STANDARDUMI'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.
Spanner Wrench- This spanner wrench is used for adjusting and disassembling of Roto-
Joints used in all UMI Performance products. Over time if the delrin race inside the Roto-
Joint would wear the spanner wrench is used to tighten the adjusting ring applying more
pressure to the delrin inside. The spanner wrench is also used to disassemble the Roto-Joint
for cleaning, inspection and rebuilding.
