Increase rear suspension handling by replacing your weak factory stamped steel rear lower control arms and rubber bushings control arms with UMI's heavy duty tubular adjustable setup. These direct bolt-on replacements minimize wheel hop, improve corner handling while lowering ET's and help motorsports consistency. The spherical rod end allows for a “bind free” operation, making a great upgrade for both your track and auto cross driven car. The urethane bushings are designed to be bolted to the car chassis for a quiet comfortable operation. Control arms are constructed DOM mild steel tubing 1.500” OD x 0.120” wall, 4130 chrome-moly threaded tube adaptor, completely CNC machined and fully TIG welded for outstanding strength. Control arms feature high quality polyurethane bushings, zinc plated steel sleeves and “on-car” grease able zerk grease fittings.

Our lower control arms feature reinforced spring perches and heavy duty sway bar mounting points.
