you might be right I do not know about that but what I do know from looking at them both just is that 1he 6'' comes with ad a leafs and the 4'' dose not every thing else looks the same to me but I could be wrong here are screen shots of parts6" lift is just a cranked 4" lift up front IIRC, so the 4" lift would yield better ball joint angles.
