Details

The Pro Body Tool is a precision CNC machined  sizing pin made from C.R. steel with zinc plating for corrosion  protection. Ensuring proper axle fit by reaming undersized wheel bores  (great for wheels that don't fit on the mandrel!). Ensures accurate  rotation by squaring the inner wheel hub to the wheel bore for proper  mounting on a Wheel Mandrel. Reduces the wheel hub to a car body braking  effect by accurately and easily coning the inside wheel hub.
