UMI's rear trailing arms for the fifth generation Camaro 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 trailing arm set is designed to minimize wheel hop, maximize caster settings and increase rear end stability. UMI’s trailing arms are fabricated from 1” x 2” rectangular tubing and feature ¼” thick CNC machined mounting plates and are supplied fully assembled with Roto-Joints. Trailing arms are a direct bolt in and installation time is less than an hour using basic hand tools.
