You thought the notorious South Side Machine lift bars were done? Well, we brought them back! The UMI lift bars replace your stock control arms adding tremendous track gains while keeping your ride height the same and eliminating your quad shocks. 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 wheel hop. Constructed of boxed mild steel tubing, 0.120" wall and 0.250" thick mounting plates-completely CNC machined for exact tolerances and a superb fit. Lift bars feature grease able aluminum bushing with steel sleeves.
