UMI Performance single adjustable panhard bars control the side-to-side movement of the rear-end under the vehicle. The flex and bushing deflection found with the factory panhard bars lead to erratic handling and tire rubbing under hard loads. Their tubular setup uses fluted polyurethane bushings, a heavy-duty spherical rod end, and is constructed from large 1.250 in. diameter tubing. Adjustable panhard bars are a must for rear-end centering after vehicle lowering, as well as clearance for running larger tires. The supplied rod end allows for adjustments off of the car to quickly lengthen or shorten the panhard bars. The spherical rod end/polyurethane bushing combination eliminates most rear-end bind, while not sacrificing your ride quality. They are excellent improvements for your street or drag application. Additional features include: * 1.250 in. x 0.095 in. mild steel tubing * Stronger and lighter then stock * TIG-welded construction * Greasable bushings * 4140 chromoly threaded tube adapters * 3/4 in. hard chrome plated PTFE/KEVLAR® self-lubricating race rod ends * Durable powdercoated finish
