Industrial Injection 03-07 5.9L 24 Valve Fire Ring Gasket Kit Spec 4.550 (Our Spec For Our Heads)

This kit includes the fire ring gasket set specifically for 2003-2007 Dodge Ram 2500 and 3500 models with the 5.9L 24-valve Cummins engine. These gaskets are designed to work with Industrial Injection's own performance heads, featuring a 4.550-inch bore specification. The fire ring design creates a very strong seal between the cylinder head and the block, which is crucial for handling the increased cylinder pressures common in modified diesel engines.

Industrial Injection has put these gaskets together with durability in mind for demanding applications. The fire rings themselves are made from robust materials that help prevent blowouts and maintain compression even under significant boost. This kit is a well-built option if you're rebuilding the top end of your 5.9L Cummins and want a gasket that can handle more than stock power levels. Proper installation is key to ensuring these gaskets perform as intended, so be sure to follow the manufacturer's guidelines.
