Draw-TiteTow Ready 63803 Interchangeable Hitch Ball

Finally, no more tools or multiple receivers to carry around when switching trailers.Edit: Been uaing these for a couple months now, and I'm still very happy. Something I didnt realize when I ordered: even if you somehow forget to push the locking pin down, just putting the trailer on the ball will hold the pin down and lock the ball in place. It made feel.much more comfortable with it once I figured that out.

It's very convenient because I don't have to carry around multiple hitches with three different sized balls on them!

I've tried other brand of interchangeable balls and this set is the best by far. After several months of hard dirty use, I can't see how this set would ever jam or freeze up. Swapping balls is easy. Highly recommended.

Absolutely the best ball aperture.

After a year or so the locking mechanism had frozed and was nearly impossible to get to release. When it did the ball bearings fell out. Putting it back together is not fun and ultimately the part is now unusable. not a good value.
