Part Story

This cast 1350 pinion yoke fits the GM 10.5" differential with 2.20" seal ID. It takes the strap kit 3570-20. Seal 2286 will be needed if measured ID of seal is larger at 2.37"

In 2000 GM started using a synthetic oil which required a triple lip seal with a larger ground hub diameter.

This yoke will fit all 2000 an up trucks without changing the original seal.
