Video Transcript for Convert-A-Ball Hitch Ball - Trailer Hitch Ball - 802B Review

Today we're going to review part #8072B. This is the Convert-A-Ball Stainless Steel Interchangeable Ball Set with the 1 7/8" diameter hitch ball and a 2" diameter hitch ball. Now this hitch ball set will allow you to easily switch between these 2 different size hitch balls without having to use a heavy wrench to remove the hitch ball from the ball mount. Basically, what you do is just by removing this integrated pin in the hitch ball, you can see the side that has the dimple in it, if you just push on it, it'll pop out the other side. This integrated pin if you just pull it out, you can interchange whichever ball size you need. I'm going to show you in a minute how this works.

Now this part does include the 2 heavy-duty interchangeable hitch balls, the extra long shank with the lock washer, the nut, and the cotter pin. The cotter pin is used once it's torqued down to put in for security. Now this hitch ball will stand up to the weather and the moisture. It used the quality and durable of the pure stainless steel construction. This part is made in the USA. Again, the specs on this, this is designed to fit ball mounts with a 3/4" diameter ball hole.

This drops into the ball mount. Now 1 note I just want to mention to you is the diameter in the mounting hole in the ball mount must not exceed the diameter of the ball shank by more than 1/16". What I'm going to do here is give you a few dimensions on the shank. The shank measurements are the most critical on the hitch ball. We'll go ahead and take the nut and the washer off.

The diameter of the shank is going to be right at 3/4". The shank length, this is a extra long shank, so the shank length on this is going to be 2 1/2" and again, the ball sizes is 1 7/8" and 2". Now also another note is for safety reasons, they also make a 2 5/16" interchangeable ball, but it will not fit on the 3/4" shank for safety reasons. The hole is a little bit different so to keep somebody from putting a 2 5/16", which is made for heavier loads on this shank, they do that. Again, the towing capacity, which is stamped on here, is 5,000 pounds. Just to show you basically, so what you would do is take your ball mount, that has the mounting hole, drop this into the ball mount.

Go ahead and put your lock washer underneath, put your nut, go ahead and torque it down to the specs. Once you get it torqued down, take your cotter pin, install it for security. Once that's installed on there, then all you have to do is if you're going to tow a trailer that requires a 2" diameter hitch ball, just again, go to the side that has the dimple, push on it, it'll pop out the other side, and what's nice is these pins are made to stay connected to the ball. They don't completely come out, so you don't lose them. The other nice thing is they do have a nice o-ring on the end, so when you do push it all the way in, it'll actually seal that and keep any dirt or debris from getting in there and causing the sliding action to be worse. Basically with it completely open, you just line it up to the hole on the shank, push her all the way through until it's flush on both sides, and there you have a 2" hitch ball. Now if you all of a sudden need to tow a trailer that requires a 1 7/8" hitch ball, again, instead of having to take the whole hitch ball off the ball mount, just go the the side that has the dimple, push on it, pull the pin all the way out, slide the ball off, take your 1 7/8". All the hitch balls are marked on top with the diameter. 1 7/8" and 2" on this one, again, pull the pin all the way out, line it up to the hole, push it all the way until it's flush. Now you're all ready for the trailer that's a 1 7/8" hitch ball. Pretty simple process, but that should do it for the review on part #802B, the Convert-A-Ball Stainless Steel Interchangable Ball Set with the 1 7/8" diameter hitch ball and the 2" diameter hitch ball. .

Great product if you get the stainless steel model. I have been using this product for around 30 years. The first one I had only lasted 10 years as I was not paying enough attention to is the ball got rusted to the shaft and I never got it off. The second one I got was stainless steel and it has been working as well today as 20 years when I bought. This one I bought for my trailer dolly as all the trailers I hook the dolly up to are not the same ball size 665324

The hitch mount and ball look to be of high quality and exactly what I needed for my bumber mount. Being able to easily switch between ball sizes will save work and wear on both the hitch and vehicle . I will be using it this weekend. I want to comment on the service and responsiveness of etrailer.com. This is part of my second order in two weeks and the ordering, shipping and company interest in customers is outstanding. I was also pleased to learn that etraier.com selld RV/Motorhome parts. I will be back. Please keep up your high quality service. 614915

Have used these before and am well satisfied with the product. On the trailer end of the process, delighted with the selection of products- was able to get the 3/4" shank size ball hitch with no hassle. Other sources would have only the larger size shank. Service was excellent and fast shipping. Definitely going back for other products. 390031

still doing a great job with the different trailers we have and the different ball sizes, makes it easy to hook up to.

Use these balls on my ATV to pull trailers, wood chipper, leaf vac, etc around our property. Wonderful to just swap the balls with a pin rather than having to un-bolt and re-bolt another ball. 320648

Ordered this for my husband. He has to change the size of the hitch ball often between the boat trailer and the lawn tractor trailer. Works great and makes life a little simpler! 214163

I have used Convert-A-Ball products for years and they are the best. Very high quality, terrific convenience as I pull various trailers with different size hitches - would recommend them to anyone. And, they are Made in the U. S. of A. - something very important to me. 212112

The convert-a-ball set and the storage container came promptly and well packed. This is not my first purchase from etrailers, their prices and product always impress me. I can't find a better price nor a better selection locally, even if I go all over town looking.   The main shank where the ball goes on needed a little cleaning where the pin goes through. The hole was left kind of rough on the inside. I cleaned it up a little without changing the size of the hole, just for piece of mind. I wasn't sure of what the rough edges and small fragments of metal would have on the pin during use, outside of that, I was impressed with the product and look forward to using it. 166211

Wiring Harness, Hitch ball and lock all excellent and good quality. Installation was flawless. Will recommend to anyone looking for good value and timely response with questions about delivery and product. 144160

This is the second Convert-A-Ball set that I have purchased, to use with my wife's new SUV. It is handy to be able to switch between 1-7/8 and 2-inch balls without having to wrench off one ball to put on another, and it takes up far less room than having a drawbar for each size ball. This model has only a 3/4-inch shank and cannot mount a 2-5/8-inch ball for safety reasons. My wife's Subaru Forester has a roughly 2250lb tow limit, so not having the big ball is not an issue. Both this unit and the one I obtained previously from eTrailer were the stainless steel versions. As we live in the northeast, road salt and salt water do take their toll. This system is easy to use and saves a lot of space - I highly recommend it for anyone who uses a drop- or riser-type drawbar, or (in the case of my station wagon) a weight-distributing hitch, as it greatly increases your flexibility for towing different trailers at need. the balls swap quickly and fairly effortlessly. I find it worth the investment! 94674

Product arrived well packaged and installs and operates as represented. Looking forward to seeing how it holds up over time. 49024

Bought the Convert-A-Ball set - only place I could find that had a decent price on the 3/4 shank SS bal - fits and works like advertised. 42683

I had a earlier Chrome version. It used a 1" shank, hence the need for replacement. I chose stainless because the added cost will save time and trouble should the new nickel-plated version not last. These are the most secure convertibles, for the design is impervious to dislodgment (the worst that could happen is the pin riding against a coupling should it move, without allowing the trailer to disengage from the hitch). Two considerations: it would be nice to inform the customer that the attaching nut requires a 1 1/8" socket, and it would be better to machine a recess on the base to permit use of a wrench to hold it when the unit is being secured (as it requires 180 ft lbs to attach. Overall a superb product. 35288

Had the steel version for years and ordered this one for my car because the older Convert-A-Ball was a 1" shank. Sold that vehicle but kept the Ball set. This new one being stainless will look good for years on the car! 34277

  • Interchangeable Hitch Ball Recommendation For 2001 Keystone Camplite Pop-Up Camper
    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...

  • Availability of Replacement Shank for Convert-A-Ball Interchangeable Trailer Ball System
    We do indeed offer replacement shanks for the Convert-A-Ball interchangeable trailer ball system. For a shank with a 3/4 inch diameter shaft, the # 104B with a 5000 lb capacity or the # 101B with a 3500 lb capacity is available. Neither shank is compatible with a 2-5/16 inch ball, as the weight capacity of either shaft is insufficient for a trailer that would use a 2-5/16 inch ball.

  • How To Get VIN For 8 X 20 Trailer
    It sounds like you have done the things necessary to get the VIN for your 8 X 20 trailer. Normally the VIN is located inside one of the frame rails near the front of the trailer. I recommend taking the paperwork to the local state license office and ask what is needed. They may have you take the trailer to a highway patrol facility so it can be inspected and assigned a new VIN.

  • Is Ball on Curt # C45571 Euro-Style Ball Removable
    The Curt Euro-Style Class II ball mount you referenced, part # C45571 features a permanently attached 1-7/8 inch trailer ball which is not removable. If you were wanting a ball mount with a similar rise where you could interchange the trailer ball, I'd recommend going with a standard type ball mount, like part # C45017. If you anticipate needing to change between 1-7/8 and 2 inch trailer balls frequently, I'd recommend using a interchangeable ball set-up like what Convert-A-Ball offers....

  • 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.

    For your 2011 Honda Civic Sedan the Draw-Tite part # 24763 that you referenced has been confirmed as a fit. Since this is a Class I hitch like all of the hitches for your vehicle you would have to use the recommended ball mount with the hitch, part # 3593. For an interchangeable ball set to fit the ball mount you would want the part # 802b. For trailer wiring you would want the Curt hitch part # C56011.

    The first thing you will want to look at is the diameter of the ball hole in the ball mount you use. Some of the interchangeable ball sets we carry that have a 1-7/8 inch ball will fit a 3/4 inch diameter hole and some fit a 1 inch diameter hole. If you have a 3/4 inch diameter hole I recommend kit # 802b because of the stainless steel construction. It won't corrode or wear away like chrome. If you have a 1 inch diameter ball hole then I recommend # 902B for the same reason; stainless...
