UMI Performance 78-88 GM G-Body 1in Tubular Rear Sway Bar Chassis Mounted Pro-Tour

UMI Performance is known for making well-built suspension components for classic American cars. This 1-inch tubular rear sway bar is designed for the 1978-1988 GM G-Body platform, fitting a range of vehicles like the Chevrolet Monte Carlo, Buick Regal, and Oldsmobile Cutlass Supreme. It's a multi-purpose bar built for serious performance, whether you're hitting the drag strip, an auto-x course, or the road race track.

What sets this bar apart is its chassis and differential housing mounting system. Unlike factory bars that can bind, these mounts are designed to reduce that bind, giving you more consistent handling. The bar itself is hollow and 1-inch in diameter, offering three distinct stiffness settings. You can select the longest hole for street driving, the middle for auto-cross or road racing, and the shortest for drag strip use, allowing you to tune the car's response. The CNC machined mounts feature grip teeth and reinforcement gussets, and they come with a hex adjuster for pre-loading the bar, which helps your car launch straight off the line. UMI includes a template and instructions for drilling the crossmember, and the bar is designed to clear a variety of rear ends, including factory and aftermarket options like Moser, Strange, and Currie. It uses heavy-duty, greaseable polyurethane bushings and race-style spherical rod ends with Teflon for smooth operation.

This sway bar is designed for a 100% bolt-in installation, though welding the chassis mounts is an option for added security. You'll need to verify your rear axle tube diameter, as it can range from 2.75 inches to 3.25 inches depending on the specific rear end and its manufacturing date. UMI includes premium greaseable polyurethane bushings and a billet steel hex adjuster for strength.
