The Tommy Rail enhancement from ProMaxx Tool is an accessory to the Tommy Wheel Bearing Puller. It was engineered to handle greater power and the enhancement helps to reach its potential. The tool is made from solid, hard-coated aluminum. It attaches to the outside of the lower push flange creating a powerful structural link like an automotive four-bar linkage setup. Tommy can remove wheel bearing hubs without damage to the CV or knuckle and without the need for an expensive alignment.
