CUMMINS GENUINE REAR MAIN SEAL WITH REPAIR SLEEVE 3926126 | 1989-2018 CUMMINS 5.9L/6.7L

Repair a leaking rear main seal on your Dodge Ram 5.9L or 6.7L Cummins with the Cummins 3926126 Genuine Rear Main Seal with Repair Sleeve. This genuine Cummins replacement kit is designed to restore proper sealing at the rear of the crankshaft and help prevent engine oil leaks.

The included repair sleeve makes this kit particularly useful for higher-mileage engines where the original crankshaft sealing surface has developed wear or grooves from prolonged contact with the rear main seal. The sleeve provides a renewed sealing surface for the new seal, helping achieve proper contact without requiring crankshaft replacement solely because of sealing-surface wear.
