the ones that come from the factory on the rangers are valved differently than the regular bilstein hd's. they are all the same length, but from my knowledge, the factory fx4's with bilsteins came valved differently to ford's spec.
Those are the one i saw on ebay but i was left under the impression that the level II where i little bit longer then regular ranger. If they fit correctly i shure like the deal they have. Ill see by the end of the week what i buy. Mine are completely finish and im tired of the knocking sound they make on small bumps.
