Fabtech 19-20 Ford F450/550 4WD Diesel 6in 4Link Sys w/4.0 & 2.25 Dl

This Fabtech 6-inch 4 Link Conversion system is designed specifically for the 2019-2020 Ford F450 and F550 4WD Diesel models. You get everything needed to convert your front suspension to a 4 Link setup, including 2-inch OD heavy wall link arms with 1/4-inch thick steel brackets, adjustable alignment cams, and Fabtech's 5 Ton joints for the frame pivot. It also includes stout 1/4-inch thick steel frame brackets, Sway Bar Drops, a Trac Bar relocation bracket, a Pitman Arm, and a U-Bolt kit. The system is built to handle both demanding on-road driving and challenging off-road conditions.

The heart of this system is the Dirt Logic 4.0 conversion, featuring massive 4-inch diameter stainless steel bodies with 1.25-inch NitroSteel piston rods for excellent corrosion resistance and durability. These coilovers bolt directly into the factory coil bucket using 1/4-inch thick steel brackets. The system's geometry is carefully designed to reduce caster change throughout the suspension travel, which results in an improved highway ride. For off-road performance, the 4 Link setup offers more articulation than a traditional Radius Arm suspension, allowing your truck to tackle rougher terrain more effectively. The included American-made coil springs are built to handle the substantial weight of the F450 or F550 and contribute to a comfortable ride.

This system has been proven over a decade in consumer, commercial, and military applications, demonstrating its robust build and reliable performance. The 5 Ton joints, used in military applications for over 10 years, are known for being quiet and strong, ensuring an extended service life. By converting to this 4 Link system, you'll experience less caster change during suspension travel, benefiting your on-road handling, while gaining increased articulation for superior off-road capability.
