Wireless Air Bag Suspension Upgrade For 2025 Ford F-350 Super Duty With Tremor Package

Published 12/08/2025

Question:

I’m considering this wireless Firestone kit for my 2025 F-350, but my truck has the Tremor package. No lift kit added, but it does sit a bit higher. Will this still fit?

Mark, great question - the key is whether the rear suspension has been lifted. The Tremor package raises the front end, but it doesn’t add a rear lift according to my research, so in most cases the Firestone Air Bag Kit # F44XV is still a direct fit.

Firestone is very clear that this system only fits stock-height rear suspensions, and no spacer exists that will allow it to work on lifted trucks. But as I said, as long as the rear suspension is factory height and not leveled / lifted, you should be alright.

What do you plan to haul with that beefy truck? Whatever it may be, I think you'll like how you can adjust the suspension setting son the fly with only the app on your phone.
