UMI Performance's boxed rear control arm kit for 1968–1972 GM A-body replaces weak stamped components with fully boxed lowers and fixed-length upper arms. Reinforced sway bar mounting holes accept factory-style bars, and the upper mounting pads are heavy-duty laser-cut steel. CNC machining, greaseable polyurethane bushings and a durable powder-coat finish improve accuracy and longevity. Installation takes about two hours using basic hand tools.
