UMI boxed lower control arms with Roto-Joints improve traction and handling.UMI's boxed lower control arms utilize Roto Joint technology for a bind free performance and comfortable ride quality. The control arms are fabricated from 0. 120 wall thickness rectangular tubing, with CNC machined bushing holders and MIG welded end caps for durability. The sway bar provisions are reinforced with a steel sleeve for added strength. The delrin lined Roto Joints eliminate flex and deflection for improved traction and reduced wheel hop.
