Ceramic Wheel Brearings: The ceramic balls in these hybrid bearings are over 60% lighter than their steel counterparts resulting in faster acceleration and reduced inertial loads.Low Friction-Less Vibration the coefficient of friction for the ceramic balls is an average of 3x's lower than steel. When you combine this with the high tolerances for roundness you get a bearing that dramatically lowers vibration levels and produces more horsepower. (set is front and rear rims) the kits can be purchased separately or as one complete kit
