Is it YOUR Dynamax sitting in a parking lot in Nashville?
We used to run a 2 5/16" ball, but if anyone wanted to tow their car, we kept a few 2" balls and then no one would bring them back. So on our new ones I had them install a "double ball"...I'll see if I can get a pic.
JUST an FYI for those people that would like to complain about the ball dragging...we did it as a courtesy, once you figure out which ball you will need you are welcome to get a single ball that would not interfere with your ground clearance
Or retain the one that gives you maximum flexibility.
