Air bags in rear also?
Is it hitting the bump stops? Are shocks bottoming out?
Put some tape or paint or wire ties around things or a remote camera and find out how far the suspension is traveling over normal driving. If it gets into the stops or bottoms out, it is going to go from soft to jolting real fast...
Or if air bags are just too stiff and the suspension isn't moving at all, talk to air bag manufacture.
