Kill Devil Diesel Fire Ring Head Gasket Kit 7.3 Powerstroke

This kit will eliminate head gasket problems at higher boost levels. Includes 8 solid steel fire rings, coolant support tubes, o-rings at coolant passages and detailed installation instructions. The 8 solid steel fire rings are to seal the combustion chamber and two gaskets that offer the same sealing characteristics (oil and water) as stock head gaskets. Accurate machining is extremely important and a hot re-torque is essential.
