PRODUCT DESCRIPTION

Eliminate wheel hop, increase traction, and enhance handling performance with UMI Performance’s adjustable upper control arms. Featuring on-car adjustability and spherical Roto-Joints, these control arms provide 28 degrees of unrestricted movement for bind-free, low-friction operation. The Roto-Joint design outperforms factory rubber and aftermarket polyurethane bushings, ensuring correct suspension articulation and precise handling. The delrin race lining the spherical ball absorbs shock and road noise, delivering a smooth and quiet ride for both street and track-driven vehicles.

With on-car adjustability, UMI’s upper control arms allow for easy pinion angle adjustments, which are vital for lowering track 60-foot times, increasing traction, and reducing wheel hop. Using a chrome moly heat-treated adjuster, you can quickly make pinion angle changes by turning the adjuster while keeping the control arms attached to the vehicle. The mounting plate is CNC machined from 0.250” thick mild steel, and the control arms come fully assembled and ready to install with OEM hardware. They also feature a durable powder coat finish for long-lasting performance.

UMI's Roto-Joint technology allows for 28 degrees of total rotation and unrestricted movement throughout the suspension, merging the benefits of a spherical rod end with the comfort of a softer bushing. The Roto-Joint consists of a 4140 chrome moly spherical ball rotating in a delrin race for superior wear resistance and durability. Moreover, the Roto-Joint is adjustable and 100% rebuildable, with a spanner wrench available for adjustments and disassembly as needed. Enhance your vehicle's handling and performance with UMI Performance's adjustable upper control arms featuring Roto-Joint technology.
