UMI's boxed lower control arms utilize our Roto-Joint technology for a bind free performance and quiet comfortable ride quality. The boxed control arms are fabricated from 0.120" wall thickness rectangular tubing, CNC machined drawn over mandrel bushing holders and MIG welded end caps to keep out unwanted road debris. Each control arm features the correct provisions for adding a stock or aftermarket rear sway bar, sway bar holes are reinforced with a 0.120" wall thickness steel sleeve that is TIG welded and sanded into place. The solid construction combined with the delrin lined Roto-Joints eliminate control arm flex and bushing deflection for improved traction and reduced wheel hop. The installed Roto-Joint 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 polyurethane bushings on one end and UMI's swivel Roto-Joint on the other end. This set-up is designed for street performance and street enthusiast. The polyurethane bushing end is designed to be bolted to the vehicle chassis side while the Roto-Joint attaches to the rear end side. Since the polyurethane bushings are softer they are designed to absorb more road noise and shock before it enters the passenger compartment of the vehicle.
