Seal your 2007.5-2018 Dodge / Ram 6.7L Cummins with the Hamilton Cams Fire Ring Head Gasket, designed for ultimate reliability and sealing under high performance conditions. This gasket ensures a superior seal for engines pushing the limits, choose between stock thickness for standard builds or a +0.20" thicker option for enhanced clamping force and durability in high-horsepower setups.

NOTE: Installation of a fire ring gasket requires high yield head studs to ensure proper seat of the head to the cylinder block.

INSTALL TIPS:

For optimal performance, machine the head and block to flatness prior to installation. For engines under 800hp, cutting grooves in either the head or block suffices, but for power levels beyond 800hp, grooves in both are highly recommended. The radiused grooves should measure .013” deep in both block and head or .025”-.026” deep if only one groove is cut. Using a .105” wire with a 4.560” diameter, this gasket ensures a perfect seal. Proper torque procedure is essential, and head studs are highly recommended for achieving consistent clamp load. Use ample lubrication on nuts, washers, and threads to ensure even torque distribution, preventing potential gasket failure. Torque studs to 130 ft-lbs. for initial startup, re-torque after reaching operating temperature, and check valve lash after each sequence to maintain precision. Recheck at least once more before pushing your engine to full load or RPM.
