The UMI Performance 1968-1972 GM A-Body rear control arm kit pairs fully boxed lower arms from 3-inch x 1-1/2-inch rectangular tubing with adjustable upper arms that use CrMo adjusters.

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 fully boxed lower control arms are built from larger 3” x 1-1/2” rectangular tubing and feature CNC machined radius ends and reinforced sway bar holes. Boxed control arms include fully capped radius ends to prevent debris from entering to arm while offering the factory look to your classic. The heavy duty upper control arms feature on car adjustment using heavy duty CrMo adjusters and Telfon lined rod ends. Upper control arms feature heavy duty ¼” thick laser cut mounting pads 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.
