The UMI rear control arm kit for 1964–1967 GM A-body replaces stock arms with fully boxed lower arms and adjustable heavy-duty uppers to reduce suspension deflection and wheel hop. Fully boxed lowers use 3" x 1-1/2" rectangular tubing with CNC-machined radius ends and capped ends. Uppers offer on-car CrMo adjusters and Teflon-lined rod ends, greaseable polyurethane bushings, powder-coat finish and an estimated two-hour install.
