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

This is the Fabtech 6-inch Radius Arm lift system specifically for your 2019-2020 Ford F450 or F550 4WD Diesel. If you're looking to upgrade your Super Duty's suspension for more aggressive off-road use or to fit larger tires, this kit is designed to handle those demands. The F450 and F550 have a more robust suspension than their F250/F350 counterparts, and this system provides the necessary strength and geometry changes to accommodate a 6-inch lift.

Fabtech has proven this Radius Arm design over a decade in various demanding applications, including commercial and military use. The tubular radius arms themselves 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 come with 1 degree of caster built-in, and adjustable alignment cams allow for an additional 1.5-2 degrees of caster adjustment, which is crucial for proper alignment after lifting. The included American-made coil springs are preset to prevent settling and are designed for a comfortable ride, allowing for an increased 2 inches of wheel travel when paired with the included Fabtech performance shocks. A stout, box-style track bar bracket is included to properly center the front axle under the lifted vehicle, and a forged steel dropped pitman arm ensures correct steering linkage geometry.

This kit is a comprehensive upgrade to your factory suspension, offering improved strength and geometry for larger tires and tougher terrain. It's designed to integrate with your truck's existing setup while providing the robust performance needed for serious work or play.
