I am considering an air only rear suspension for the rear of my 48 2 ton, no springs. But that will be a few years off yet. I'll test all my other modifications out on the new leaves I got last year, then think about air when I run out of other things to do to the truck. I'll be sure to have shocks then. I'll also keep the 16,000 pound GVW.
