I have a 2004 Denali and the whole air sus is pretty much the sucks. I'd like to convert it and be rid of the whole thing. I've looked up suspension kits online and a lot of them say (Exclude Denali). what good lifts are out there that would bolt right up. I don't wanna go more than 3 inches. Also right now I have a set of Falken Rocky Mountain 2s stock size but I'd like to go bigger and better. Any help would be appreciated. Thanks dudeys
