FAQ

Q1: Is this kit a direct replacement for the original Cummins parts?
Yes, this is a direct OEM replacement. The part numbers 4955356 and 4955357 are the official Cummins references for the upper and lower gasket sets. This kit is manufactured to meet or exceed the original equipment specifications for a perfect, leak-free seal.

Q2: What is included in the “Upper” vs. “Lower” gasket set?
The Upper Set (4955356) typically includes gaskets for the cylinder head, valve cover, intake/exhaust manifolds, and fuel system. The Lower Set (4955357) includes gaskets for the oil pan, front and rear crankshaft seals, timing cover, and other lower block components. This combined kit provides everything needed for a full engine rebuild.

Q3: What is the recommended installation procedure?
For optimal results, the engine block and cylinder head surfaces must be clean and free of old gasket material. Ensure you follow the manufacturer’s torque specifications and tightening sequence for the cylinder head bolts. We recommend using a high-quality thread locker and sealant on specified bolts and components as detailed in the Cummins service manual for the QSB4.5 engine.
