Daystar Leveling Kits work within the factory suspension design, meaning that we work within the factory's design parameters to achieve an increase in ride height that levels the stance of the vehicle. Because we work within the factory's design, there are not a bunch additional modifications involved. Everything needed is included in the kit; there's everything you need and nothing you don't. If there are extra items required, such as longer shocks, it's clearly stated in the application description.
For use on 10.50" rear axle with 4" axle tubes.

You can call a local Ford dealer with your VIN number to verify your differential size. Most 05-14 Ford Super Duty's have the 10.5” differential in the rear. (Dually Super Duty's often have the Dana 80 in the rear.) You can physically measure the diameter of your axel tubes to be sure you have the 4" axle tubes. If you have any questions or issues, give us a call at 1-888-343-7354!
