How about 42's and 4" of lift. It works but you are going to rub the cab on severe flex. I cut my fenders and inners so that the inners start just below the lip where the cab floor meets the fire wall. I still have the inners and I think that it looks COOL with 42's. New truck is 6" with axle 1" forward and soon to be 44's. Will let you all know how it works in about 2 more weeks.
