This is what I was wondering also. If the diff itself will move up four inches and down 4 inches, for instance, and the mounting point of the shock is halfway between the pivot point of the arm it is attached to and the diff, then the shock will only see half that movement, or two inches up and two inches down.

I guess the question is, what is the amount of movement you are thinking at the diff itself, how long is the arm from the diff to the pivot point and where is the shock mounting point on that arm, how far back from the pivot point.
