The ARP 625+ head studs of your Dodge Cummins 5.9L 12V for 1989-1998 have a tensile strength of 260,000 psi and provide the clamping force needed to prevent cylinders from lifting because of higher combustion pressure. A must if you replace head gaskets.
  • 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 power plants. These ARP 625+ studs are rated at 260,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.

    The studs are produced from the proprietary ARP Custom Aged 625+ material in ARP's Santa Paula, CA plant. Threads roll after heat treatment to ensure optimal strength of fatigue. They are centerless ground for perfect concentration. To facilitate easy installation, the ends of the studs are broached. This feature also allows for the removal of the cylinder head in tight quarters. Heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers are also included in each kit.

    All ARP 625+studs are centerless ground, heat treated prior to thread rolling and machining, nominally rated at 260,000psi tensile strength and are reusable as compared to the OEM Torque-To-Yield (TTY) head bolts. Optimum design, enhanced reliability and increased strength are the main attributes of ARP's Pro Series stud kits.
