I haven't been able to find a consensus sleuthing the world wide web on how much lift I need to clear 33x12.5R22's on 22x12 rims, likely with a -44 offset, but rims aren't purchased yet so that could change if need be. These will be going onto a 2004 Z71. I don't mind doing some plastic trimming but I have to run mud flaps for sure (drive some gravel) and I don't want a bunch of rubbing. I would prefer not to have to do the NorCal mod or a bunch of metal trimming if possible. I was looking at 4" Rough Country Suspension Lift and was hoping that would be enough to clear without going the full 6" lift route. Any help would be appreciated.
