This flagship suspension system represents the top tier of Fabtech’s Super Duty lineup, engineered for maximum articulation, increased wheel travel, and extreme durability. The advanced 4 Link front suspension design allows the axle to move freely through its full range of motion, greatly improving traction, control, and ride quality in demanding off-road conditions.
Massive 2-inch OD heavy wall 4 Link arms are paired with race-style 1-inch Uniballs to deliver exceptional strength and reliability under extreme loads. Heavy-duty 1/4-inch thick steel brackets securely mount the 4 Link system to the frame without cutting or welding, preserving factory frame integrity while ensuring long-term performance.
Front lift is achieved using Fabtech replacement coil springs that provide consistent ride height and controlled suspension movement. Supporting components including billet sway bar links, a track bar relocation bracket, and a drop pitman arm work together to maintain proper axle positioning, steering geometry, and predictable handling throughout the suspension travel.
Rear lift is accomplished using a combination add-a-leaf system and lift blocks with U-bolts, leveling the vehicle while maintaining load-carrying capacity and stable ride characteristics. This complete system delivers uncompromised off-road capability, strength, and confidence.
