You can run 33's on the truck with the stock suspension unless the tires are really wide and not on factory rims. I'm going to 275/75/18's soon, they are 33.2" and I won't have any issues.
I don't care for the front leveling unless the rear is lifted too. To me it looks like someone started lifting the truck and only had enough money to do the front half and plan to do the back later.
