Product Details

If you're looking to get the most out of your 1978-1988 GM G-Body's rear suspension, this tubular upper and lower control arm kit from UMI Performance is a solid option. Stock control arms can suffer from bushing deflection and rust, which hurts traction and handling. This kit replaces those weak points with well-built tubular arms designed to improve your car's performance, whether it's a weekend cruiser or sees track time.

These arms are constructed from 1.625" OD x 0.120" DOM mild steel tubing and are fully TIG and MIG welded for strength. They come with high-quality polyurethane bushings that offer a noticeable improvement over stock rubber, helping to reduce traction loss and wheel hop. The lower control arms even include mounting holes for your stock or most aftermarket sway bars. Installation is straightforward, as they are designed as a direct bolt-on replacement using your original hardware.

This kit is a great way to enhance your G-Body's cornering ability and track consistency. UMI Performance offers a durable powder coat finish to help these arms last.
