UMI's tubular lower control arms are equipped with Roto-Joint technology for superior performance and a smooth ride. The Roto-Joint design allows for 28 degrees of unrestricted movement, reducing friction and improving handling over factory rubber and polyurethane bushings. This ensures a comfortable and quiet ride on both the street and the track.
The control arms are constructed from 1.500” x 0.120” DOM mild steel tubing and feature Roto-Joints on both sides. They come fully assembled and ready to install, using OEM hardware and a durable powder coat finish. The sway bar holes are reinforced with a steel sleeve for added strength.
UMI's Roto-Joint technology combines the benefits of a spherical rod end with the softer qualities of a bushing. The 4140 chrome moly spherical ball rotates in a delrin race, providing wear resistance and preventing suspension bind. The delrin material offers excellent wear resistance and tensile strength, ensuring long-lasting performance.
The Roto-Joint is adjustable and rebuildable, allowing for easy maintenance and extended durability. The optional spanner wrench can be used to adjust the tension on the delrin race and disassemble the Roto-Joint for cleaning and rebuilding.
Overall, UMI's tubular lower control arms with Roto-Joint technology offer improved performance, reduced wheel hop, and precise handling, making them ideal for both street and track applications.
