They utilize Currie Johnny Joints on both ends of each control arm which are free moving joints with ample misalignment and angle, rebuildable and greaseable and do not give the resisantance and misalignment wear charactoristics of all bonded rubber. They offer a isolated construction for decreased transmission of road vibrations without the wear or binding associated with bonded rubber joints.
