2012 Ford Dually

Im looking for any information or the owner of this Ford Dually. I saw the picture on 323 Duallysportz. My duddy has the same truck and we are trying to figure out what is all done to make it this low since the didnt make a 2wd. obviously its air bagged but how is it setup and what not

Its a 2wd and I'm the one who took the pic those guys just used it.....its a 05 with 2012 front end swap
