The shank and the head are two different parts of a WD hitch. Most WD hitches are installed with an adjustable shank. Unbolt the head from the shank, raise the head a notch or two on the shank, then bolt it back on. You may have to turn the shank over to get a rise instead of a drop.

And here is a link to an adjustable shank (or stinger as Cumminsfan called it). Adjustable shanks are available with various rise and drop measurements, so buy the one you need. This one is has up to 2" drop or turn it over and it has up to 6.5" rise:
