IThe only thing which isn't perfect is that you need to always keep 5 psi in them to keep their shape. Otherwise they could get pinched between the spring or whatever. So this 5 psi raises the rear end a tiny bit when the truck is empty. But it's rarely empty, so it doesn't matter that much. I think it's only about 1 cm anyway......


I think this is common with most air bags, but I am not an expert.
