doesn't work the same as a 2inch lift bro i have airbags in the back of mine witch yeah i lift the back up further than stock but if u don't change the suspension as well u don't get any more down travel in the back end .
also the airbags in the back if overloaded can cause some issues with the chassis bending
when i get my lift im going to take mine out as i don't really need them putting some heavy duty leafs in the back
you can can airbags like that, BUT are mostly if not always suited to solid axle trucks a mate of mine runs around with 6" lifts bags in a wrangler, he sets it at stock ride hieght around town and then jacks it up when 4wding
