Does Firestone Ride-Rite Air Suspension Kit Fit 2025 Ford F350 Super Duty FX4 Dually?

Question:

Will this F44XV kit fit my 2025 F-350 FX4 dually? I’m worried about the extra width and suspension differences.

Carlos, you’re all set - the Firestone Ride-Rite Air Bag Suspension Kit # F44XV fits 2025 F-350 single rear wheel and dual rear wheel models, in both 2WD and 4WD configurations. Dually width doesn’t affect air-bag fitment at all.

For FX4 trucks though, just check the one measurement Firestone calls out:
Measure the distance from the top of the rear axle to the bottom of the bump-stop bracket. If it lands at 40mm, 70mm, or 80 mm, the kit fits. Also make sure there is no level/lift kit on the back axle since that would go against fitment. Front level/lift is fine.

If you need anything else or have any follow up questions/comments, you know where to find me!
