A time saver changing ball size ! BUT, my first one only lasted 2 or 3 years. The pins gave trouble, wouldn't go back in.


great service and fast delivery the convert a ball makes it easy when changing from one trailer to anther that’s calls for different size trailer hitches


Just what you need when you have trailers with different coupler sizes


Good solid product


This set works well. It is easy to change sizes and it has held up well. I had another cheaper one from a local store but that failed after just a few years. I expect this one to hold up much longer.


I have had one of these hitches for a few years and can't say enough about how great they are. So easy to convert from 1 7/8 to 2" without tools. I have had so many people ask me where I got it and I didn't know because I had it given to me. Now I can tell them it came from

Melvin C.


I love this Convert-A-Ball. It makes my job so easy.


I love Convert-A-Ball hitch balls. I have 6 vehicles and as many ball mounts depending on the vehicle/trailer combination. The ball mounts each have a stem and I can swap from 1-7/8" ball to 2" to 2-5/16" without tools! Makes life on the farm just a little bit easier.

Matthew R.


As long as the balls are stored in a dry place and the o-rings on the pins stay lubricated with grease or Vaseline, they work perfectly!


Trailer ball is of excellent quality. I am curious to see how well the sliding pin holds up to the salty road conditions we have here in Michigan. The pictured ball does show a safety cotter pin but it was not included

Marvin T.


Product still works great. Still very happy with it.


I had one before and now I needed another as I have two trailers with different hitches. Delivered quickly.



Just converted yesterday again. Cant do without it.


The convert-a-ball basically works well as I have equipment with both 1 7/8 and 2" receivers. I had a problem with my 2" ball in that the pin retainer inside the ball broke jamming the pin. I was able to drive the pin out and removed the broken clip wire. It is still usable although there is no retainer clip and I have to be careful not to lose the pin. This is probably an unusual event and I still recommend the convert-a-ball.


I ordered the Convert-A-Ball Interchangeabe Ball Set, after looking at other Mfgs. this set will allow me to use both the 1-7/8 and 2" hitches, which is most common, and I do own both size trailers. I like the nickel plating and the intergrate pin . I have had the Mfg. with the screw type top of ball, that became rusty and the spring and ball bearing fell out, safety wasn't good.

The order came within a week and was in great condition.

I will order again from etrailer again without a doubt.



Arrived as promised have not had a chance to put these to work. Material seems to be good quality and am hoping the Nickel finish will keep them in good condition!


I have had one of these types of receiver balls on my 98 S-10 for years and it never failed me ! My friends had those other types with the spring-loaded pin and the "zig-zag" channel and they always jammed up and mine NEVER did ! When I sold the truck I let the unit go with it ( I forgot to take it off), so when I bought another truck a few months later I got one of these again for my bumper. It is a no brainer.....


The order came within the wk I order it. This is the 2nd set that I have purchased, this set is for my son, as he just got a new truck and needed a hitch ball set that had both a 1 7/8" and a 2" ball. I purchased a Convert-A-Ball set like this one over a year ago and have not had a problem at all, and the convenience of changing ball sizes, and the safety that you have that the ball is held tight in the hitch, can not be matched.
What a great product!


I really like the products you folks sell. It's easy to see what's available and it's high quality. Thanks for the great service. The videos are fantastic!



Ive had zero issues with this product. The plating is holding up well. Its a cinch to quickly change.


Good Buy Product seems to be fine


My trailer and boat use different size hitch ball. It was very inconvenient. convert a ball is great. Very easy to change ball sizes in seconds. Great product.


Works great. I am very pleased. Delivery time was astounding. Arrived the next day. Love the cushioned ball mount - the 12 inch drop was perfect for my GMC Yukon where the receiver comes out of the bumper.


works good. Was a little sketchy on the whole interchangeable ball gig but it works great. I can switch balls from my boat to my motorcycle trailer in under 5 minutes.


Replacement for my current hitch, only needed the balls, but had to buy the whole unit. Only needed the 802, however.


Fast easy delivery!


convert a ball 10" drop hitch and balls. MADE IN US of A !!!! great American product and delivery was timely.


This is my second purchase of a Convert-A-Ball set and I'm loving them so far. A lot easier and quicker than changing ball mounts and a lot cleaner looking than those 2 or 3-way ball mounts.


I have about 4 sets of these, one for each vehicle and draw bar. One for the bike carrier, which has a draw bar too.


Very nice product with snug fitting. Entire product has nickel finish except the nut?? Also, product has been revised as there is no cotter pin below the nut to act as an additional retainer.

  • Is Convert-A-Ball Interchangeable Ball Set Secure Enough to Leave on a Ball Mount and Not Lose Ball
    With the ball # 901B torqued to the ball mount and one of the balls in place it will not go anywhere. You can leave it on the ball mount without worrying about losing the ball portion. Take a look at the video I have linked to see how it works.

  • Orientation of the Pin on the Convert-A-Ball Interchangeable Ball Set 901B
    The torque figure is 180 ft lbs. Sorry for the confusion there. As far as the pin orientation. Convert a ball tested that and determined that having it perpendicular was better. Having it that direction prevents the pin from getting damaged from front to back movement. Having it that way prevents the ball from not being able to change sizes when needed.

  • Recommendation for Replacing Broken Pin on 2
    The only hitch balls that I am familiar with that use a pin would be an interchangeable ball sets like the Convert-A-Ball, # 901b. Replacement pins are not available so your hitch ball would need to be replaced. I have attached a link to all of the interchangeable ball sets which include a 2" ball. If you would like to go with a standard 2" hitch ball, I have attached a link to those as well.

  • What is the Likely Ball Diameter Required for a 2012 Flagstaff Micro Lite Trailer
    A 1-7/8 inch ball is usually found on very small trailers. While it is possible that the trailer takes a 1-7/8 inch ball it seems more likely that it would take a 2 inch since the dry weight of the trailer is 3,630 pounds. The coupler should have the ball requirement stamped into the top of it. Most stand alone 1-7/8 inch balls max out at 2,000 pounds gross trailer weight though there are a few exceptions that are rated higher. Another option is to go with an interchangeable ball set...

  • Using Convert-A-Ball Cushioned Ball Mount with Surge Breaks
    The Convert-A-Ball cushioned ball mount # AMSC12 is absolutely compatible with the surge breaks on your tow dolly. You may not even notice it the cushion interacting with your surge couple. The way cushion is designed is that the more pressure that is put on it the firmer it gets. The cushion itself is so dense that more force would be needed to compress that cushion than to actuate the surge coupler. Where this ball mount truly shines is when there's a lot of road shock that needs to be...

  • Can a 2 Inch Trailer Hitch Ball Be Replaced with a 1-7/8 Inch Hitch Ball on a 2 Inch Hitch Receiver
    To replace the hitch ball you would simply loosen and remove the hitch ball nut and pull the ball out of the ball mount hole. You may need a large wrench to loosen the nut. The Tow Ready 1-7/8 Inch Hitch Ball, part # 19260, would be a great fit for your application, as it features a 1 inch diameter shank that should be compatible with your ball mount. Please note, however, that some ball mounts for 2 inch x 2 inch hitches require a hitch ball with a 1-1/4 inch shank. If your current...
