This kit includes both the upper and lower rear control arms designed to easily bolt a 1964-1972 GM A-Body 10-Bolt or 12-Bolt rear end into a 1978-1988 GM G-Body, which includes models such as Monte Carlo, Malibu, El Camino, Regal, Grand National, Grand Prix, and Cutlass. The upper control arms included in this kit are specially designed to correctly attach to the G-Body chassis and A-Body rear end "ears". These control arms are essential for a successful swap and should always be used. Using factory upper control arms can result in rear end bind, incorrect driveline angle, traction loss, vibrations, and unsafe handling. The lower control arms are of fixed length and help center the rear end in the wheel wells. Additionally, the lower arms are equipped with grease-able polyurethane bushings and reinforced sway bar holes for added durability and performance.
UMI rear control arm kit lets you bolt a 1964–1972 A-Body rear into a 1978–1988 G-Body. Includes upper and lower arms designed to prevent bind, correct driveline angle, and improve handling with greaseable poly bushings and sway bar mounts.
