I am interested in adding a little height to my 06 F250 4x4. I have been reading about the leveling kits so I wanted to see if my front end was lower. I parked it in the garage to get a level surface and the front ends measures about 39.25 inches from the floor to the middle of the fender and the back measures about 40.5 from the floor to the middle of the fender. Does this sound right? If so then this leads me to believe that a 2.5 leveling kit would make the front end too high. Wanted to also say that my truck has a camper towing package on it if that makes a difference.
