4BT FIRE RING GASKET KIT
At Industrial Injection, the PDM-4961 Fire Ring Cylinder Head Gasket Kit is built for modified Cummins 3.9L (4BT) diesel engines that demand improved combustion sealing. This kit includes precision fire rings designed for cylinder heads machined with a groove around each combustion chamber. When installed, the fire rings work with the head gasket to enhance sealing at the combustion chamber, helping maintain gasket integrity under increased cylinder pressure. Ideal for performance or high-load applications, this kit provides added durability where a standard gasket may fall short.
