Product Description
CUMMINS 3802820 OEM FRONT CRANKSHAFT SEAL WITH WEAR SLEEVE – RAM 5.9L/6.7L (1989–2018)
The CUMMINS 3802820 Front Crankshaft Seal with Wear Sleeve is the OE-spec solution for repairing front main seal leaks on 1989–2018 Dodge/Ram 5.9L and 6.7L Cummins engines. This kit includes both the front main oil seal and a precision wear sleeve — ideal for high-mileage engines with a worn or grooved crankshaft snout. Installing the wear sleeve restores a proper sealing surface so the new seal can seat correctly, eliminating oil leaks caused by crankshaft wear. Using a genuine Cummins kit ensures factory-fitment, correct elastomer material, and proper lip geometry for long-lasting service.
