Video Transcript for Convert-A-Ball Balls 902B Review

Today were going to review part number 902B. This is the Convert-A-Ball interchangeable ball set; contains three different hitch ball sizes and a shank. The shank is a solid stainless steel one-inch diameter shank; comes with a three different size hitch ball the 2 5/16, the two-inch and the 1 7/8 and they all are stamped on the top with the size of the hitch ball. This is a nice item to have if youre towing different size trailer couplers. Youd be able to change out your hitch ball size for another ball size very easy. You just pop out the integrated pin that is on the hitch ball and then replace with any size hitch ball unto the shank.

Includes the one shank, the three hitch balls and well include the 1 inch nut that uses the 1 inch wrench to attach the shank to the ball mount and the washers included. I would go on there and you need to tighten it down to the ball mount. It also comes with a cotter key that will slide through the hole and we keep the nut on the shank. This does stand up to the weather and moisture with the quality and durability of pure stainless steel. This part is made in the USA and, again, I want to show you this shank will fit ball mounts with a one inch diameter hole.

Theres the diameter, its one inch; give you the shank length which will be 2 inches.The towing capacity on these shank and the hitch balls is 10,000 pound gross towing weight capacity. This part does come with a two-year limited warranty and just to give you an idea of how this would attach to the shank with the shank mounted unto your ball mount. You will find the side of the pin that has the dimple in it and you could just actually could push it out with your finger and do it that way sometimes with your finger or it might not push out enough, you can use a pin to do it but this integrated pin will stay in there. And the nice thing on these pins because if youll notice theres a rubber O ring on each end of the pin; on this end and on this end. So when this is installed and pushed in, it will actually seal both sides of the hole so no dirt or foreign material wil get in to here and cause any problems.

So basically you push the end with the dimple in it, take your shank where the hole is, line it up with the pin, just push through all the way until its flush and boom, you have a hitch ball of 2 5/16 in size. Now if you need to switch it out, just take the two-inch, find the side with the dimple, push it, pull it all the way, line it up again with the holes all the way until its flush and you have another size on there. And again, you can do it with the smaller, push it open line it up, all the way and in a few seconds youll change out all three different hitch ball sizes. Again, this part comes with a two-year limited warranty and that should do it for part number 902B. .

Have a set of these convert a ball and love the fact I don't have to have two or three different hitches or ball mounts for each ball. Or a ball mount that you have to rotate to get the ball size you need. 225951


I love the product. I already had or own an ball mount and theconvert a ball setup. That is the reason I purchase another one but with the four inch . I have and will to continue to recommend the product.

The kind of balls you need... A little pricey maybe... But then again they are stainless. I feel it's worth it. Buy them! Buy the case to put 'em in and store it behind the seat of your truck. If there is ever a chance that you will use them it is cheaper this way than any other. I have towed trailers that require all 3 of these sizes, and use 2 sizes on a regular basis. Just came back from a 200 mile bumpy dirt road trip with 3,000lbs and my 2" ball is still shiny new. I also highly recommend the "cushioned" ball mount to go with it. I have used the $250 aluminum rapid hitch setup and now I won't use it again. This setup is the way to go. No sloppy jerky movements and aluminum that chips and dents and needs to be polished. Great Product, Great Price, Great Experience, Great etrailer!!! 5371

Exactly what I wanted. Stainless is the way to go. I will say I have had this type ball before. (steel) the rubber o ring on the cross pin appears to be the only thing holding the pin in when not being used to tow a trailer. After 7 years the o ring rotted out and the ball bounced off. Lesson: when not in use keep it out of the elements and this thing will last forever!! Awesome product! E trailer has the best customer service around. Ordered online and had this in hand in 4 days! And that was choosing the cheapest shipping option possible! Thank you E Trailer!! David 132244

I have these on my vehicles, and bought this one as a Christmas gift. It's the only way to go. It takes seconds to change balls, and they work flawlessly- as long as you take the ball off the stud each time you use it. My first set, chrome plated, froze in place after a month in a Minnesota winter. I had to throw it away. If you can afford it, get the stainless steel. But even it will freeze up if you don't remove the ball after using it. Removing the ball or the receiver is a small price to pay for versatility of the system. 28669

Always prepared The 3-ball convert-a-ball system and cushioned ballmount was the first first and so far only ballmount and ball set I've purchased. I normally only use the 2-5/16" ball but it's nice to know the others are there when I need them. I went to go pick up a trailer from a friend once. He told me it had a 2" hitch but it was really 1-7/8". I had brought the complete kit just in case. He was amazed at how fast and easy it was to change ball sizes. With the 10k rating it will easily handle anything I'll ever tow. 1576

The product is of the highest quality and the delivery timetable is as fast as could ever be expected. Not only did I get a great product but pricing was so good I will never buy from anywhere else. And it was so easy, not needing to go looking at one store then another. I ordered from my home not taking very much time at all. If I had to do this over again, I would do exactly as I did this time. is the way to go. 257100

I was looking for the Convert-A-Ball trailer hitch that was made in America. This web site came up and I liked what I saw. It was easy to use. I ordered on Tuesday the week of Christmas thinking I wouldn't get it until after Christmas. However, I recieved the package 2 days later! WOW! My husband and I were very impressed. Good quality, fast service and good customer service. We will recommend this company to our friends! 28883

Excellent product. My previous convert-a ball system was chrome plated but I much prefer the stainless . The chrome plating wears off after a few moths of use and you are left with a rusty hitch ball . The convert-a ball system is the ONLY way to go if you have multiple trailers with different hitch ball sizes. Great price and extraordinarily quick shipping from the good folks at etrailer. 128015

The Ball Mount and Convert-A-Ball are of top notch quality. I applied both on my receiver and they fit perfectly. The lock for the mount is state of the art. Furthermore I received emails when the item was picked, shipped and given a due date and I received it right on time.This company is on top of there game and I will be doing business with them in the future. 36445

This is great I love the concept of not having to change out a different ball or have three hitches laying around every time I pull something different, ( i have three different trailers ) I'm also happy I went with the stainless steel it looks great and should remain that way for years to come! Thank you! 221798

These are very nicely made and well machined. I like the versatility this set provides for towing multiple trailers. I have a travel trailer that uses the 2 5/16 ball and a utility trailer that uses a 2" ball. I no longer need multiple ball mounts. Just swap the ball & go. 85721

by: Robert04/17/2012

The order arrived complete as expected. The hitch looks of high guality and hopefully will resist rust as it should being stainless steel. Only time will tell for sure. The storage box is a "very nice to have" item to keep the loose ball sizes stored out of the way. 37530

by: JR T07/28/2011

USA MADE PRODUCT! Quality throughout. I kinda wish the nut, split washer and cotter pin were also stainless. (They're not... they're all zinc coated.) I like the idea of the o-rings on the locking pins. Keeps the crap out. I'm happy. 48783

  • Availability of 10K Ball Mount and Multiple Hitch Balls for Class III Hitch on 2015 Toyota Tundra
  • We do offer a range of cushioned 10K-rated ball mounts for a 2-inch hitch that can be seen by clicking on the included link. These are available with a range of rise or drop to suit your trailer's coupler height, which you'll naturally want to be level when hitched. Do note that while the ball mount is rated to 10K the size of hitch ball you use will also determine towing capacity. For example, the ball mount # AMSC2 that you referenced has a 3/4-inch rise or a 2-inch drop. If used with...

  • The Alumistinger Ball Mount, # AM3503, will accept a hitch ball with a 1 inch diameter shank that is at least 2 inches long. I added a link to all of the hitch balls we carry with a 1 inch diameter shank for you to review. You will also need to select a ball that is the correct size for your trailer coupler. I would recommend going with the Convert-A-Ball 10,000 lb Interchangeable Ball Set, # 902B, which is stainless steel for longevity and includes all three ball sizes.

The advantages of a 2 inch, Class III hitch are, as you have pointed out, greater weight capacity, more options for accessories, and you will be able to use weight distribution if you wanted. I have included a link to the installation details and a video installation below. You will also want to check your owners manual for your vehicle towing capacities. The...

We also have convert-a-ball hitch balls that go up to 10,000 lbs. If you are using the convert-a-ball system, the pin will lock into place and not fall off, even if no trailer is hitched up.

  • Can the Convert-a-Ball System be Left on the Draw Bar when not Towing

And third, a hitch cover will keep water off the ball, which is not as big of deal with stainless, but it is a good practice. I have added a link to...
