I misunderstood your question. I thought you were referring to rear. My guess would be that the front is gained via the bumpstop replacement in combination with the high-angle ball joints and control arm. I haven't really reviewed the differences between the Stage 2 and 3 kits since I have to have the leaf pack because of my rear locker. That pretty much sewed up my choice. You might want to call Spence and ask him. He will talk to you if you ask questions.
