Video Transcript for Convert-A-Ball Balls 900B Review

Today were to review part number 900B. This is the Convert-A-Ball Interchangeable Ball Set. This ball set will come with a chrome, one-inch diameter long shank, comes with a three hitch balls, a 1 7/8-inch which is usually marked right on the top, the two-inch which should be marked there and the largest 2 5/16. This does have a 10,000 pound gross towing rate capacity. It is corrosion and rust-resistant and what this does is it makes changing out your Convert-A-Ball hitch balls with another ball size very easy; you just pop out the pin like that pin there and you replace it with any ball size that youre going to be towing. It includes the shank and the three heavy-duty balls.

Now, this part does use a new non-electric nickel-plating technology that produces a strong protective finish. It is corrosion-resistant, non-magnetic and stain-repellant and when its done it does have uniform coverage which will cover even hard to hit to recesses and it is an eco-friendly plating method which is less harmful to the environment than the traditional chrome electro-plating. This part is made in the USA; now it also comes with the washer and a nut which uses a 1 -inch wrench size to install the shank to your ball mount; you put the washer on and then put the nut on and tighten it down. It also comes with a cotter key that would insert after the bolt shank is installed; put the cotter key in that will help keep the nut from coming loose.Now, the shank does fit the one-inch diameter ball hole. The shank length is 2 and again it does have all three of the ball sizes.

This part does come with a two-year limited warranty and basically what I want to show you is how the balls will install onto the shank. What you do is to have a pin that is inserted in them, youd find the side that has the dimple on the pin and you could actually push it with your finger but sometimes your finger wont push it out enough to be able to grip it so what you want to do maybe is you just get a pin or screwdriver or something. Push it out, pull it all the way out. The other neat feature on the pins is if you look on each end of the pin there like a rubber O ring on this end and on this end and whats nice is when this is installed and completely inserted, it will seal to keep any dirt or anything from getting in there and causing any corrosion or problems. So, again if you pull this all the way out and then you have the hole in your shank, you just line it up with that hole push it through all the way so its flush and that will give you your 1 7/8inch size hitch ball then if you need to go to a different size, in this case the two-inch, again, just push the pin out all the way and line it up with the hole, all the way in, youre fine to go.

Take if off with your hand and where you can do the last one. This is the larger 2 5/16; just line that up, push it in. So, right there in a few seconds youve covered all three of the hitch ball sizes. This part is made in the USA and that should do it for part number 900B. .

Very ingenious idea. Saves the hassle of having to switch receivers every time I change the type of trailer I'm towing. Also bought the carry case and hitch cover - very pleased with the purchase and would recommend to a friend! Thanks to etrailer for shipping the items so quickly and their usual outstanding service. 115586


Absolutely love this product. I have two utility trailers with different hitch sizes and this has been so much more convenient than having to switch receivers. The case and hitch cover are a MUST to complete the set. Very, Very pleased and, as always, you folks have excellent service and support.

very nice convert a ball This was to replace an old convert a ball that I had with a lower tow rating. I love how the new convert a ball holds the pin for the ball in place when not in use. The old ones would always fall out and I would have to figure out which one went with which ball each time I used it. I also like how the new one has a cotter pin so the nut can’t back off. I never had an issue with the old one but this is a piece of mind that it can’t. So this is a great improvement over the older versions. 2686

The interchangeable ball set is great! They're all extremely solid and should be able to handle anything and everything I throw at them. I wouldn't advise letting any of the balls stay on the pin when you're not towing - even though the pins are tight to begin with, I've seen some come loose over time, and without a trailer to keep the ball down on the pin, I'm sure they could vibrate off. 65492

I love the nickel plated finish. I bought this product in conjunction with an Alumistinger ball mount. I believe the extra cost of having this interchangeable ball is more than offset by its versatility of having different size balls that can be quickly changed as well as having a finish that is very resistant to rust and corrosion. Very heavy duty as well. 48112

Product as described, as pictured, and all the specs were correct. I needed an adjustable hitch for different trailers (height) with a drop/rise of 8" and had a 2" ball and needed a 1 7/8's, so I decided to install this to have a hitch that can adjust to any height within a 16" range, and always have the right size ball. Would buy again. 101389

by: Tom05/06/2015

These are great. I have a set in the truck and SUV for general trailer pulling. With one shank and an adjustable hitch, I can adjust for any height or drop (+/- 10") and any size ball for under 100 bucks!!!!. Can't be beat. I do prefer the solid shank balls for anything really heavy (over 10,000) as I do trust them a bit more. 190981

Love the flexibility this offers. Since I haul mostly rental trailers, I never know what size ball I'll have. This makes it quick and easy to change to whatever I need. I'd suggest a bag to carry them though, I keep them in the spare-tire well, and they roll around if they aren't contained in something. 79760

Do you have a question about this Ball?

  • How to Remove a Stuck Convert-A-Ball Interchangeable Hitch Ball
  • I spoke with my contact at Convert-A-Ball and was told that you should try to use a brass punch initially. If the Pin in the Interchangeable Ball Set, # 900B, will not move with the brass punch you will need to attempt to use a harder steel punch. Some penetrating lubricant, like WD-40 or PB Blaster may help with removal also. If a steel punch will not dislodge the pin, you will need to have the pin pressed out, a local automotive shop should have a press that can perform this operation. If...

  • Does a 2 inch Trailer Ball fit the MaxxTow Adjustable Ball Mount # MT70067
  • The thickness of the tongue on the MaxxTow Adjustable Height Ball Mount # MT70067 is 3/4 of an inch, and it works with trailer balls that have a 1 inch diameter shank. The interchangeable Convert-A-Ball Trailer Ball Set # 900b, that is recommended for use with this adjustable ball mount, has a ball with a shank 2-1/4 inches long and 1 diameter. So it is possible that a trailer ball with a 2 inch long shank may work for you depending on the thickness of the nut and lock washer used...

  • Shank Lengths of Convert-A-Ball Interchangeable Trailer Ball Sets
  • The Convert-A-Ball trailer ball sets are available with shanks that are 1-3/4 inches in length, like part # 802B, 2-1/4 inch shank like part # 900B or with a 3 inch shank length, like part # 105TB. The shank length refers to the length of the shank portion that passes through the ball mount. The longer shank lengths are provided to fit thicker ball mounts. Generally speaking, the balls with the longer and greater diameter shanks have a higher weight capacity.

  • Tips For Removing a Rusted Interchangeable Ball from the Convert-A-Ball Ball Set # 900b
  • If I were you I think the first thing I would try is soaking the assembly in gear oil overnight or longer. Letting the oil penetrate for an extended period of time really should loosen it up. A torch or soaking in vinegar are options as well. I think I would try the oil first, then the torch if it is still being stubborn. You might use a hammer or rubber mallet on the ball to apply some force to break it free. This can work on either set you have. You would want to put the shank or...

Then the locking pin is pushed in place thru the holes and locks. To remove the ball you would press the dimple on the end of the locking pin, which releases the pin and it can be pushed out. The hitch balls only attach to the included post and shank, they will not work on a different ball post. I...

  • You will want to make sure you have the correct hitch ball mounted for your 2001 Keystone Camper. even though a 1-7/8 inch ball will fit, it can become a major safety issue if the coupler is designed for a larger hitch ball. One big bump and the coupler could jump off the smaller ball. If you are unable to determine the ball size you have a couple of options. You will want to measure the hole on the ball mount that the hitch ball shank uses. I imagine it is 3/4 inch, but some ball mounts...

  • Ball Mount with 6 inch Drop and Interchangeable Ball Set Recommendation
  • The thickness of the sway control bracket part # RP26003 that you would need is 3/8 of an inch. The ball mount you are interested in part # AMSC6 calls for a shank that is 2-1/8 inches long. So the interchangeable ball set you would need would be the # 900b as it comes with a 2-1/2 inch long shank.

  • Adjustable Ball Mount for a 2009 Toyota RAV4
  • You can use an adjustable ball mount without a weight distribution system. There are many adjustable ball mounts that are meant to be used without weight distribution. Also, a weight distribution head can be used for normal towing if desired. I don't see a problem with using either adjustable ball mount, # 80414 or # 80412. The hitch relative to the back of the vehicle and spare tire would not be a problem. Ball mount # 80414 is slightly longer so if you are concerned I would go with...
