ARP 207-4203 12-Point Head Stud Kit For 94-99 Mitsubishi 4G63 UP M11

To overcome head gasket failures that can occur in diesel engines, industry leader ARP has introduced extra heavy-duty head studs for them. These ARP studs are rated at 200,000 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 8740 chrome moly, 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:

• Cylinder Head Studs
• 200,000 PSI Tensile Strength
• Chrome-moly Steel, 12-Point Nuts
• Parallel-Ground Washers

Note:

• Fits Mitsubishi 4G63 engines
