UMI's tubular upper 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. These control arms are a direct bolt on replacement designed to minimize wheel hop, improve cornering and help track consistency. Constructed of 1.500” x 0.120” DOM tubing and feature .250” thick CNC machined mounting plates these control arms are some of the beefiest on the market. Control arms are supplied with Roto-Joints fully assembled and are ready to be installed. Roto-Joints are greaseable and low maintenance making an excellent street setup for your cruiser!
