UMI Performance 1964-72 GM A-Body Rear Lift Bars

UMI Performance lift bars replace your stock rear control arms, adding tremendous track gains, while not affecting ride height and keeping ride quality at its best. These lift bars are designed to work with axle torque to load the chassis of the car, forcing the rear wheels downward, while pushing the tires into the ground for harder launches and improved 60 ft. times. These bars are designed to greatly improve traction and reduce unwanted wheel hop. Constructed from boxed mild steel tubing, they feature a 0.120 in. wall and 0.188 in. thick mounting plates and are completely CNC-machined for exact tolerances and a superb fit. These lift bars feature greasable Energy Suspension bushings that reduce bushing deflection but still make these arms 100 percent streetable. Each lift bar features the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are placed in the correct pattern to maintain the sway bar level with the rear-end. All sway bar holes are reinforced with a 0.120 in. thick steel sleeve wall, TIG-welded, and then sanded into place. The rear mounting brackets feature two settings that allow the lift bar to be lowered 2 in. or 3 in., depending upon user preference and the vehicle's suspension setup. These lift bars also correct lost geometry and instant center on a lowered vehicle. Add a set of our adjustable upper control arms for maximum rear suspension setup!
