Expert Reply:
Hey Roger, we went and took that measurement and found that it is 9-1/2 inches like you can see in attached picture. This would also have enough room for a Rock Tamers mud flap like the part # ERT00110 as well.

Hey Roger, how did the fit turn out with the Rock Tamers on that 9-1/2-inch ball mount? Knowing how much clearance you ended up with could help others setting up a similar towing setup.
