UMI Performance 64-72 GM A-Body Rear Coilover Kit Control Arm Relocation Bolt In

UMI Performance is known for making well-built suspension components for classic American muscle cars. This rear coilover bracket kit is designed for 1964-1972 GM A-Body vehicles, including popular models like the Chevrolet Chevelle, Buick Skylark, and Pontiac GTO. It lets you adjust your ride height, spring rate, and damping, giving you control over how your car handles for everything from drag racing to road course use.

The kit includes reinforced upper mounts that bolt directly onto the chassis, though you'll need to drill one additional hole for installation. The lower brackets attach to your stock rear lower control arm mounts, using the existing shock holes. Depending on your car's original setup, you might need to drill another hole there too. The two-hole trailing arm adjustment lets you fine-tune the instant center, which is key for optimizing rear-end behavior during launches or cornering. This kit is designed to work with stock GM axle housings and brackets.

Keep in mind that while this kit is a direct bolt-in for stock setups, aftermarket axle housings can vary significantly. Also, the rear shocks might interfere with some exhaust tailpipes, so check your clearance before installation.
