Ultra-thin EZ Sweep Castor Slip Plates allow you to drive your vehicle straight on, eliminating the need for any ramps or jacking your vehicle up. With 20 degrees of rotation, they are ideal for measuring castor, camber and kingpin inclination angles. This product has been engineered with a PTFE coated surface enabling it to slip, eliminating the necessity of grease and bearings. Robustly constructed with a stainless steel base, this allows for these turn plates to be placed on the floor or directly on top of scale pads. The EZ Sweep Castor Slip Plates are sold in pairs.
