Description

UMI Performance adjustable upper control arms are designed to optimize your vehicle's pinion angle for superior performance, precise handling, and increased traction. These control arms are made of high-quality materials, including CNC machined 0.250" steel mounting plates, 4140 chrome moly threaded tube adapters, and a 4140 chrome moly 1.000" solid adjuster. One unique feature of UMI Performance's adjustable upper control arms is the on-car adjuster, which allows for easy adjustments without the need to remove or unbolt the control arm from the vehicle. Adjusting your pinion angle is essential for improving your track times, enhancing traction, and minimizing wheel hop. These control arms also come with grease-able fluted polyurethane bushings, new rear end housing bushings, and a durable gloss powder coat finish for long-lasting performance and reliability. Upgrade your vehicle with UMI Performance adjustable upper control arms for optimal performance and improved handling.
