makes it easy to switch to different tr ailers.


Your products and service saved my bacon! The products preform better than the new truck I put them on and I will continue to use them as I replace my 2022 RAM with a truck I can depend on. An aside, DEF sucks!


Convert-A-Ball used to be top of the line, now they are stuck in the past.The big three have trucks that can conventional tow 20,000 lbs. or more, so the 10,000 lbs. rated Convert-A-Ball is just weak. I called them and asked if they would upgrade their product to match the new vehicles and they said no.I guess they are content to not change with the times and continue to beat a dead horse. I will not be buying their products in the future as I need a higher tow rating. Might copy their design and have my buddy with a machine shop make a good one.


ive had mine a year now and I can't believe I haven't tried this in years past, these are awesome, no more carrying the 3 other heavy receivers around.



love it,, no changing out the hitch with that knuckle busting pin.


I have several trailers utility, small boat and larger boat, that require different balls(that sounds funny but I'm amused). This product saves space and time in the truck only having to install the needed size ball onto the hitch. Converting from one size to another couldn't be easier, push the pin, pull the ball, put on the correct ball push the pin. Each ball has its own pin so there's never searching for a lost pin. It is taking you longer to read this review than it will to change ball size.


Super versatile and well made.


As a professional walleye angler I have been towing boats for over 30 years and this is one of my go to products having multiple trailer sizes. My tournament boat rolls in at about 6000 lbs give or take a few. also have to thank etrailer for the best customer service, with everything. Thanks everyone.


Works flawlessly and is a must have for multiple trailers.

Thomas T.


Wonderful, the big bonus here is the 10,000 GTW. Ive made all my couplers 2 so havent had to swap balls lately but always have them on hand if needed.


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.

Mike D.


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.


I have used convert-a-ball on my pickup for over 25 years


I tow many different trailers and use an adjustable height hitch bar. This product will make it much more convenient.

Arizona S.


Interchangeable balls have held up well, still easy to extract pins. A little grease on the pins helps.


Trailer ball was just what I ordered, it was delivered on time and works perfectly. We use several different trailers with different ball sizes, so this is very easy and convenient to change. Balls are also easy to store in your tool box so they are not lost. A high quality product. I will purchase from this vendor again.
Thank You,



all is well


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.


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.


I had a pin type trailer ball combination like this years ago. It gave me great services. But, when I sold that car, I forgot to take the trailer ball. Since then I have tried many types of trailer ball combinations. None were as good as the pin type. They repeatedly got stuck with road grime and required penetrating oil and hammer to get them free.
The only maintenance you will need on this pin type ball is a little light grease on the pin about once a year. When ordering pay attention to the mounting bolt width. My type II hitch needs a 1 inch bolt.
I am looking forward to years of service from this product. This is the only type of trailer ball combo I will buy.


Very easy to use and very convenient. I've several trailers and they all take different size ball. However after leaving the it on the truck for 3 months, I went to change the ball size. The pin came out very easily but the ball was rusted to the shaft,. I ended up taking a torch to the ball and two pipe wrenches to get it off. I should have spent the extra money and got stainless. The nickel finish is worthless.


Great Product. Fit is nice and tight so no rattling from the ball. The nickel finish looks good, but does wear off the ball pretty quickly. I've combined my Convert-A-Ball with an adjustable draw bar so I can pull any trailer in a pinch. Well worth the money if you need to pull different trailers.


I've been very happy with my purchase of my hitch and harness. Shipping was fast and I've towed all kinds of stuff since I made my purchase. I recommend these guys.


The convert a ball is great when having to change trailers with different size ball hitchs.


Very easy to use around the farm when we have trailers that need three diffrent balls.



Wow, I was told etrailer had good service. This exceeds my expectations. Yes the convert-a-ball works great on the farm beings we have different trailers with different sizes of ball hitches. Great customer service Patrick. Thanks for everything.


So far so good.. I can still unlock easily after driving up and down dirt every day.


I already have and use these products. They are the best I have ever had on my truck. Towing is perfect with no wobble sway or play. The unit I purchased is a birthday present. I will follow up with his comments



Better than anticipated


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.


It's a great way to avoid carrying 3 ball mounts and still tow up to 10,000 #.

John U.


Still works great. This is not my first one, so I expected that..


Got 2 sets. One for my truck and one for

My brothers truck..Have owned convert a ball

Hitch on previous trucks...couldn't find any

Locally. ..e trailer to the rescue...Thanks..

  • Availability of Interchangeable Hitch Ball Set without Built in Scale
    We have the Convert-A-Ball Interchangeable Ball Set # 900B that has all three common hitch ball sizes of 1-7/8, 2 and 2-5/16 inch that can be swapped out and does not have a scale. I attached a review video for more info on this as well.

  • 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 the...

  • Would the Convert-A-Ball Interchangeable Ball Set 900b Fit a 1 inch Thick Ball Mount Platform
    As long as the ball mount platform of your ball mound has a hole diameter of 1 inch the part # 900b would fit and work well. The length of the shank on this ball is 2-1/2 inches long so it would work well with a platform that is 1 inch thick.

    I spoke with someone at Jayco who said that most of the 2019 Jay Flight SLX 8 264BH travel trailers have a coupler that matches a 2-5/16" hitch ball but since there can be some variances she couldn't guarantee that's what your travel trailer has. If you already own the travel trailer then the coupler size should be stamped on the coupler itself. Otherwise the only other way to pinpoint the size hitch ball you need is to contact the seller.

    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.
