Skyjacker re-engineered the Super Dutys suspension via an impressive 4-Link Conversion. Replace your OEM radius arms with integrated radius arm drop brackets plus upper and lower adjustable control arms. Formed from 2-inch OD x 0.250 wall DOM tubing, both pairs of control arms are adjustable Flex Links. The adjustability allows proper caster settings to improve handling. Flex Links have a forked clevis end at the lower axle mount. The upper bracket mount has 1-1/4 in. forged rod end with steel encased rubber bushing. Drop brackets lower the rear mounts at the frame to maintain the correct caster specifications for proper alignment. Specifically engineered for Super Duty F350 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. Second Ride Rate stage engages after compression: resulting in a smoother ride. 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. Front sway bar links realign sway bar. Drop spacers reposition 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 and 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.
