STOP.
For ride quality issues, let's go "through it by the numbers".
1. Have you weighed each axle (corners better) and set tire pressure based on actual weight? Said another way, if your tire are over-inflated by 20 PSI, there is nothing you can do to make for a "smooth ride".
2. There are shocks that have the VAST majority of their dampening on extension (not on compression) so the ride is controlled, but ride is less harsh. Koni FSD shocks are an example.
I would start with those two before looking at air bags-- unless you have an axle that is at or over GVWR/ride height is below spec. If that is the case, indeed, start with a "lift" option, whether air bags, Sumo, etc.
