6" 2023-2026 Ford F450/F550 4WD (w/Diesel Engine) Dirt Logic 4.0 Coilover 4-Link Lift Kit by Fabtech

Fabtech’s K2432DL 4 Link Lift Kit for the Ford F450/F550 Super Duty delivers exceptional on-road handling while excelling in the most demanding off-road conditions. This advanced system is a bolt-on upgrade that replaces the factory Radius Arm suspension with a superior 4-link front suspension design. The kit includes all necessary components for a complete transformation, enhancing performance and durability.

This innovative lift kit minimizes caster change throughout the suspension travel, ensuring better on-road stability and handling. Off-road, the 4 Link design offers more articulation than Radius Arm systems, enabling superior terrain navigation at all speeds. The kit features Fabtech’s legendary Dirt Logic 4.0 resi coilovers, a track bar relocation bracket, a pitman arm, and more. For the rear, it includes a block and U-bolt kit to achieve a balanced lift. Tested and proven in over a decade of military applications, this system represents the pinnacle of Super Duty suspension engineering. Fabtech backs this product with a complimentary 5-year/60,000-mile powertrain warranty for added peace of mind.

Every component of this lift kit is expertly crafted in-house, featuring robust materials and precise engineering for long-lasting performance. The heavy-duty 2" OD link arms utilize 1/4" thick steel brackets with adjustable alignment cams for fine-tuning the caster at the new ride height. Fabtech’s patented 5-ton joints provide unmatched durability and a lifetime warranty. The Dirt Logic 4.0 coilovers boast a 4" diameter stainless steel body, a 1.25" NitroSteel piston rod, and remote aluminum reservoirs for consistent performance in the harshest conditions. These coilovers deliver 2" of additional wheel travel, combining off-road capability with on-road comfort.

Additional features include a 1/4" thick steel track bar relocation bracket to center the axle, a forged steel pitman arm for precise steering, and heavy-duty bump stop brackets to prevent suspension over-cycling. The kit also includes sway bar drop brackets, brake line relocation brackets, and steering stabilizer brackets, all of which are engineered for seamless integration and optimal performance. The rear lift block and U-bolt system maintain factory ride quality and load capacity while providing the necessary lift for the rear suspension. Fabtech’s 4 Link Lift Kit is designed for those who demand uncompromising quality and performance in their Super Duty suspension system.
