ARP (247-4202) Cummins Head Stud Kit 1998.5-2015 Cummins 5.9l/6.7l
To overcome head gasket failures that can occur in diesel
engines employed in truck and RV applications, industry leader ARP has
introduced extra heavy-duty head studs for the popular Ford, Dodge and GM
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
