welcome to the site. Assuming by "axle flip" you mean putting the springs on top of the axles instead of underneath. (not actually flipping the axle over). I have gone the other way on jeeps to raise them, and on my travel trailer for more clearance as well. Not done the other way, especially on a big truck.
