Hoses should be fine with a body lift. None of the pressure plies have a barbed fitting, they should all be crimped. And those lines go from the engine (mounted on the frame) to the steering box (also mounted on the frame) so unless you have raised the engine, there is no affect of the body lift on the pressure lines. The reservoir to pump line can sometimes pull tight. You can either relocated the reservoir a bit lower on the fender ot slip the hose out on the barbed fitting a little. That one is not a pressure hose and should easy to get a longer one.
