Video Transcript for Convert-A-Ball Hitch Ball - Trailer Hitch Ball - 105TB Review

Today we're going to be taking a look at part number 105TB, this is the convertible, interchangeable ball set. It's going to include one extra long shank as well as three heavy duty interchangeable hitch balls and the necessary hardware to get everything tightened down appropriately. It's made from a steel construction, and it's going to use a nickel plating technology that's going to produce a strong, protective finish. It's going to offer great coverage over the entire unit, it's corrosion resistant, rust resistant, it's non-magnetic and it is stain repellent so it's going to stand up well against the elements. Now that technology is a eco-friendly plating method that's going to be less harmful to the environment than traditional chrome electroplating methods. The unit's made right here in the USA. Real quick I just want to go ahead and show you how to assemble the unit together.

You can pick whatever size hitch ball you need, you're going to get a 1 7/8 inch ball, you're going to get a 2-inch ball and you're going to get a 2 and 5/16 inch ball. So let's just go ahead and take the 2-inch ball, it's going to have a little pin right here in the middle, so simply just find something small enough that you can use to push that pin out. It will not come out all the way, so that way you don't ever have to worry about losing that. You can place it directly over the end portion there and then slide the pin back through. It's totally secured on there until you push it back out and need to interchange the balls. That's how you place it on whatever size hitch ball need.

Again, you're going to get three different sized hitch balls. The shank on this unit is going to give us a diameter of 1-inch, so this is designed to fit into a 1-inch diameter ball hole. It's going to fit ball mount platforms or draw bar thicknesses from 1 and 1/8 of an inch thick to 2 inches thick. The shank length on this unit, measuring from the bottom of the platform to the end, this point here is going to be about 3 1/2 inches, so the end of the threaded portion is about 3 inches. It's going to offer a towing capacity of 10,000 pounds. Once you have this on your draw bar or ball mount, lock washer goes on followed by the nut. Then you will need to get that torqued down and then simply place the cotter pin in there, then you would bend it, just as a safety back up.

Really easy system to do and then when you're ready to change it to a different size hitch ball, simply pop that one off, grab whatever one you need and place it on there. It's really fast to interchange the different sizes. That's going to do it for today's review of part number 105TB, this is the convertible, interchangeable ball set.

This is the 3rd set I've purchased, 1 for myself and 2 as gifts. Everything in one spot!! Quality construction. Item to be used on Chevy 2500 that spends a lot of time pulling trailers. Thanks. 211855

Good morning Rachael. The Convert-A-Ball is holding up great. I dont use it every day, but on the average of every couple of weeks. I have multiple trailers with the 3 different sized balls, this produce makes it easy and fast to switch from 1 to the other. Thanks.

I could not find any bumper " hitch balls" that would fit correctly my 07 Dodge 1500 Ram P/U. It came with the tow package , over drive, except a ball on the bumper itself. when I searched nobody had anything with a long enough shank to properly fit my factory support tow bumper. I found you guys and my problems are solved. Work s great and I have an assortment of ball sizes to choose from. 711079

Bought this for my 06 dodge ram 1500 that had an extremely long collar on the bumper hitch. it is strong and well made and definitely long enough to go thru the collar on the bumper. I'm very glad a search led me to your site I will come back here every time I need any trailer needs!! I sent an email question to e-trailer and they responded within 12 hours and let me know that I had made the right choice for my needs and followed up with tracking # it showed up exactly when it was suppose to. all in all great place to do business. 669615

I had already owned these products my vehicle was rear-ended and the drawbar was busted off and ball disappeared so they had to be replaced after the collision and I've never had a problem with them because they're made great 604664

Delivered as presented and sent quickly. Nice quality service and the Convert-A-Ball was as well. I would buy again. 598198

Product was almost what I expected, but the price and shipping were great. I can now see in the picture that it appears the nut and washer are not stainless as everything else is. I was surprised when it was delivered and they weren't stainless. There may be a reason for this but if there is I'm unaware of what it could be. 582224

Keep it under the seat when not in use. When it remains on the truck for extended periods I use a ball cover. I keep it lubricated and hasnt been a problem in any way.

I can't be more pleased with etrailer's services! This was my second order, and I must say that the etrailer videos are part of the reason for the 5 stars. They are done in ways that make them helpful to the customer in comparing products, being sure what is being ordered will be right for the application, and in the case of wiring, exactly how to do the installation. The product arrived right on time, well packaged, and fit my truck just as expected. Excellent follow up after the order, and through the tracking process all the way to delivery as well. Super supplier! 450354

I havent used the equipment as often as expected, but you can mark me down as still very satisfied. Thanks

Just received the product by mail yesterday, (4/23/2015) and have not applied the product as of yet. I must admit, it arrived in a timely manner and from looking at the package, I'm very much pleased with my order. I will be doing business with you guys again. After applying the product, I will shoot some pic's of my project. 187912

This product is absolutely wonderful. It is difficult to find a 2" hitch ball capable of towing 10,000 pounds. This one is, plus I have the option of going up to the 2 5/16 ball if I need to tow more. This hitch ball has more towing capacity than my truck! I higlley recommend this interchangeable hitch ball set. 181726
