The Superpro rear leaf spring shackle bushing kit for 2009–2014 Ford F-150 stabilizes rear axle movement on 4WD trucks by replacing worn OE rubber bushings. These bushings reduce rear axle shift that can cause wandering and passive steer under braking or when towing, improving stability when carrying loads and restoring intended axle control compared with degraded components.
