UMI Performance adjustable upper control arms are designed to optimize your vehicle's performance by allowing you to adjust the pinion angle for improved handling and traction. These control arms are made with high-quality materials, including CNC machined 0.250" steel mounting plates, 4140 chrome moly threaded tube adapters, and a 4140 chrome moly solid adjuster. One of the key features of these control arms is the on-car adjuster, which makes it easy to make adjustments without removing the control arm from the vehicle. By adjusting the pinion angle, you can lower your track times, increase traction, and reduce wheel hop. Additionally, these control arms come with grease-able fluted polyurethane bushings and a durable gloss powder coat finish. Overall, UMI Performance adjustable upper control arms are built for precision and durability, making them an essential upgrade for any performance enthusiast.
