Description

The ARP Diesel Head Stud Kit 230-4201 is a must have in any high performance 2001-2016 GM 6.6L Duramax. To overcome head gasket failures that can occur in diesel engines in these high performance applications, industry leader ARP has introduced extra heavy-duty head studs for the popular GM LB7, LLY, LBZ, LMM, LML Duramax powerplants. These ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.

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-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.

Features:
  • ARP 2000 Material
  • 220,000 PSI Tensile Strength
  • Chrome-moly Steel, 12-Point Nuts
  • Parallel-Ground Washers
