it sounds like you must have over load springs, that work as the truck body drops the springs come into contact with the overload spring perches on the frame.
Your not loaded enough to make them come into play full time so they BANG every time the springs hit them
As you crank up the air bags they you are raising the back so they never hit again.
on my Ram I replaced the rubber spring perch mounts with larger poly ones made by Energy Suspension. they are taller so they come into play sooner, but with those slots in them they need to crush as the weigh increases and it stopped the banging but did not affect the ride.
Torklift Upper stable loads so the same thing, but they are harder and will not crush as they come into play.
some have used hockey pucks mounted on spring perches as well.
I sold my 2006 to my Brother and he still has the same pair on for 125,000 miles. I had them on my 2015 as well.
