The UMI boxed rear lower control arm for 1965–1970 GM B-Body vehicles is a direct bolt-in replacement for weakened stamped factory arms. Constructed from 1/8" wall USA rectangular tubing with DOM bushing holders, it uses grease-able polyurethane bushings to reduce deflection, improve ride quality, reduce body roll and increase traction. Spring perches and clips accept factory or lowering springs. Optional Grade 8 hardware kit is available.
