The pinion seal is critical for preventing differential fluid from leaking out of the housing where the pinion shaft enters. It also acts as a barrier to keep dirt and moisture from entering the differential.

What vehicles commonly use this pinion seal?

This seal is designed for 2014 and newer GM 9.5" and 9.76" 12-bolt rear differentials. This includes many models like the Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Chevrolet Tahoe.
