Mopar Head Stud Kit - 5.9L 24V Cummins

The ARP Mopar Head Stud Kit for 5.9L 24V Cummins (part number 247-4204) is the premium fastening solution for diesel builders who demand reliability under extreme cylinder pressures. Designed specifically for the legendary Cummins turbodiesel platform, this head stud kit replaces factory bolts with superior ARP studs that provide consistent clamping force and dramatically improve head gasket longevity.

ARP head studs deliver higher tensile strength than OEM bolts, maintaining their preload through thermal cycling and the sustained heat cycles inherent to diesel operation. The 247-4204 kit features ARP's proprietary 8740 chromoly steel construction, precision-rolled threads, and a 180-degree arc under the head—all critical design factors that distribute load more evenly across the block deck surface.

Serious Cummins owners—from fleet operators running heavy towing loads to performance enthusiasts chasing reliable big-horsepower builds—recognize that investing in ARP head studs prevents catastrophic gasket failure, coolant intrusion, and the costly engine rebuilds that follow. Installation requires removing the cylinder head and using a torque-to-spec setting for optimal performance.
