UMIs 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. Kit includes UMIs premium fully boxed lower control arms designed to offer a factory look while still providing enhanced performance to the vehicle. 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 Chromoly adjusters and Telfon lined rod ends. The premium rod ends work as a solid bushing control arm with suspension articulation, designed for harder launches and less friction. Upper control arms feature heavy duty ¼ thick laser cut mounting pads designed to work on all rear end housings. UMIs control arms are CNC machined for accuracy and assembled with high quality greaseable polyurethane bushings.
