Please Note: According to Cummins Technical Service Bulletin TSB100455, "The new-style cylinder head gasket, Part Number  3977063 , replaces cylinder head gaskets 3945803 and 3957650. The new design provides for improved sealing and clamp load retention over the previous designs. The new-style cylinder head gasket, Part Number  3977063 , can be identified by the addition of a third metal compression limiter on the exhaust side of the gasket. The old-style gaskets 3945803 and 3957650, have been obsoleted and are superseded by the new-style gasket."

Our complete line of seals and gaskets are produced from Interface materials. These materials are environmentally friendly, free of solvents and asbestos. Our seals and gaskets are made with high technology tools to guarantee an exact dimension and a proper fit, reducing the risk of leakage and increasing operational life.
