Up your control and raise your Super Dutys off-road performance abilities. Gain ride height and improved ride quality with this 4-inch lift. Get some aggressive 35s off-road tires for more ground clearance to work hard and play harder. Specifically engineered for Super Duty F250 4WD Diesel motors, these 2-Stage Variable Rate Springs deliver a smooth controlled comfortable ride. First Flex Rate stage delivers a comfortable ride with the ability to flexexpand during full articulation as the suspension drops (full droop). Second Ride Rate stage only engages after compression past Flex Rate: resulting in a smoother ride. Radius arm drop brackets lower the OEM radius arms mounts at the frame to maintain the correct caster specifications for proper alignment. An ultra heavy-duty track bar relocation bracket captures the front crossmember on both sides to prevent movement in this critical high-stress area and to keep the axle centered.
