Not sure. It was purchased this way. It does work well at 35 and under. Just spins way to fast for my actual speed, found a tutorial over on the H.A.M.B. for lubing the head. Not sure this is going to help me though as it spins too much. I would not be able to tell if it is an original or correct setup as I have no prior experience as to what this hook up should look like. Again it works like it should up to 35 mph.
