Fabtech 2023+ Ford F250/F350 4WD Super Duty 2.5in/4in/6in FTS-X Adjustable Radius Arm Box Kit

With this Fabtech FTS-X Adjustable Radius Arm Box Kit, you get a direct replacement for the factory radius arms on your 2023-2025 Ford F-250 Super Duty 4WD. This kit is designed to work with 2.5-inch, 4-inch, and 6-inch lifted suspension systems, offering a way to fine-tune your front-end alignment after lifting your truck.

The core of this system is the FTS-X adjustable radius arms. These arms feature an adjustable lower link, which is a key feature for eliminating binding in the suspension as it articulates. More importantly, this adjustability allows you to set a preferred caster profile. Proper caster is crucial for steering stability and returning the steering wheel to center after a turn, especially on lifted vehicles where factory geometry is altered. By replacing the stock arms with these adjustable units, you gain the ability to dial in your alignment for optimal on-road manners and handling.

This kit is a solid option if you're installing a 2.5, 4, or 6-inch lift on your Super Duty and want to ensure your caster is set correctly. It's designed as a direct bolt-on replacement, meaning no welding or cutting is required for installation, making the process more straightforward.
