First off, this is a great site. There are some awesome trucks out there. I've searched the forums, looked at the different manufacturers but can't seem to find a 4" body lift for my 2014 GMC Sierra 3500HD. Seems like I can do a 2.5-3" leveling kit or I've got to jump up to a 5-6.5" full lift. Am I missing something? I've looked at BDS, RC, Superlift, Zone. I'm a noob at this so any help/advice appreciated!
