I run 31's with a shackle lift, I think I have 1.5" of lift. I didnt really accurately measure before i installed, but I can let you know tomorrow what the current measure is. I don't have any rubbing, and I think the end results are pretty good. I thin k I put it on before the tires, but really don't remember, its been a few years. The main point of improvement was the zerk fittings and new bushings. Before that, every bump sounded like I had dropped the Jeep off a cliff. Now it just sounds like falling off a building.
