There are 2 kits that may work on your particular 2021 Ford F-250 FX4. To determine if they will fit you will first need to measure from the top of your rear axle tube to the top of the jounce bumper pad. See included picture for measurements. You will need either 40mm, 70mm, or 80mm for either kit to work. I have also linked the installation videos below for both kits. Both kits were installed on FX4 package trucks.

First is the Firestone Ride-Rite Air Helper Springs # F35FV are rated for a maximum of 5,000lbs. These bags will hold 5-100psi. The Firestone product number is 2620.

The other option is the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs # F95FV. These are rated for 7,500lbs and will hold 5-150psi. The Firestone product number is 2712.

I recommend the Firestone Dual Air Command # F49VV as it is one of the only compressor systems capable of reaching the 150psi that the red label springs are capable of holding. It is also able to be controlled from the cab with the dual gauge controller. Allowing you to adjust your ride on the fly while you drive. With the on board compressor you can also air up tires on your truck or trailer.
