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

This is the UMI Performance 1-inch tubular rear sway bar, specifically designed for 1964-1972 GM A-Body cars like the Chevelle, GTO, and Skylark. If you're looking to improve your classic muscle car's handling, especially for pro-touring or performance street applications, this chassis-mounted sway bar is a solid choice. It works by reducing body roll during cornering, giving you a more stable and predictable feel when you're pushing the car a bit harder.

What sets this bar apart is its chassis and differential housing mount design. Unlike factory bars that can sometimes bind, these mounts are built to allow more freedom of movement, which means better performance. The bar itself is a lightweight 1-inch hollow tube, and it offers three distinct rates: one for street and auto-cross, another for road racing and strip use, and a third specifically for drag racing. You can adjust the pre-load for drag applications using the included hex adjuster, helping your car launch straight. The CNC machined mounts feature grip teeth and reinforcement gussets, and they attach to the crossmember with four 3/8-inch fasteners; drilling is required, but a template and instructions are included. The kit also includes premium greaseable polyurethane bushings and heavy-duty CrMo spherical rod ends with Teflon for smooth operation. UMI's system is designed to clear common rear ends like 10-bolt, 12-bolt, and 9-inch rears, and their CNC machined clamping system can accommodate axle tube diameters of 2.75, 3, and 3.25 inches. You'll want to verify your specific rear end's axle tube diameter before ordering.

This sway bar comes with a durable powder coat finish and includes high-strength 4140 CrMo zinc-plated u-bolts. While the primary installation is bolt-in, welding the chassis mounts is an option for added security. It's a well-built component designed to make a noticeable difference in how your classic GM handles.
