With an 06 you may be left a little nose high. If that is the case and you don't like it an aal or larger rear block will bring up the rear. My 06 with 2 inch autospring sits level.

I may be wrong, but I think the FX4 will be perfectly level because the FX4 has a little more rake than the lariat or XLT. I have an 05 FX4 with a RC 2.5" level and I am perfectly level. Plan on getting the BDS 6inch within the next few months tho. It's time.
