I started out with airbags. They just made the ride worse with lots of sway. To help with the sway I set my Rancho shocks on high for the rear and close to high in the front. The ride was stiff and jarring but at least the sway was somewhat tamed. I kept dropping the pressure in the airbags until finally I was not using them at all.
I then added super springs. That cut back substantially on the sway. At that point I lowered the settings on the Ranchos and the ride has been comfortable.
My situation may not match yours since I have a SRW axke but I would suspect your shocks are too stiff. With a DRW I doubt you need to do anything with the suspension besides softer shocks.
