It's a good idea to ask for a recommendation because the FX4 models can be tricky as there are a number of kits that do not fit, and dually trucks also have their own applications. And the best air bags are going to be from Firestone because they are made with four layers of reinforced rubber, which is a thicker and more durable construction than other air bags, which have just two layers. This means, particularly when towing a 5th wheel trailer, you will get the best support possible for your truck's suspension.

The correct fit for your 2020 Ford F-350 FX4 dually with 4-wheel drive is one of the following:

- 5,000 lb Capacity: Firestone Ride-Rite Air Helper Springs # F35FV


- 7,500 lb Capacity: Firestone Ride-Rite Red Label Air Helper Springs # F95FV

With your hitch weight being pretty hefty I recommend going with the 7,500 lb capacity Ride-Rite # F42ZR to maximize the support your F-350 gets.

Additionally, you are going to want to ensure your air lines are cut perfectly straight during the install, and the best way to do this is by using the Air Hose Cutter # AL10530.

To make it easier to maintain the air bags I also highly recommend a compressor, so you can adjust and monitor the air pressure in each bag from the comfort of your truck's cab. For this you will need the Firestone Air Command II - Analog Gauge w/ Heavy Duty Compressor # F2219.

The compressor can be mounted to your F-350 with the Universal Mount Kit # F2497.
