That would be the correct model to use, as for lifting 2 inches as claimed, i don't think you will see quiet that. It will remove any sag, and give you a little more lift. You could always add a lift shackle too, such as the warrior 153. I assume your looking to do the Torsion twist in the front and want 2 inches to match? The AAL might work for that, but if its sagging a lot to begin with you may want to add the shackles to level it out to the front a little better.
