The Arp Diesel Head Studs Kit 230-4201 for your 2001-2016 GM Duramax. These head studs are a must have to overcome head gasket failure which can happen in high performance application. Rated at 220,000 psi tensile strength, they will provide great clamping force that's required to keep cylinder heads from lifting due to higher combustion pressure. They are compatible for GM Duramax Diesel trucks - LB7, LLY, LBZ, LMM, and LML.
The studs are manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. the ends of the studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Also included in each kit are heat-treat, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.
