Anybody have any experiences or opinions on lifts for the 2011+ 2500 gm? I'm running a levelling kit right now and can't stand the ride. Looking at putting on a lift kit instead to get some ride back. Haven't heard anything bad about the Zone 5". Don't want to go any bigger as its just a 6.0l. Will be driving probably 70/30 highway/back roads with sleds or quads on the deck.
