Lift kit for Sierra

I have a 2011 half ton gmc Sierra, crew cab, z71 with 33 nitto terra grapplers. I want to get a 4" lift kit package but I am not sure which route to take. I want something that will make for a smooth ride while having a good quality lift. I travel a lot of oilfield roads and they can sometimes be atrocious. I don't want to have to do any cutting either, just a bolt on setup. Any advice/ideas?
