Description
Part #: 3656-B
Rear control arms are one of the most important suspension modifications that can be done to your GM vehicle. Stock control arms are on the borderline of "junk", bushing deflection and rusting weak stamped material add for traction loss and poor handling ability. The included Energy Suspension polyurethane bushings are an excellent improvement over the OEM rubber bushings, while adding ride improvements they also work excellent to reduce traction loss. These control arms are a direct bolt-on replacement designed to minimize wheel hop, improve cornering and help track consistency. Whether your vehicle is a street car, drag racer or a restoration project these arms are perfect for any set-up.
UMI rear control arms upgrade weak GM factory arms with DOM steel, TIG welds, and greaseable poly bushings. Improve traction, reduce wheel hop, and sharpen handling. Fits 3-link or 4-link setupscheck if your vehicle needs one or two uppers
