About this part

Product Details

UMI Performance is known for building well-made suspension components right here in the USA. This rear shock tower brace is a prime example, designed to stiffen the chassis of your 1978-1988 GM G-Body vehicle. By tying the upper shock mounts together, it helps share the load and reduces flex, making a noticeable difference in how your car handles, especially during spirited driving or when cornering. It’s a popular upgrade for models like the Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, and Buick Regal.

This brace is built tough with 1-1/4” diameter tubing made from US Steel, MIG welded to laser-cut 3/16” thick brackets. UMI builds these on a jig to ensure a perfect fit, and they include Grade 8 hardware for a true bolt-in installation. You won't have to worry about clearance issues either; this brace is designed to work with most popular exhaust systems and fits equally well whether you're running traditional springs and shocks or a coilover setup. It comes powder coated for a durable, long-lasting finish.
