That's a good question, and the difference between the two Firestone Ride-Rite air bags that fit your 2019 Ford F-350 4x4 is that one kit is designed to kit models with single rear wheels and the other is designed to fit models with dual rear wheels:
- Single Rear Wheels: Firestone Ride-Rite Air Helper Springs # F89ZR
- Dual Rear Wheels: Firestone Ride-Rite Air Helper Springs # F88ZR
The mounting brackets for the air bags are different to accommodate for the different configurations. Apart from that, the Ride-Rite are the same in terms of construction and quality, as the Firestone air bags are easily the best quality for your F-350. The reason for that is they are made from four layers of reinforced rubber, which is a thicker, more reliable construction than other air bags which have just two layers of rubber.
The only other thing I highly recommend is adding a compressor to make both monitoring and maintaining the air bags on your F-350 much easier and from the comfort of your cab. The best option to do so is a wireless compressor that allows you to use an app on your phone to control them, the Air Command Compressor System - Wireless # F2610.
Then to mount it you can use the No-Drill Mount Kit for Firestone Air Command # F2612.
