Video Transcript for Convert-A-Ball Hitch Ball - Trailer Hitch Ball - 904B Review

Today we're going to take a look at the Convert-A-Ball Interchangeable Ball Set, part number 904B. This item here allows you to haul two different sized trailers using just the one hitch ball mount. It comes with everything you see here, the shank, two hitch balls, a 2-5/16 inch ball and a 2 inch ball and the nut and washer.It is corrosion resistant and nonmagnetic as well as stain repellant. It provides uniform coverage even on hard protect recesses and interior surfaces. It has an eco-friendly plating method that is less harmful to the environment than the traditional chrome electro-plating. The way this works whenever you want to use one of the balls, right now I have the 2-5/16 inch ball.

You see that bar right inside there, there's a divot on the one side and you just poke that in with your finger or pin that comes right out of there.As you can see here on the shank there's a hole, pop that in, then you match your hole up, pop that through and its on there; whenever you want to take it off just do the exact same thing in reverse, good to go. Do the same thing with the two inch ball and the pins do not come out they stay attached to prevent losing them. Then you just pop that in there and its solid. The shank diameter is one inch. The shank length is 2-1/4 inches.Again ball sizes are 2 inches and 2-5/16 of an inch.

They have a towing capacity of 10,000 pounds and a two year limited warranty. Now we're going to show you how this would work using our two inch trailer hitch demonstrator and one of our ball mounts. This is the convertible cushion ball mount for two inch trailer hitches and its available right here on etrailer.com, part number AMSC2.You would just put that through the ball hole, put your washer on first, then you would finger tighten that and then wrench tighten the rest. Slide that through, match your holes up, use your pin and clip, this is not included with the set but it is also available here at etrailer.com, part number PC3 or if you wanted a more secure attachment we also have a number of hitch locks that would work for this as well. Clip that off and you're good to go.That should do it for the Convert-A-Ball Interchangeable Ball Set, part number 904B.

The Convert-A-Ball #904b certainly appears to be a well-made unit. Made in USA. Rated at 10,000 pounds, it will not likely be the weak point in the towing combination. Very pleased with etrailer! 383452

I put this on my truck today. It is heavy steel and looks great. I need to use a 2 inch and a 2 & 5/16 ball for my large trailer. This is going to be a lot easier than changing my lock bar and replacing the entire slid in hitch. I have some chrome balls and they are already peeling off the chrome, these seem to be solid stainless steel. I am well pleased with the purchase and would recommend it to anyone. 339593

The convert-a ball set has a nice nickel finish. It comes with everything needed to install. After ordering the set I was contacted by etrailer stating that the set was not in their warehouse and it would take a few days to get it. I was asked if I needed it sooner or if I wanted to cancel the order. No need to as it showed up sooner than expected. Thanks for the follow up Wayne. 190649

Convert-a-ball has been excellent for decades and this latest ball system is no exception. I like the finish of this ball better than the old chromed ones which were slippery when snow covered and easy to drop when changing sizes in winter. If in doubt, get the nickel finish. 168222

I have one of these Convert-a-ball sets on each vehicle I own!!! They are very good, easy to swap and made out of high grade steel. I watched them test their balls and hitches at their plant during a visit many years ago. They test them to the MAX!!!!! All of their ball sets are made in the USA!!! at their SYDNEY NEBRASKA plant. They were the first with the changeable ball system and have it patented. All of the other types are imitators!!!! Some of the other changeable ball set are made in CHINA out of what kind of material I don't Know!!!!! BUY THE ORIGINAL!!! BUY THE BEST!!!! BUY MADE IN THE USA!!!!!!!!!!!!!!! 35427

Convert-A-Ball This site was really easy and fast to work with. I shipped on the cheapest option and the Convert-A-Ball 2"-2 5/16th kit came within a few days. I was amazed. Most places take forever, but these people really put a rush on it. The quality is solid, 10,000lb rating, and the ergonomics are outstanding. I had my old ball off and this on one in less than a couple minutes. The materials are heavy duty and flawless. I will tow 4,000-8,500lbs or more every day for the rest of my foreseeable future, so I am really putting my faith in this company. 5219

Ask the Experts about this Convert-A-Ball Hitch Ball

  • Availability of Interchangeable Trailer Ball Set That Features Wrench Flats on Shank
    The Convert-A-Ball Interchangeable Trailer Ball Kits do not feature wrench flats on the shanks. Our installers routinely use a large screwdriver through the ball retaining hole in the shank to prevent the shank from spinning while the nut is torqued. We offer a Tow Ready Interchangeable Hitch Ball Set, part # 63804. The shank does have wrench flats, a 2-5/16 and a 2 inch ball are included and the set has an 8,000 lb capacity that should be sufficient for your needs.

  • Can Replacement Balls be Ordered for the Convert-A-Ball Interchangeable Ball Set
    Yes, if you got the Convert-A-Ball Interchangeable Ball Set # 904B and later decided you wanted to also get the 1-7/8 inch ball you could get a Convert-A-Ball Interchangeable Hitch Ball 1-7/8 inch diameter # 300b. Or if you wanted to get all three balls at once you could order a Convert-A-Ball Interchangeable Ball Set # 900B. This comes with a 1-7/8 inch ball, a 2 inch ball and a 2-5/16. I attached a review video for this product for you to check out also.

  • Hitch Ball Recommendation Made in America
    I believe I have something that will work for you, but the Curt Hitch Ball # 40038 that you referenced is not made in the USA, it is made in China.

  • Is There A 2 Inch Trailer Hitch Ball Made In the USA
    The 2" Hitch Ball part # EH68C-C is made overseas but we do have a made in the USA hitch ball option for you, the Convert-A-Ball Interchangeable Ball Set part # 904B which gives you both 2" and 2-5/16" options. The majority of the trailer hitch balls are all made overseas. In regards to the Extra Long Ball Mount part # D-26, this does indeed have a reduced capacity due to the extended length but not by much. For reference, the Ball Mount part # C45310 is essentially a shorter version...

  • Can Shank Included w/ Convert-A-Ball # 800B Be Used With a 2-5/16 Inch Trailer Ball
    The 2-5/16 ball will fit on the shank of the # 800B, but because the shank portion uses a 3/4 inch threaded shank, it's not strong enough to tow a trailer large enough to be rated for a 2-5/16 inch ball. However, if you're just moving the trailer a few feet on flat ground, you can use a standard 2 inch ball of any kind if you wish.
