You can clear 33s with a body lift. I've done it, but i don't recommend it being done again. Along with the body lift comes more body roll, your shift linkage likely wont work correctly anymore, your radiator will hang out from the bottom and look horrible because everything behind the body will stay in place, and its just not the best way to go... To clear tires sure, but save up a little, and clear the tires the best way with a suspension lift. In the end, that will treat you right in the long run.
