PPE Main Studs boast over 215,000 psi yield strength and over 230,000 psi tensile strength. Each stud is heat-treated, centerless ground, and thread rolled for reduced stress concentration and higher fatigue resistance. Precision broaching via EDM and a black oxide finish ensure top-level performance and durability. The kit includes an assembly lubricant packet for uniform load distribution and accurate torque readings, making it a comprehensive solution for your engine's needs.

Fits: 2001-2005 GM 6.6L Duramax
