The KAD pinion bearing support housing reinforces the free end of the main-shaft, this gives better pinion gear life as it prevents the pinion gear from trying to climb the crown wheel under hard acceleration. This support bearing housing can be used on other 4-speed gear kits if the speedo drive end is ground to 17mm which is the inner bearing race internal diameter. Mainshafts are under 17mm diameter would need sleeving up to 17mm diameter.
Our KAD Pinion Support Housing is unlike any other Pinion Support Housing on the market. Our 1 piece cast housing with integral ribbed support offers the ultimate in rigidity. Our pinion support bearing housing will allow the speedo drive to be used if required
