Give the pinion bearing a fresh running surface with the Schaeffler Differential Pinion Race NP912904. This Schaeffler cup is cataloged for the rear inner position. It is a direct-fit replacement for many vehicles, among them the 1997-2008 Ram 1500, 1997-2008 Dodge Ram 1500 and 2000-2010 Dodge Dakota. See the Buyer's Guide tab for the full list and engine-specific fitment.
The race is the outer ring of a tapered roller bearing. The bearing's rollers ride against it as the pinion turns. This listing is the cup (race). Schaeffler uses tapered roller bearings in wheel bearings, transmissions, differentials, transfer cases and other applications, and makes more than 100 million of them each year.
