UMI Performance 78-88 GM G-Body Rear Control Arm Kit Fully Boxed Lowers Adjustable Uppers

UMI Performance is known for making well-built suspension components for classic American cars. If you're working on a 1978-1988 GM G-Body, like a Buick Regal, Chevrolet Monte Carlo, or Pontiac Grand Prix, and want to dial in your rear suspension, this control arm kit is a solid addition. It's designed to reduce how much the suspension parts move around under load, which helps with sharper handling and can significantly cut down on wheel hop during hard acceleration.

This kit features fully boxed lower control arms. They're built from beefy 3-inch by 1-1/2-inch rectangular tubing and have CNC machined radius ends that are capped to keep dirt and debris out, giving it a clean, factory-like appearance. The upper control arms are where you get adjustability. They use heavy-duty CrMo adjusters and Teflon-lined rod ends, which allow for on-car adjustments. These rod ends act like solid bushings but still offer suspension articulation, reducing friction for better performance, especially during harder launches. The mounting pads on the upper arms are laser-cut from 1/4-inch thick steel and are designed to fit all rear end housings for this chassis.

Everything is MIG welded and finished with a durable powder coat. The kit includes greaseable polyurethane bushings with zinc-plated steel sleeves for longevity and easy maintenance. This kit is made in Philipsburg, PA, USA.
