Fire Ring Engine Gasket for 24V Cummins

If you’re building a high-performance 5.9L 24V Cummins and pushing boost beyond what the factory head gasket was ever meant to handle, the Industrial Fire Ring Gasket is exactly what you need to hold it all together. Designed for the 1998.5–2002 Dodge Ram 2500 and 3500, this gasket kit is a go-to upgrade when reliability under extreme cylinder pressures is a top priority. Whether you're prepping for track passes, sled pulls, or just want peace of mind on a hard-working street build, this setup is built to keep the seal tight when it matters most.

Designed for a Precise Fit

The gasket comes paired with precision-cut fire rings that measure 4.550 inches in diameter, with a .105" thickness and a groove spec of .034"–.036". It’s ideal for applications where a machine shop is cutting the grooves into the cylinder head, or you can order one of Industrial’s pre-machined heads and be ready to go out of the box. Just keep in mind—this setup isn’t compatible with factory head bolts. You’ll want to use a set of quality head studs to get the full clamping force and security that a fire ring setup demands. With the right prep and installation, this gasket helps eliminate the common failure point between the block and head when running high boost or extreme cylinder pressure. If you’re serious about performance and aren’t interested in making compromises, this is the kind of part that keeps you on the throttle instead of tearing things down again.

Fits: 1998.5, 1999, 2000, 2001, 2002 Dodge 2500/3500 5.9L Cummins 24V
