Product Description
Build your own rebuild kit for the NP261 / NP263 (HD / XHD) transfer case. Separate builder because bearing kit, gasket kit, chain, sprockets, mainshaft, input shaft and rear case all differ from the HD. Pick the overhaul kit that matches your case, then add only the parts you need.
Build your own NP263 rebuild kit: choose the parts that match the transmission on your bench and leave out what you don't need. This builder has 9 option groups and 18 choices, all optional, so the kit holds only what you pick.
Brands offered in this kit include BorgWarner, Sonnax.
