Why all of the sudden is the Truxx Leveling Kit I have installed sound like such a bad idea.

Don't be too alarmed NoCaDiver, remember that this encompasses all F-150's and all of their wheelbase configurations. It is only a guidline for technicians to use should a truck come in with a vibration concern related to the driveline. I doubt very seriously that you will encounter a concern with your levelling kit.
