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

If you're looking to give your 2017-2020 Ford F-250 or F-350 Super Duty Diesel a significant suspension upgrade, this 4-inch radius arm system from Fabtech is a solid option. It's designed to bolt directly onto the frame without requiring any cutting or welding, making installation more straightforward. This kit aims to provide better articulation and more wheel travel than the stock setup, which is great for off-road use or just handling rougher terrain.

The heart of this system is Fabtech's patented radius arms. They're built with a full tubular structure and reinforced with dimple-die side plates for added strength. At the axle end, you'll find an adjustable alignment cam, allowing you to fine-tune your caster for proper wheel alignment after the lift. The system includes heavy-duty 2-inch diameter links with 1-inch Uniballs for superior strength and durability. You also get replacement 6-inch front coil springs to achieve the 4-inch lift height, along with a Trac Bar relocation bracket, a new Pitman arm, and sway bar drops to correct suspension geometry.

To complete the setup and ensure a balanced stance, this kit also comes with a rear block and U-bolt kit. To top it all off, it includes front and rear performance shocks designed to work with the new suspension components. This comprehensive kit is designed to give your Super Duty a more aggressive look and improved on and off-road capability.
