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

These lift bars are designed to improve rear-end traction and reduce wheel hop. By working with axle torque, they help load the chassis and push the tires into the ground, resulting in harder launches and potentially improved 60-foot times.

Do I need to weld or drill to install these lift bars?

For street applications, these lift bars feature a bolt-in design that requires no drilling, welding, or cutting. However, welding is recommended for vehicles that will be used with drag radials or slicks for added security under race conditions.

What is included with this lift bar kit?

The kit includes the rear lift bars, mounting hardware, and installation instructions. It also features greaseable polyurethane bushings and provisions for adding a sway bar.

Product Details

Starting with boxed mild steel tubing, 1/8" thick wall, and 3/16" thick mounting brackets, these UMI Performance rear lift bars are built solid for your classic GM A-Body. They replace your factory rear control arms to help put power down more effectively, aiming to improve your 60-foot times and reduce that frustrating wheel hop. This kit is designed as a true bolt-on, meaning no drilling, welding, or cutting is required for street applications, making installation straightforward.

These lift bars work by using axle torque to load the chassis, forcing the rear wheels down and pushing the tires into the pavement. This action is key for harder launches. The greaseable polyurethane bushings are well-built to reduce deflection while still being streetable. You'll also find provisions for adding a stock or aftermarket sway bar, with reinforced holes that keep the sway bar level. The rear mounting brackets offer three settings, allowing you to adjust the lift bar angle by 2", 2-3/4", or 3-1/4", which helps correct geometry on lowered vehicles. For the ultimate rear suspension setup, UMI suggests pairing these with their adjustable upper control arms.

This kit fits a wide range of classic GM vehicles, including models like the Chevrolet Chevelle, Buick Skylark, and Pontiac GTO. It comes complete with mounting hardware and installation instructions. While designed as a bolt-in for street use, welding is recommended for vehicles running drag radials or slicks to ensure maximum security under extreme conditions.
