I am a custom fabricator but have not messed much with lifts. I spoke to the performance shop that did the lift on the white H2 in the NH White mountain happening and he said those shocks are about 500 a piece and just trying to lift the H2 with those alone will pose a potential risk on the half shafts. Now that I think about it that my be the reason there is not a good 2" lift available. He said the with the 4" lift they provide a spacer to keep the half shaft in it's proper location. Perhaps with a 2" there is not enough room to add a spacer yet far enough away to pose a problem??? I just got off the phone with the performance shop who seems to be very knowledgeable and he is going to get back to me shortly with any info on a 2" lift, or if there would be a way to achieve it.
