Product Description
Build your own rebuild kit for the BW4406 / BW4407 transfer case. Case must have "44-06" cast in it (44-16 = BW4416, not this kit). Pick the overhaul kit that matches your case, then add only the parts you need.
Build your own BW4406 rebuild kit: choose the parts that match the transmission on your bench and leave out what you don't need. This builder has 7 option groups and 12 choices, all optional, so the kit holds only what you pick.
Brands offered in this kit include BorgWarner.
