78-87 G-Body Rear Lift Bar Set

The UMI Performance lift bars replace your stock rear control arms adding tremendous track gains while not effecting ride height and keeping ride quality at its best. 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-foot times. These bars are designed to greatly improve traction and reduce unwanted wheel hop. Constructed of boxed mild steel tubing, 0.120" wall and 0.188" thick mounting plates-completely CNC machined for exact tolerances and a superb fit. Lift bars feature grease-able Energy Suspension bushings that reduce bushing deflection but still make these arms a 100% street-able. 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” wall thickness steel sleeve TI
