Upgrade your Chevy Duramax LB-7 or LLY 6.6L diesel engine with the Speedmaster PCE279.1035 Head Stud Kit. Manufactured from high-strength 8740 chromoly steel and featuring 12-point fastener heads, these head studs are engineered to provide superior clamping force and long-term reliability compared to stock head bolts — making them an ideal choice for performance builds, towing applications, and engines subjected to elevated cylinder pressures.
Designed specifically for Chevrolet and GMC trucks equipped with the Duramax LB-7 or LLY 6.6L diesel engine, this kit from Speedmaster offers a direct-fit solution to help maintain proper head gasket sealing integrity. The 12-point drive design allows for easier torquing in tight engine bay spaces, and the use of 8740 chromoly steel ensures excellent tensile strength and fatigue resistance for demanding diesel performance environments.
