UMI Performance 73-77 GM A-Body Upper & Lower Control Arm Kit

The boxed lower control arms in this UMI Performance kit feature reinforced sway bar mounting holes, allowing for factory-style sway bar attachment. A shim is included to ensure the sway bar sits at its original height. The upper control arms are fixed length and come with heavy-duty, 1/4-inch thick laser-cut mounting pads designed to fit all rear end housings. These control arms are CNC machined for accuracy and assembled with greaseable polyurethane bushings, offering a durable and long-lasting solution for your 1973-1977 GM A-Body vehicle.

This kit is built to handle street driving, drag strip runs, or spirited corner carving. By minimizing suspension deflection, it contributes to a crisper handling setup and helps reduce wheel hop. The construction involves 1/8-inch wall thickness USA mild steel tubing, MIG welded heavy-duty bushing holders, and TIG welded sleeves that reinforce the sway bar mounting points. The entire assembly is finished with a durable powder coat for longevity. The greaseable polyurethane bushings come with zinc-plated steel sleeves, ensuring smooth operation and extended service life.

This control arm kit is designed to fit a range of GM A-Body vehicles from 1973-1977, including models like the Chevrolet El Camino, Oldsmobile Cutlass, and Pontiac LeMans. Installation is straightforward, typically taking about two hours with basic hand tools. The kit includes everything needed to upgrade your rear suspension for improved performance and handling.
