This UMI Performance rear suspension kit replaces the factory stamped rear trailing arms and toe rod arms to help maintain rear caster and camber settings. Upgrading these components improves traction, helps eliminate wheel hop, and increases rear end stability. The arms are fabricated from 1 inch by 2 inch rectangular tubing with CNC machined mounting plates and bushing holders, and the kit is assembled with low-deflection, greaseable, fluted polyurethane bushings. It is a direct bolt-in setup that uses the factory hardware and typically installs in under two hours with basic hand tools. Made in the USA.
