An improved truck for use with a skateboard or roller skate. The truck has a truck hanger attached to a mounting bracket. The truck hanger has opposed axle elements for mounting a pair of opposed wheels. The truck hanger also has a hanger flange and a hanger pivot. The mounting bracket has a base plate, a pivot bore and a king pin. The truck hanger is affixed to the mounting bracket with the hanger pivot disposed within the pivot bore and with the hanger flange disposed over the king pin. A hanger flange is sandwiched between an inner cushion element and an outer cushion element. Both the inner cushion element and the outer cushion element have an elastomeric outer portion and a substantially rigid liner portion.
