Billet offset upper control arm shafts are available that fit stock upper control arms and most tubular upper arms. The offset shaft is used to gain more latitude for the alignment. It is generally used for racing applications or if a more aggressive alignment is desired. The offset shaft can also be used if alignment can not be achieved do to frame issues. The shafts are extended to accommodate different types of bushings including Del-a-lums. The shaft kit is sold individual so two kits will be required if you are changing both sides. The kit comes with washers and nuts for the bushings and is gold zinc plated.
