If I understand the question correctly.... I would say no. The ball mount is rated according to its function,which is being bolted down tight. A D-ring ( and this is where I got lost) is bolted but pivots and moves causing stress friction that ball mount might not handle.

Better safe that sorry, right?

Who uses a d-ring ? ....The farmer who pulls me out of his corn field with a tractor
