Minimize wheel  hop and increase rear end stability on your Pontiac G8 with a set of UMI  Performance trailing arms. These heavy duty trailing arms replace the factory  stamped arms reducing flex and bushing deflection resulting in a more  controllable vehicle. UMI’s trailing arms are fabricated from 1” x 2”  rectangular tubing and feature ¼” thick CNC machined mounting plates. They are  assembled with fluted, greaseable and low deflection polyurethane bushings from  Energy Suspension. Trailing arms are a direct bolt in and installation time is  less than an hour using basic hand tools.
