Video Transcript for Review of Convert-A-Ball Hitch Ball - Interchangeable Trailer Hitch Ball Set - 903B

Ellen: Hey everyone. I'm Ellen here at etrailer.com. Today we're taking a look at the Convert-a-ball Interchangeable 2-ball set. So we'll have two different sized balls to use with our two different sized couplers that we might be dealing with. One is going to be a one and seven eighths inch ball and the other one is going to be a two inch.Now the way that we're going to get these attached is just by putting them onto the shank here and then pushing this pin through. So it's just going to capture that shank and hold it securely.

Just place that over the top, line up the holes, and then push it on through, and that's all there is to it.That's something I really like about this system is that there's no tools required to get those balls changed out. Just a matter of pushing that pin in and getting that all the way out, switching it to the other one, and pushing that pin back through.So, really easy use. It does have a little O-ring there to keep out any kind of water or debris from getting into the ball whenever it's in use. Not a bad idea to maybe put a drop of machine oil or something like that on there to keep everything lubricated and working nice and smooth.Another thing I like about this is that they're made of stainless steel so they're not going to rust out anytime soon on you. It's going to be very durable, long lasting, and should give you years of good service.

The hardware is going to be made of a steel with a zinc coating to help resist any kind of rust or corrosion. Of course, if you want to make sure that everything is stainless steel, you can always switch those out for something more corrosion resistant, but that's zinc coating does a pretty good job of resisting rust itself.As far as the size, this going to have an inch shank, so any ball mount that has an inch diameter hole, this will work with that as long as it's less than two inches. Anywhere between an inch and two inches should work out just fine. We'll have about two and a half inches of total length for that shank. With the crush washer that comes with, you'll probably lose about a quarter of an inch, so that's where you get that two and a quarter inch of usable space.

Again, inch in diameter. The nut is going to be an inch and a half size.Now I'm going to bring in a ball platform so you can see what this is going to look like whenever you'd have it installed. Zoom out a little bit for you guys, as well. So just drop that through, put on our hardware, and then once we get this threaded all the way down, you want to make sure that you torque that down properly.The one downside, I would say, for that construction is that there's really no flat side to whenever you go to torque this. This is about the only flat part of it to grab onto to tighten that nut, so that's something that I would say is kind of a maybe a design flaw.

Just a design oversight. But other than that, and that's really only going to be something when you first mount it up, it's a pretty nice system. Customers have been using these for years. Convert-a-ball is a very well respected name in the towing industry, and people really have great results with these.I think it's a really nice system. Again, that stainless steel, you're never really going to have to worry about that at all. The towing capacity for this system is going to be 10,000 pounds of gross towing weight. That's for both size balls. You can also grab the two and five sixteenth inch ball. It works the exact same way, it's just that larger size. That's available separately here at etrailer.com, or you can buy a kit that has all three. So it's up to you there.It comes with a two year limited warranty from Convert-a-ball, and it is made in the USA.That's pretty much going to do it for our look at the Convert-a-ball Interchangeable 2-ball set.

I've used the convert-a-ball on another truck. Since I bought a new truck this is the only ball set up for me. I have a utility trailer with a 1 7/8" ball and farm trailer and wood splitter with a 2" ball. It's such a hassle to switch from one size ball to another plus damage caused by wrenches. With convert-a-ball it simply and fast. I won't ever go back to single ball system. 373906

Great product, but stainless washers and nut would have been a nice addition. 577555

Jury is still out on this, have not had a chance to install it on my truck, but did notice that there is some rattle to the ball once its installed on the hitch. Not sure if this rattle will effect anything while pulling or not.. will report back. Other than that, fit and finish is good and should hold up well to the elements. No more rusty balls! 546080

This is an excellent product. I had one previously and bought another from another company which held the ball on with a screw in the top when I couldn’t find another Convert-a-ball in local stores. Of course the screw rusted and the head stripped trying to change balls. I had to go online and found etrailer who shipped me several more Convert-a-Balls promptly. 609243

Great product. Very well built. I do wish that the nut, washer and pin were stainless. 592942

This is the second stainless steel "Convert-A-Ball" set that I have owned. The first was sold with my old car a few weeks ago. It is VERY easy to switch between a 1 7/8" and a 2" ball which I need to do several times a year. Previously, it was nearly impossible to switch the balls as you had to use a large wrench and a hammer to unscrew/remove the old rusted ball shank from the hitch. A fantastic invention and I recommend it to anyone. 591497

I found etrailer to have a great selection and service. I really appreciated the product use videos which helped insure I selected the proper size hitch for my vehicle. I received the product quickly in just a few days. I use two trailers requiring a different size hitch ball of 1-7/8 and 2 inches. I am looking forward to being able to switch the set-up with the Convert-A-Ball in just a few seconds without having to use wrenches. 366301

Saves time if you need both sizes, and you don't have to carry a large wrench with you. I would have rated it five stars if the burr/nut was stainless. 301744
