1998.5-2002 Cummins Fire Ring Gasket Kit (PDM-54174)

Industrial Injection fire ring head gasket kit for 1998.5-2002 Dodge Ram 2500/3500 5.9L 24V Cummins. The right head gasket setup for trucks pushing high boost levels where the OE composite head gasket lifts and fails — the fire ring locks the combustion chamber to the head and dramatically increases gasket pressure capacity.

This is the standalone fire ring kit — the head must be machined with the correct groove dimensions for the rings to seat properly. Comes with installation instructions for your machine shop. Industrial Injection's Performance Head (PDM-24VSTH) comes pre-grooved if you want a turnkey solution.
