It looks like the ball that comes with the hitch is round at the top. Back to the first post with the link to their web site. Looks like you have to use that ball because it is part of the system. On their web site scroll down to the picture that shows it and click on the picture to enlarge it.
Hi Campin,
H'mm good point as I too now remember that image of a complete round sphere. Like this one?
However I think we have been computer model tricked again. Those parts are suspended in mid air and a good 3D CAD program can look pretty real now a days. That total round top ball may be the CAD tech just left off the flat top. If you look at the hex head bolts on the shank there are no bolt grade stamp markings. It is a solid model image not the real thing.
See these pic's, this is a pic and not a computer model. It is the actual manufactured part, not a sales promo. These are clips off their video. Look at the flat spot on top of the ball.
Now that I see that flat spot on their tow ball it makes me question why is it there? Even my 1/2 a dozen 2" draw bars with 2" balls have a flat spot on the top. A thought is that the flat spot is machined in on purpose to not have the trailer tongue weight press exactly down on the coupler and ball center. Since it is machined off the tongue weight is moved to the outer sphere to support the load.
There is some intentional reason the ball has a flat spot on top. It is an additional setup step to machine off that flat. Any one know the reason?
Hope this helps
