UMI boxed rear lower control arms for 1964–1972 GM A-body cars are a durable upgrade that reduce suspension deflection and wheel hop while retaining a factory-style look. Constructed from 2" x 1-1/2" rectangular tubing with reinforced sway bar mounting sleeves, they come with greaseable polyurethane bushings and a powder coat finish. CNC machined for accuracy, these arms install in about an hour using basic hand tools.
