UMI Performance lists the 1968-1972 GM A-Body rear control arm kit, which has boxed lower arms from 1/8-inch wall mild steel tubing and fixed-length upper arms with ¼-inch thick mounting pads.

UMI’s rear control arm kit is a bulletproof addition to your car. Suitable for street, strip or corner carving, this kit minimizes suspension deflection for a crisp handling setup and less wheel hop. The boxed lower control arms feature reinforced sway bar mounting holes to allow factory style sway bar mounting, including UMI’s popular 1” version. The upper fixed length control arms feature a heavy duty ¼” thick laser cut mounting pad designed to work on all rear end housings. UMI’s control arms are CNC machined for accuracy and assembled with high quality greaseable polyurethane bushings.
