Fabtech 19-20 Ford F450/550 4WD Diesel 6in 4Link Sys w/Coils & Stealth

Starting with the 2-inch diameter heavy wall link arms, this Fabtech 4 Link Conversion system for your 2019-2020 Ford F450 or F550 4WD Diesel is built to handle serious on and off-road demands. These link arms feature 1/4-inch thick steel brackets at the axle with adjustable alignment cams, and pivot at the frame using Fabtech's proven 5 Ton joints. These joints have a long history of use in military applications, offering a quiet and strong pivot point for an extended service life.

The geometry of the 4 Link arms and the stout 1/4-inch thick frame brackets has been carefully designed to reduce caster change during suspension travel. This results in an improved highway ride compared to stock, while also providing more articulation off-road than a traditional radius arm setup. This means better terrain traversing capabilities at all speeds. The system includes American-made, preset coil springs designed for a compliant ride quality and to prevent ride height settling over time, allowing for a 2-inch increase in wheel travel when paired with Fabtech Stealth shocks. The kit also includes a 1/4-inch thick steel bracket to reposition the factory track bar, centering the axle under the chassis.

This complete bolt-on system comes with everything needed to convert your front suspension, including Sway Bar Drops, the Trac Bar relocation bracket, a Pitman Arm, and a U-Bolt kit. It's designed to integrate with your Super Duty's robust suspension, offering a significant upgrade in both on-road comfort and off-road performance.
