Product Description
Build your own rebuild kit for the ZF S6-650 / S6-750 manual transmission. ONE Ford builder covers S6-650 and S6-750 because bearings, seals, synchros, 5th parts and fork are shared (BK486WS is sold for both). Pick the overhaul kit that matches your case, then add only the parts you need.
Build your own ZF6 rebuild kit: choose the parts that match the transmission on your bench and leave out what you don't need. This builder has 8 option groups and 28 choices, all optional, so the kit holds only what you pick.
