I own a 06 2wd f150 screw and was wondering if I used the 2.5" leveling kit, will the drive be changed?

Thanks,

 

Very little, at least that is my experience with the same leveling kit.
I went from level with the 2.5 AS's, to lowered 3/5, back to leveled all within the past 18 months. The only thing I changed when going back to leveled is that I installed greasable ball joints as my originals were totally gone @ 25,000 miles with the AS's the first time....I am installing 315/70/17's this week...Just make sure you get an alignment after the install....
