Take your third-generation Ford Super Duty to new heights with Rough Country's 6-inch Radius Arm Coilover Conversion Suspension Lift. This all-inclusive kit lets you run up to 37-inch tires while preserving the smooth, factory-like ride you expect from your truck. Rough Country’s geometry-conscious design keeps suspension angles as close to factory as possible, delivering a stable, comfortable ride even with a substantial lift.
