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 for more ground clearance to work hard and play harder. Specifically engineered for Super Duty F350 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 flex\expand during full articulation as the suspension drops. 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. The sway bar links realign the front sway bar working angle to achieve maximum sway control. Drop spacers reposition the front bump stops. Front brake line brackets and braided stainless steel brake lines correct and reposition the brake lines. A heavy-duty steering stabilizer relocation bracket corrects and enforces the stabilizer connection. Hydro steering stabilizer included. Softride(R) Technology leaf springs have tapered leafs to distribute loads more evenly and to create more flex at the leaf ends. Teflon(R) wear pads between leafs and bolt style spring clips prevent binding and eliminate friction. Shocks are a key link in-between the chassis and your suspension. Front and rear damper capacity enhanced with ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. ADX 2.0 has a race-inspired full-displaced valving system. Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever. Together this complete kit maintains the factory geometry angles, alignment specifications and structural strength.
