Part Story

Speedy sleeve can be removed and will expose a machine surface dimension of 1.940". This is a machined surface """not a ground hub""". See 3504-85 if 1.940" seal hub is needed.

This 1350 pinion yoke fits the GM 9.5" differential. It takes the strap kit 3570-20 and includes a new pinion seal.

This pinion seal will be necessary on all applications before 2000. 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 and up trucks without changing the original seal.
