Application
- 2023–2025 Ford F-250 Super Duty XL, XLT, Lariat, King Ranch or Platinum; diesel, 4WD, single rear wheel, with compatible 2.5-inch, 4-inch or 6-inch Fabtech suspension. Verify installed suspension and vehicle equipment before ordering.
- Does not fit gas engines, dually trucks or vehicles equipped with Ford onboard scales. F-350 and 2026 applications are outside this listing.
Package contents
- One FTS22390 box containing TWO complete radius-arm assemblies: driver upper/lower sections FT31120/FT31122 and passenger upper/lower sections FT31121/FT31123, with two rod ends, specified misalignments and installation hardware. These four sections form two arms.
- Radius arms only. Springs, shocks, rear lift components, wheels and tires are not included. This component kit does not itself set the vehicle lift height.
Installation and requirements
- Professional installation required. Read FT22390i and the instructions for the complete installed Fabtech suspension before work. Use the compatible Fabtech shocks required by the instructions.
- Support the axle, remove the factory arms, and remove any previously installed radius-arm drop brackets as directed. Install with the supplied frame hardware and retained factory axle hardware.
- The adjustable arms arrive preset. Check front alignment for the installed lift, check brake-hose, ABS-wire and tire clearances through steering travel, adjust headlights and recheck all fasteners after 50 miles and periodically.
Tire and wheel guidance
- Fitment and tire clearance depend on the complete installed suspension and wheel combination. This arm-only kit is not a guarantee of clearance for a particular tire size.
