Fabtech 17-21 Ford F250/350 4WD Diesel 4in Rad Arm Sys w/Coils & 2.25 Dl Resi Frt & Dl Rr Shks

If you're looking to give your 2017-2020 Ford F-250 or F-350 Super Duty a 4-inch lift, this Radius Arm System from Fabtech is a complete upgrade designed to handle both on and offroad demands. It's built to add strength for running larger tires and significantly improves upon the factory stamped radius arms with a robust tubular structure reinforced by dimple die side plates and heavy gusseting. This design has a proven track record, having been used in military applications for over a decade, ensuring reliable performance.

The heart of this system lies in Fabtech's tubular Radius Arms, which feature an adjustable alignment cam at the axle for precise caster adjustment. This kit replaces your stock suspension components with a properly designed geometry for improved handling. It includes replacement front coil springs for a 4-inch lift, a Trac Bar relocation bracket, a Pitman arm, sway bar drops, and a rear block and U-bolt kit. For damping, it comes equipped with Dirt Logic 2.25 stainless steel reservoir shocks up front and non-reservoir Dirt Logic shocks in the rear. These shocks are specifically tuned to work with the Fabtech coil springs and the intended oversized tire fitment, aiming for a comfortable and capable ride quality on and off the pavement.

This comprehensive system is a solid option for those needing enhanced capability and strength. Fabtech backs this system with a free 5-year, 60,000-mile powertrain warranty, offering added peace of mind with your investment.
