The shaft portion of the Demco 5th Wheel Base Rails Adapter # DM6140 that you referenced is vertically adjustable so that you can match the height of the bed perfectly. This is helpful when the truck has a bed liner and the bed floor is slightly raised because of it.

I attached a picture that shows how the adjustment is made.
