1968-1972 GM A-Body Tubular Upper Control Arms Black

UMI Performance adjustable upper control arms feature CNC-machined 0.250 in. mild steel, 4140 chromoly threaded tube adapters, and a high-strength, 4140 chromoly, heat-treated, 1.000 in. solid adjuster. With UMI Performance adjustable upper control arms, you can easily make pinion angle adjustments in the garage or at the track--it's as simple as loosening two nuts! Simply turn UMI's unique chromoly on-car adjuster with the control arms on the car to quickly lengthen or shorten the control arms. Pinion angle adjustments are a must when wanting to lower your track 60 ft. times, increase traction, and reduce unwanted wheel hop. Their PTFE-lined spherical rod end design allows for "bind-free" operation, making them great upgrades for both your track and autocross-driven vehicle.
