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.

Additional features include:

* On-car adjustability
* 3/4 in. hard chrome plated PTFE/KEVLAR® self-lubricating race rod ends
* Precision CNC-machined and fully welded
* CNC-machined 6061 aluminum step bushings
* Durable powdercoated finish
