UMI Performance carrier bearing relocation kits adjust driveline angle to reduce or eliminate vibration caused by lowering the 2015+ Ford F-150 (trucks with a 2-piece driveshaft). Each shim and clamp kit comes complete with 1/4 in. thick shim, reinforcement plate, and proper hardware. Installation is accomplished by removing the factory carrier bearing mount and substituting with one of these shim kits. This ensures the proper driveline angle and delivers a supremely smooth driveline. The steel brackets are finished with a tough black powdercoat. Cutting of factory mount is required.

UMI Performance on-car 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 bar lead to erratic handling and tire rubbing under hard loads. UMI Performance on-car single adjustable panhard bars use polyurethane bushings and a heavy-duty spherical rod end and are 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 on the car to quickly lengthen or shorten the panhard bars--they do not need to be removed to make adjustments. The spherical rod end/polyurethane bushing combination eliminates most rear-end bind, while not sacrificing your ride quality. These panhard bars are an excellent improvement for your street or drag application and they are also lighter then the factory panhard bars!
