Product Description
CUMMINS 3283333 OEM CYLINDER HEAD GASKET – 3.9L 4BT (STANDARD THICKNESS)
The genuine CUMMINS 3283333 OEM cylinder head gasket is the factory-standard sealing component for the legendary 3.9L 4BT engine. Engineered by Cummins with the correct multi-layer construction and crush thickness, this gasket provides proper combustion sealing, coolant containment, and long-term durability in both stock and industrial-duty applications. Whether you’re refreshing a high-hour 4BT, rebuilding a swapped engine, or preventing a future head gasket failure, this OEM-standard-thickness gasket delivers the reliability your engine deserves.
