UMI Performance 64-72 GM A-Body 1in Tubular Rear Sway Bar Chassis Mounted

UMI Performance is well-known for making solid suspension components for classic muscle cars. This 1-inch tubular rear sway bar is designed for the 1964-1972 GM A-Body platform, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. It's built to reduce the binding often found in factory sway bar setups, which can really help improve how your car handles, especially during spirited driving or on the track.

This isn't just a simple bar; it's a Pro-Tour style setup that mounts to both the chassis and the differential housing. This dual mounting point is key to minimizing bind. The bar itself is a lightweight 1-inch hollow tube, CNC bent for precise fitment. It offers three distinct rates: a softer setting for street driving and autocross, a middle setting for road racing and strip use, and a stiffer setting for drag racing. The included hex adjuster allows you to pre-load the bar for drag applications, helping your car launch straight. The chassis mounts use four 3/8-inch fasteners, and while drilling the crossmember is required, a template and instructions are included. The differential mounts are CNC machined with grip teeth and reinforcement gussets, and they're designed to fit a range of axle tube diameters (2.75", 3", and 3.25") and clear common rear ends like 10-bolt, 12-bolt, and 9-inch rears. It also features premium greaseable polyurethane bushings and heavy-duty CrMo spherical rod ends with Teflon for smooth operation.

This sway bar is designed for a 100% bolt-in installation, though welding the differential mounts is an option for added security. It's a well-built piece that can make a notable difference in your vehicle's cornering ability and stability.
