FAQ

Q: What is included in this “Top Gasket Kit”?
A: This kit typically includes the cylinder head gasket, valve cover gasket, intake and exhaust manifold gaskets, and other upper engine seals. It does not include lower engine gaskets (oil pan, front/rear main seals). Please verify your specific engine’s needs.

Q: Is this an OEM Cummins part or an aftermarket replacement?
