Good and Bad about Blue Ox Sway Pro

If I follow your video, when the TT is not in a straight line the added tension on one side will help pull it back into line. Wouldn’t all designs do that? Second, how far out of line does the TT need to get on a typical 1000# hitch setup which seems the most common. Would the TT need to get several degrees or feet off center for physics to kick in on the bars to pull things straight? I thought I read that you got rid of the torque bolts to prevent “dog tracking” but other friction systems don’t seem to have that issue unless they are way too tight or on something like a snowy road.

Thank you for your interest in the Swaypro, we built caster into the trunions of the hitch head. This is what gives you the sway prevention and the friction sway control is not needed, it does not need to go off center for it to work, it is always working. This is similar to caster in a car, when going down the road the caster built into your front end keeps you straight going down the road and returns you to center when turning a corner. Blue Ox Swaypro is unique in the built in caster. I hope this answers your questions below. Please let me know if you have further questions.

I consider this to be a very disappointing response to your specific questions.

You asked, "Wouldn't all designs do that?" The response was, "we built caster into the trunions of the hitch head."
The only thing different about their hitch is the trunnion angle is not adjustable.
Other hitches can be set at similar tilt angles.
Does that mean they also have built-in caster and don't need any other sway-control mechanism?

The only parallel I can see with automobile front-suspension caster is that the automotive kingpin pivots on a axis which is "tilted" rearward at the top,
and the WD bar trunnion pivots on an axis which also is tilted rearward at the top.
But, the similarity ends there.

To have a "caster" effect, a wheel needs to be attached to the lower end of a kingpin so that the wheel's contact point with the pavement is behind the point at which the kingpin's axis intersects the pavement.

And, whatever effect the Blue Ox tilted trunnion has, it is not unique.
