UMI’s Roto-Joint adjustable rear upper control arms are a valuable upgrade for any street or pro-touring car. They are designed for various driving conditions, whether on the street, strip, or carving corners. The premium spherical joint minimizes suspension deflection, ensuring precise handling, easy pinion angle adjustments, and reduced wheel hop. These adjustable upper control arms are simple to adjust while still attached to the car and are built to accommodate a wide range of applications.
The Roto-Joints, combined with UMI’s chromoly adjuster, deliver exceptional strength and performance. These heavy-duty arms feature CNC laser-cut mounting pads and a combination of TIG and MIG welding for enhanced durability. Installation is straightforward, taking only 1-2 hours with basic hand tools. They are compatible with all rear end housings, allowing for improved launching and cornering with UMI’s high-quality arms.
Made in the USA in Philipsburg, PA, these control arms offer on-car adjustment using UMI's chromoly adjuster, UMI-designed Roto-Joints, chromoly threaded adapters for added strength, CNC laser-cut ¼” upper mounting pads, and a durable powder coat finish. Upgrade your car with UMI’s top-notch control arms for better performance on the road or track.
