Fabtech 17-21 Ford F250/F350 4WD Diesel 8in Rad Arm Sys w/Coils & Dlss Resi Shks

If you're looking to significantly upgrade the suspension on your 2017-2020 Ford F-250 or F-350 Super Duty with a 4WD diesel engine, this 8-inch Radius Arm system from Fabtech is a robust solution. It's designed to handle demanding on and off-road conditions, offering a substantial strength improvement over the factory setup. The core of this system is Fabtech's tubular Radius Arms, which are reinforced with dimple die side plates and heavy gusseting, drawing from their racing experience to provide superior strength compared to stock stamped arms.

A standout feature of this 8-inch system is the extended-length Track Bar, which Fabtech developed to address the sensitive steering box in late-model Super Duty trucks. This unique, 4-inch longer track bar is offset to the driver's side and features a 1/4-inch thick steel mounting bracket. By bringing the Track Bar and Draglink closer to parallel than factory angles, it helps reduce steering 'push' and allows for full lock steering with up to 15.50-inch wide tires on 4.75-inch backspace wheels. The system also includes replacement coil springs for the front lift, a Track Bar relocation bracket, a Pitman arm, sway bar drops, and a rear block and U-bolt kit, along with their DL 2.25 inch reservoir shocks.

This comprehensive lift kit is built to enhance both the strength and performance of your Super Duty. Fabtech backs this system with a free 5-year, 60,000-mile powertrain warranty, giving you added peace of mind. The Radius Arms themselves feature an adjustable alignment cam at the axle for caster adjustment, ensuring proper alignment after installation.
