Genuine Cummins 3802376 Lower Engine Gasket Kit | 5.9L 6BT 12V

The Genuine Cummins 3802376 Lower Engine Gasket Kit (frequently referred to as a bottom-end conversion gasket set) is a comprehensive OEM collection of high-durability seals engineered to completely refresh the crankcase and lower-block architecture. Specially compiled to streamline bottom-end overhauls or extensive oil-leak repairs, this full-coverage kit provides every critical boundary seal needed where the engine block interfaces with auxiliary housings and oil pathways. Relying on cheap, unbranded aftermarket sets risks catastrophic oil pressure drops or immediate weeping around the main seals; upgrading to a factory-certified Cummins kit ensures absolute dimensional accuracy and material integrity under extreme internal oil temperatures. This multi-piece kit restores original factory tolerances to eliminate unmanaged oil loss and protect the vehicle from premature wear. Complete Crankcase Sealing: Features a complete assortment of lower-engine sealing components, including the primary oil pan gasket, timing gear housing cover gasket, water pump seals, and oil cooler core gaskets. Premium Crankshaft Seals: Includes high-integrity front and rear crankshaft main seal kits built to withstand continuous rotational friction and prevent rear block oil weeping. Legendary 5.9L Compatibility: Precision-matched for an exact fit on Cummins 6B, 6BT, and 6BTA 5.9-liter mechanical 12-valve engines (covering models with VE or P7100 mechanical injection pumps). Multi-Sector Application: Universally certified for heavy-duty performance across Regular Pickup Trucks (1989–1998 Dodge Ram 2500/3500), industrial construction equipment, agricultural tractors, and marine power units.
