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

This is the Fabtech 6-inch 4-Link Conversion system specifically for the 2019-2020 Ford F450 and F550 4WD Diesel models. If you're looking to significantly upgrade your Super Duty's suspension for both demanding on-road driving and serious off-road adventures, this kit is built to handle it. It converts the front suspension to a 4-Link setup, which is designed to reduce caster change during suspension travel, leading to a more stable and comfortable highway ride. For off-road use, this geometry offers more articulation than a traditional Radius Arm setup, allowing your truck to tackle rougher terrain more effectively.

Fabtech has over 10 years of experience with this 4-Link system, proven in consumer, commercial, and even military applications. The system includes 2-inch OD heavy wall link arms with 1/4-inch thick steel brackets that attach to the axle with adjustable alignment cams. At the frame, they pivot using Fabtech's 5 Ton joints, which are known for their quiet operation, strength, and extended service life, having been used in military vehicles for over a decade. The kit also comes with stout 1/4-inch thick steel frame brackets, American-made coil springs that are preset to prevent settling and offer a compliant ride, and a track bar relocation bracket to keep your axle centered. This system is designed to work with Fabtech shock absorbers to increase wheel travel by 2 inches over stock.

This kit is a bolt-on system that doesn't require cutting or welding for installation. It includes everything needed to convert to the 4-Link system, such as sway bar drops, the track bar relocation bracket, a Pitman arm, and a U-bolt kit, along with the 4-link arms, brackets, and coils. The geometry is specifically engineered to provide an improved highway ride and better off-road capability compared to the stock radius arm setup.
