yea, torsion twist and lots of people have been putting on Warrior Shackels and AAL's too, i think the max you can go on the TT is 2" because you have 4wd (something about the angle of your cv joints i believe) and im not entirely sure how much lift the AALs and shackels add yet, i think its around 2.5" of lift, but it varies from exlporer to explorer
They have a write up on excatly how to do it, if i had more time, and wasnt lazy i would find it and link it for you. Its under the useful links or something. It looks as if any regular person could do the AAL and shackels, and if you know how to use a ratchet it looks like you can do the TT as well...hope that helped.
anyone feel free to correct me if im wrong on any of this...just what i picked up from reading around...
