UMI Performance 64-72 GM A-Body 1-3/8in Tubular Rear Drag Sway Bar-Bolt-on

Starting with a 1-3/8 inch diameter tubular steel bar, this rear drag sway bar from UMI Performance is built to help your classic GM A-body launch hard and stay straight. It's designed to reduce body roll significantly, keeping your car planted during aggressive acceleration. This bar is made in the USA and comes in your choice of red or black powder coat for a durable finish.

This sway bar offers three distinct rates, allowing you to tune it for different setups, whether you're running street tires, drag radials, or full slicks. The CNC machined clamping system is designed to fit axle tubes from 3 inches to 3.25 inches in diameter, accommodating factory 10-bolt and 12-bolt rears, as well as common aftermarket options like Moser, Strange, and Currie. It features heavy-duty aluminum mounts with greaseable polyurethane bushings and ultra-premium CrMo spherical rod ends with Teflon races for smooth, reliable operation. The integrated hex adjuster allows for on-car pre-loading, which is crucial for drag racing to ensure your car leaves the line straight, no matter how much power you're putting down.

Installation is designed to be a bolt-in process, though UMI recommends welding for added security, especially given the forces involved in hard launches. Drilling through the crossmember is required, and a template and instructions are included to guide you. This sway bar is a solid option for anyone looking to improve their classic GM A-body's stability and launch characteristics.
