* Kits made up of multiple items may not show an inventory in-stock status but are almost always in stock!

tech note

If you are leaking transmission fluid into the transfer case, chances are your old input seal is worn out or the lips have hardened with age.

tech note

Remember to order the matching gaskets! You will definitely need the adapter to transfer case gasket when changing this seal.

tech note

Seal lips are factory pre-greased for initial lubrication.
