We sure do Susie! To add a set of air bags to your 2021 Ford Transit 350HD Ecoboost dual rear wheel van, you'll need the Firestone item # F2603. These air bags have a 5,000 lbs capacity that will level out the rear end of your Transit 350 and smooth out your ride. This kit comes with custom fit mounting brackets and all hardware to complete the installation is included.

I linked the installation instructions below for the Firestone item # F2603 air bags. There is a section on page 7 where you may have to drill 1/2” hole for the brackets depending on whether or not your Transit already has the holes there.

I also recommend adding the Firestone Air Command item # F2610 to your setup. This onboard compressor will allow you to adjust the PSI in your air bags from your phone.

What do you haul around in your Transit?

I’ve done a camper conversion. It’s a full build and I’m pretty heavy. I want to be able to adjust each side individually and have an air hose available in the back. And yes I want wireless control. I appreciate your response. Thank you, Sisie

@Susie You're welcome! That sounds like a fun build! The Firestone Air Command Heavy Duty Air Compressor item # F99VV is the one you'll need then. It's a dual path compressor so you'll able to adjust the PSI in the air bags individually. It's controlled through the Firestone app and comes with a 30' long coiled air hose with a tire inflator fitting.
