Not necessarily. The specs will have some degree of tolerance based on the frame angle. Some of the older manuals used to have a chart in them showing what the camber/caster should be set at for a given frame angle as well as changes in ride height. With the new equipment, the computer does that for you. Now, if you had a printout of how the truck sat before the tires/frame angle was altered, and compared it to the printout that you have, you would most likely see a difference, mainly in the caster reading.
