Rockerball trailer hitch -- has anyone tried it?

Why?

So, it is a rubber mounted ball..

Looks like a "solution" looking for an application..

I get zero "lurch", I get zero clunks, zero noises..

If you are getting enough slop in your ball hitch to feel it move or make noises, it it time to throw out your hitch and buy a complete new hitch assembly!

The ball is not where the lurching is coming from, it is between the hitch receiver and the hitch shank being too loose of a fit..

When my newest truck came in with a 2 and 1/2" hitch receiver, I bought a new hitch shank only to discover the new hitch shanks are just as sloppy of a fit as using a 2" to 2 1/2" hitch adapter..

So..

I get out the 250A stick welder and some 1/8 rod and proceed to run a bead around the shank to reduce the slop..

Yep, slides in smooth with minimal slop..

Additionally, I suspect that having a rubber mounted ball just might make a WD system not perform as well as it should..

Do be aware, the ball in your link is a 2" ball, not many TTs use a 2" ball, none of the TTs I have owned use that size..

The only application I have for that size is my Log splitter and I used it only once to tow from the store to my home..

Most TTs you will find use 2 5/16" balls..
