I believe it's a 6" lift, but I also trusted the person I got the lift off of craigslist that the leaves were for a ranger... they weren't. having the good drop bracket for the passenger beam I'm not upset though as it was still cheaper than new.
I think it's about 6 or 7" lift total in the front, and yes, that's the beefy FA600 pitman arm, yes there is a lot of $$ under my truck... I din't measure height before and after, I just knew it should have been enough for the 35's I wanted to run.
as a note, the stock spring nut is a lock nut so I wouldn't worry too much about loctite.
