What is the main benefit of installing these rear lift bars?

These lift bars are designed to improve rear suspension traction. By working with axle torque, they help load the chassis, pushing the tires down for harder launches and reduced wheel hop, which can lead to better 60-foot times.

Does this kit include everything needed for installation?

The kit includes Grade 8 mounting hardware and detailed installation instructions. However, this is a weld-in setup, and the mounting brackets are supplied bare metal, meaning you will need welding equipment and expertise to install them.

Can I adjust the ride height with these lift bars?

While these lift bars are primarily for improving traction, the rear mounting brackets feature three settings that allow you to adjust the lift bar position by 2", 2-3/4", or 3-1/4". This adjustment can help correct suspension geometry, especially on lowered vehicles.

Product Details

If you're looking to get more out of your classic GM A-Body's rear suspension, UMI Performance's weld-in rear lift bars are a solid option. These aren't just about lowering your car; they're designed to work with your axle's torque to load the chassis, pushing the rear tires down harder for improved launches and better 60-foot times. They're built to help reduce unwanted wheel hop, giving you more consistent performance off the line. This set-up fits a wide range of popular vehicles like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark from 1964 through 1972.

These lift bars are constructed from boxed mild steel tubing, with 1/8" wall thickness for the tubing and 3/16" for the mounting brackets, making them well-built for the task. They feature greaseable polyurethane bushings that help reduce deflection while still being streetable. You'll also find reinforced sway bar mounting holes, which are TIG welded with steel sleeves for added strength and proper sway bar alignment. The rear mounting brackets offer three different settings, allowing you to adjust the lift bar position by 2", 2-3/4", or 3-1/4", which is useful for correcting suspension geometry on lowered vehicles. The kit comes with Grade 8 hardware and detailed instructions, but remember, this is a weld-in setup, and the brackets arrive bare metal, ready for you to weld them in place.
