lots of replies on here have never seen the ram air suspension.
its doing what its supposed to do. I have never owned one personally. I have heard some don't like it because the air bags allow the transfer of air from one bag to the other which can allow more sway.
I know
Hellwig Products released a sway bar for the factory air suspension. (and I have had to add a sway bar to every Ram 3500 dually I have owned for pickup camper usage)
I think you also have an alternative ride height selection that will lower the truck 1" which might bring that lower spring into play loaded.
