UMI's tubular lower control arms utilize our Roto-Joint technology for a bind free performance and quiet comfortable ride quality. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The installed UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation on any street or track driven vehicle. This control arm set features Roto-Joints on both sides of the control arms. This is designed for maximum performance and suspension travel. Both control arms feature the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are reinforced with a 0.120" wall thickness steel sleeve that TIG welded and sanded into place. All Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser or race car!
