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

Starting with a 1-inch diameter hollow tubular steel construction, this rear sway bar from UMI Performance is built for serious handling improvements on your 1978-1988 GM G-Body. It's designed to tackle a range of driving styles, from street cruising and autocross to road racing and drag strip use, offering three distinct rates to match your needs. The key to its performance lies in the chassis and differential housing mounts, which work together to significantly reduce the binding often found in factory sway bar setups. This means more consistent handling and better tire contact with the road, especially during aggressive maneuvers.

UMI has engineered a CNC-machined clamping system that accommodates various differential housing diameters, including 2.75-inch, 3-inch, and 3.25-inch, making it compatible with many common rear ends like the factory 7.5, GN 8.5, 12-bolt, Moser 9-inch, and others. Installation can be a bolt-in affair, though welding the mounts offers additional security for high-performance applications. The kit includes heavy-duty CrMo spherical rod ends with Teflon races for smooth operation and a billet steel hex adjuster that allows you to pre-load the bar for drag racing, ensuring your car launches straight. The double shear chassis mounts attach to the crossmember with four 3/8-inch fasteners, and a template is included to guide you through the necessary drilling.

This sway bar is a well-built upgrade for enthusiasts looking to dial in their G-Body's suspension. It features greaseable polyurethane bushings for longevity and a durable powder coat finish. While drilling into the crossmember is required for the chassis mounts, the rest of the installation is designed to be straightforward, especially if you're familiar with suspension work. This bar is a solid option for anyone looking to improve their vehicle's cornering ability and stability.
