Cylinder Head Stud Kit – 2001-2016 DK-GM6.6-STUD

Description

GM Duramax 6.6L LB7/LLY/LBZ/LMM/LML – 2001-2016 – DK Head Stud Kit

These studs ensure proper sealant between the cylinder head, head gasket, and cylinder block.  The stock design used bolts that would eventually lead to blown head gaskets and other issues due to the fact that the bolts would be pushed beyond their limitations.  Studs are used to tighten the seal and also restrict the amount of stretching and twisting of the studs by acting as a clamp instead of a bolt.

Our 6.6L studs have an ultimate tensile strength of more than 225,000 psi compared to leading brands rated at 220,000.
