Product functioned as expected. Stainless steel ball is great. Thanks



by:

1 year review: terrific product that I wish I had invested in before. No more swapping the receiver hitch, just the ball. It’s so convenient.

Great quality here, should last forever.

Good product, I’ve sold my large and small trailers, only use 2” ball on what I have left. No need for this multiple ball setup anymore.



by:

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.

Great!!



by:

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.



by:

Love this product! I've had a Convert-A Ball set on my truck(s) for about 15 years. I use the 1 7/8" and 2" balls several times a month. It takes about 10 seconds to switch between the two. Much easier and cleaner than switching out ball mounts. These are replacements for my original balls. The locking ring on both balls finally broke and while I continued to use the balls without them, eventually the pins fell out on the road. I figure 15 years of serviceable life is a bargain. I'll use the extra new shank on a ball mount with a different drop so it won't go to waste. Buy these. You won't be disappointed. Also bought a trailer hitch from etrailer for my son's Hyundai Santa Fe a few months ago. Great service and followup from etrailer on both orders. Thanks etrailer.



by:

ellent product. I have had several over the years. Spend the extra money to get the stainless version. My first was not and rusted together so that I couldn't change the balls. I just purchased two more. One to replace one that was stolen from my Yukon XL in a parking lot, and one for the drawbar on my tractor. I have a flatbed trailer to carry the tractor, a small dump trailer, and a log splitter so I am continually switching among all three size balls. Very convenient.



by:

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.



by:

Package was received with one corner of cardboard box crushed a bit but still intact. Missing from the box were the 5/8 pin and clip. Called customer service and discovered the issue was there were none in stock so those parts will be shipped when received at etrailer. Lady that answered the phone was very helpful and knowledgeable. As for the hitch and ball, I’m sure it will perform as well as the one I had before I was rear ended in an accident. The whole experience with all at etrailer was seamless.



by:

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.



by:

Convert-A-Ball is still my favorite style of interchangeable ball head size systems. I strongly recommend the Stainless version as the pin in the regular chrome versions seem to rust and hang up on you after a couple of years. It is also great to be able to purchase just the two ball version in stainless which includes the 2" and the 1 7/8". I have no need for the 2 5/16" ball, since most of my towing is only medium to light duty.



by:

I use this ball for one year. Super good product, no rust, no issue. Extra good quality. Practical and it's easy to store the axtra ball in the spare compartment. Highly recommand this product, and these sellers!

THIS IS A MUST! After a year, Non issues, work perfectly!, Good product.



by:

A great convenient hitch. Easy to swap out the hitch balls without wrenches or multiple hitches.



by:

I received everything I ordered in just 3 days. The packaging was good with no damage on any of the parts. Everything fit and I'm ready to tow the boat. Looks like a fishing weekend with the grandkids. Thanks for the fast service.

After many miles of towing I am still happy with the quality and convenience of the convert a ball



by:

The stainless Convert-A-Ball and a chrome receiver make a good combo and stay looking nice. The ball doesn't show any wear. Easy to change ball sizes.



by:

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!



by:

best product i've ever purchased. I am constantly changing from 1 7/8 to a 2 inch ball. slickest product out. I would suggest purchasing the stainless steel and avoid and corrision. pete from minnesota



by:

This is an outstanding product! I am sure it will not rust and will yield many
years of service towing my golf cart and motorcycle. etrailer is a great company to do business with as their shipping is very fast and their communication is excellent! I highly recommend them!



by:

It just works simply and wellI have used this product on two of my cars for over two years. I often tow Junior Sailing trailers and the ball sizes vary. This makes switching ball sizes really easy. Wonderful product. I have recommended them to many and those that purchased the interchangable balls have also been really pleased.



by:

This is a well made and nicely finished trailer ball. The mechanism for changing the ball works well and appears to be quite robust and safe. It is convenient to be able to change the ball quickly without tools. Since it is machined from stainless steel it shows no wear or discoloration whatsoever.



by:

The ball and shank are holding up well after 1 year and I swap the balls frequently. The hex nut is zinc coated steel (not stainless) and is now quite rusted - this product would be better completely stainless.



by:

Stainless Steel Ball setGreat and strong product, rated stronger than Hitch so this is the one item that shoudn't fail you under heavy loads. I have this installed on a 2" Stainless Steel Ball Mount and in use on my 2007 Tacoma D-cab.



by:

Very nice, except the nut, lockwasher and cotter pin are NOT stainless steel.



by:

I found this Ball Set convenient wlth uses of different hitch size, and that without rust.



by:

It is disappointing that a stainless steel product includes a non-stainless nut, lock washer and cotter pin.

  • Nut and Washer Material on the Convert-A-Ball Interchangeable Ball Set # 903B
    The nut and washer included with the Convert-A-Ball Interchangeable Ball Set, part # 903b are zinc plated steel. They are not stainless steel, like the rest of the assembly. I have included a link to a video about this interchangeable ball set for your reference.

  • What U.S.A.-Made 2" Hitch Ball do You Recommend?
    I have a great solution for you. However, the 2" Hitch Ball - 1" Diameter x 2-1/4" Long Shank - Chrome - 12,000 lbs # 40038 is manufactured overseas. For a great U.S.A.-made option, the closest 2" ball we have to the 12,000 pound capacity of the Curt model is the Convert-A-Ball Interchangeable Ball Set - 1-7/8" and 2" Balls - 1" Shank - Stainless # 903b. This ball comes with a 10,000 pound capacity and comes with the same 1 inch diameter x 2-1/4 inch long shank.

  • 2" Diameter 10k, Stainless Steel Hitch Ball Recommendation for Solid Aluminum Ball Mount # DTBM4400
    The only stainless, 10k rated, 2 inch hitch ball option we offer that's going to fit the Solid Aluminum Ball Mount # DTBM4400 that you referenced is the Convert-A-Ball part # 903B. This comes with the quick-change feature to allow you to go from a 2 inch to a 1-7/8 inch ball. Or if you would prefer 2 and 2-5/16 inch balls you would want the # 906B.

  • Where is Brophy 2 Inch Stainless Steel Hitch Ball Made
    Brophy hitch ball # SC23-C is made overseas. For a stainless steel option that is made in the US you would have to go to an interchangeable set, # 903B. I have linked a video review of this set for you.

  • Can Lower Part of the MaxxTow Ball Mount # MT70068 be Purchased for Different Hitch Ball Size
    The MaxxTow Adjustable-Height Ball Mount # MT70068 is sold as a whole unit so the base part isn't available separately so you would need to purchase 2 of these if you are needing to use 2 different size hitch balls, or you could use an interchanging hitch ball like part # 903B. We actually have another solution with the Rapid Hitch Adjustable Aluminum Ball Mount Kit - 2 Zinc Balls - 5-1/2" Drop, 6-1/2" Rise Item # AM3411 comes with 1-7/8" and 2" hitch balls. Simply flip the ball assembly...

  • Availability of 1-7/8 Inch Trailer Ball w/ 1 Inch Diameter Shank
    The shank diameter of the trailer ball needs to match the hole diameter of your ball mount, which can be accomplished a few different ways. You could use a ball with a 3/4 inch shank like # 19256 as long as you used a reducer bushing like part # C21100. Another option would be to use a 1-7/8 inch ball with a 1 inch diameter shank like part # 19260. What might be the best option would be to use an interchangeable ball system like the Convert-A-Ball # 903B. This system includes a 1 inch...

  • Recommendation for Easy Ball Change on the Convert-A-Ball Dual-Cushioned, Adjustable Ball Mount
    There is not a replacement ball mount available for the Convert-A-Ball Adjustable Cushioned Ball Mount, CAB-UM, but there is what I believe is a better solution to your dilemma. The Convert-A-Ball Interchangeable Ball Set, item # 906B, would give you the ability to change out balls just as quickly as changing out the adjustable ball mount and would be much easier to store in the vehicle. This kit has 2-5/16 inch and 2 inch balls. If you need 1-7/8 inch and 2 inch balls the Convert-A-Ball...

  • Help Finding a 2" Hitch Ball For The Bumper Of a 1999 Toyota Tacoma
    I searched your owners manual and could not find any reference to ensure your rear bumper on your 1999 Toyota Tacoma is rated for towing. Because of this I recommend installing a etrailer Trailer Hitch Receiver # e64AR. This will ensure you do not damage your rear bumper or frame. I recommend using the Ball Mount Kit # EBMK4 with this receiver. It allows you to quickly switch from either the 2" ball you need or a 1-7/8" ball sometimes found on smaller trailers you may tow. I do know there...

  • Adjustable Ball Mount to Allow Motor Home to Pull Vehicle on a Tow Dolly
    It sounds like by "hitch" you mean a ball mount with 10-inches of height drop. The part you referenced, Roadmaster High-Low Hitch Adapter # RM-048-10, does provide this amount of drop but is intended only for applications that use tow bars to flat tow a vehicle. It is not suitable for use with a hitch-mount tow dolly like the Roadmaster # RM-2050-1, if that is what you have. We do offer a fixed ball mount from Convert-A-Ball Ball, their # AMSC10, that provides 10-inches of drop (or 8-3/4-inches...
