First off, the pivot on a hanger is strictly meant for allowing the hanger to pivot on a single, stationary axis. Delrin is a very hard material, which will allow for the hanger to only rotate on that axis and not move from side to side. Many people have heard about urethane pivot cups. The softer urethane pivot cups allow for side to side movement when turning, leading to a sloppy truck. We believe that a precision made delrin pivot cup is ideal for use in a precision truck.
