The UMI Performance boxed lower rear control arm kit for 1968–1972 GM A-body offers a direct-replacement setup with reinforced sway bar mounting and heavy-duty laser-cut upper mounting pads. CNC-machined components and greaseable polyurethane bushings reduce bushing deflection while maintaining a factory look. Built from USA mild steel with a long-lasting powder-coat finish, the kit installs in approximately two hours with basic tools.
