I have a NBS 07 model GMC crew cab. I want to get it leveled out and put a size or two larger tires on it then it came with stock. I don't want it to look out of place like the tires are to big and it needs lifting hgiher if that makes sense. Will a 305 be to large on the truck with just a leveling kit in the front? what do you guys run on yours? Pics would be nice if you have any. Thanks!
