Description

Part #: 402500-R

UMI Performance adjustable upper control arms are designed to optimize your vehicle's performance by allowing you to adjust the pinion angle. 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 strong 4140 chrome moly adjuster. One unique feature of UMI Performance's control arms is the on-car adjuster, which makes it easy to make adjustments without removing the control arm from the vehicle. Adjusting the pinion angle is crucial for reducing wheel hop, increasing traction, and improving 60-foot times on the track. Additionally, these control arms come with grease-able fluted polyurethane bushings, rear end housing bushings, and a durable powder coat finish. Overall, UMI Performance adjustable upper control arms are built with precision CNC machining, fully welded construction, and other premium features to enhance your vehicle's handling and performance.

UMI Performance adjustable upper control arms feature on-car adjustment, CNC machined 4140 chrome moly components, and polyurethane bushings. They reduce wheel hop, improve traction, and optimize pinion angle for better track performance.
