Fabtech 19-20 Ford F450/F550 4WD Diesel 6in Rad Arm Sys w/Coils & Stealth

If you're looking to give your 2019 or 2020 Ford F450 or F550 4WD Diesel a significant suspension upgrade for both on and offroad adventures, this 6-inch Radius Arm lift kit from Fabtech is a solid option. These trucks have a more robust suspension than their F250 and F350 siblings, and this kit is specifically designed to meet those demands, offering improved strength for running larger tires and handling tougher terrain.

This system replaces the factory suspension components with well-built parts designed for durability and performance. The tubular radius arms feature a dimple-die side plate for added strength and are offset to ensure you have full turning radius even with wide tires. They also include 1 degree of built-in caster for the increased ride height, with adjustable alignment cams that allow for an additional 1.5-2 degrees of caster adjustment. The included American-made coil springs are preset to prevent settling and are designed for a comfortable ride, potentially increasing wheel travel by 2 inches when paired with Fabtech shocks. A stout, box-style track bar bracket made from 1/4-inch thick steel repositions the factory track bar to keep the front axle centered under the vehicle. A forged steel dropped pitman arm is also included, engineered to work with the factory steering on these heavy-duty trucks.

This kit has a design proven over 10 years in various demanding applications, from consumer use to commercial and military vehicles. It's a comprehensive upgrade that focuses on proper suspension geometry and high-quality components to set it apart. When installing, you'll want to refer to the manufacturer's instructions for specific details on alignment adjustments and any other necessary steps to ensure optimal performance and safety.
