I started installing my new 2.5 inch ome suspension kit today and ran into a small dilema. I got a little excited putting my shackles together and didn't pay attention that the front were different from the back, one is longer than the other and I don't know which one is the which. Should have looked at the marked boxes a little closer huh! Can some one please tell me if the short shackle goes in the front or the back? I don't know if it makes any difference but the front are the heavy springs.
