UMI Performance's rear control arm kit for 1968–1972 GM A-body combines fully boxed lower arms with heavy-duty adjustable upper arms to reduce suspension deflection and wheel hop. Fully capped CNC radius ends and reinforced sway bar holes retain a factory appearance. On-car CrMo adjusters, Teflon-lined rod ends and greaseable polyurethane bushings provide precise adjustment; expect about a two-hour install and a durable powder-coat finish.
