I know that there is a topic about these just asked ( great info thebenagade, thanks). My question is, do the airbags help with basic sagging? Here's my problem, I've disco'd my rear sway(have had off for sometime, only gets fishy on hwy big gust of wind, but I know that's a whole nother forum) haven't installed pucks for bumpstops yet. I was out crawlin the other day and almost tore off pass. rear fender, now seems like any little flex I do I'm shoveing my rear pass. tire into fenderwell( being disco'd in front as well). My Rustys springs don't look like they are sagging but are wondering if airbgs will give a bit of lift. I've already got extra iso on top of spring and don't do much towing or hauling heavy stuff in Libby, so would airbags be a waste of money in my case?
