Fabtech 17-21 Ford F250/F350 4WD Diesel 6in Rad Arm Sys w/4.0 & 2.25

If you're looking to significantly upgrade the suspension on your 2017-2020 Ford F-250 or F-350 Super Duty, especially if it's a 4WD Diesel model, this 6-inch Radius Arm Lift System from Fabtech is a robust solution. This system is designed to give your truck improved articulation and more wheel travel, making it more capable off-road and handling rough terrain with greater ease. It's a comprehensive package aimed at transforming your truck's stance and capability.

What sets this system apart are the heavy-duty components. The 2-inch diameter links are built with thick 1/4-inch steel brackets that bolt directly to the frame, meaning no cutting or welding is required for installation. The patented Radius Arms themselves feature a full tubular structure reinforced with dimple-die side plates, and they include an adjustable alignment cam at the axle for precise caster adjustment. This system also comes with everything you need to complete the transformation, including Sway Bar Drops, a Trac Bar relocation bracket, a Pitman Arm, and a rear Block and U-bolt kit. The inclusion of 4.0 front coilovers and 2.25 rear shocks means you're getting a matched damping system designed for this lift height.

When installing a lift kit of this magnitude, it's important to follow the manufacturer's instructions closely to ensure proper alignment and function. This Fabtech system is designed to integrate with your Super Duty's existing frame and axle components, providing a solid foundation for your truck's new suspension setup. It's a well-built package that addresses both form and function for serious Super Duty owners.
