Ok, have a question. I don't have part #'s but it's pretty simple....... I have Rancho 9000's all the way around. They are for a 2-4 in lift. A friend gave me some rear 9000's for a 4-6" lift. I want to remove the old fronts and move the rear shocks to the front and put the bigger 9000 rear shocks on the back. I'm thinking this will give me more travel. Will the old rear 9000's work on the front? Or am I wasting time?
