The lift kit lifts the body by the stated amount - increasing you body height in addition to the "tire lift" so when I get 2.5" lift the bottom of my body will be higher by 2.5" given by the lift kit + 2" from the tires by a grand total of 5.5" but those 5.5" are mostly helping when straddling obstacles like rocks and logs, my pure ground clearance is still only 2" bigger than before. I leave out the discussion about effect of the suspension/body lifts on the articulation and vehicle's ability to clear much bigger obstacles - ground clearance is still the ability to "clear" or ride over obstacles between the wheels on flat surface.

P.S. Guys I am not trying to start a flame war here
