Order originally had Aug. 3rd delivery date, actually arrived Aug. 1st.
Have not used yet either the Ball Set or the Cushioned Hitch, but am familiar
with both products as already have used them for several years.

Pros - Excellent idea for not having to carry multiple hitches, easy to change different ball sizes.
Cons - Can be tough to tighten the locking nut (I used a large screwdriver through the pin slot to hold it while tightening with an impact gun), no included bag or case for the extra balls, balls rattle when installed.
Final verdict - I'm happy with the look of the stainless steel and that it won't rust. I would recommend this product.

This combo ball set is excellent...so easy to interchange the ball size and being stainless steel they haven't rusted and the steel itself is rugged and strong. It's truly the way to go if you have to change out hitch ball sizes.

Very good first impression. I read somewhere a tip about putting a screwdriver through the hitch (without the ball on it) to hold it steady while torquing it. That worked great! (why not include that tip with your packaging). I am currently only using the 1 7/8 ball with my utility trailer, but now that I have a truck, that opens up a lot of other possibilities and I'll be ready with the other two balls.

Have a set of these convert a ball and love the fact I don't have to have two or three different hitches or ball mounts for each ball. Or a ball mount that you have to rotate to get the ball size you need.

I have a small box trailer that has a 1 7/8" hitch, a boat trailer that has a 2" hitch, and a car trailer that has a 2 5/16" hitch. The Convert-A-Ball Interchangeable 3 Ball Set solved my problem. With out it I would have had to have a ball mount for each ball size. The Convert-A-Ball is a very good product.

Having this set of balls really help me out since I am changing trailers a lot of the time. I carry them with me in a small little ditty bag that I keep in the truck. I also keep the ball mount in the same bag because it's illegal to keep the hitch in the receiver when your not towing something.

I've used Convert-a-Ball for as long as I can remember. My last one was for my Subaru Outback, 1 7/8" and 2" only, chrome, and ended up wearing and rusting a bit, so I thought for my Grand Cherokee I'd go with stainless and add the 2 5/16" for a larger trailer I know I'll be pulling. Really like the product. Most everything I pull is about the same height, so just swapping the balls is great. I've even had a rare occasion where the 1 7/8" came to the rescue. The only improvements I would love to see are rather minor:
- A torque spec on the packaging instead of having to search for it, thankfully etrailer has that info on their site, and maybe my package was missing instructions.
- A way to put a wrench on it for tightening. Slipping a rod through the hole works OK, but not everyone has some sort of rod the right size and strength to do this. I suspect there is more than one bent ratchet extension out there.
Once installed, it is an excellent product.

The interchangeable hitch balls are a great time saver. No more wrenched to change ball from one size to another. Often I use the 2 5/16” and 2” multiple times in one day. Only need a knife point, a writing pen or a screwdriver to push the ball pin enough to pull the pin enough to remove the ball. Works great. Well worth the price.

Excellent product overall! I constantly tow various items that require different size hitch balls. This conversion ball system has made switching ball sizes extremely easy and a time saver. After a year of use there is little to no signs of wear. I would highly recommend this product to a friend!

I have been using "convert-a-ball" for about 25 to 30 years now, unfortunately, when
I sell the vehicle that it is attached to (after explaining to the new owner), the setup has always gone with the rig . . . I also always get the SS version of them, because of the add'l strength provided & the non rust feature. Wouldn't have anything else.
I still have the original "convert-a-ball" mounted on my 1977 J20 Jeep. Still in use!

Exactly what I wanted. Stainless is the way to go. I will say I have had this type ball before. (steel) the rubber o ring on the cross pin appears to be the only thing holding the pin in when not being used to tow a trailer. After 7 years the o ring rotted out and the ball bounced off. Lesson: when not in use keep it out of the elements and this thing will last forever!! Awesome product! E trailer has the best customer service around. Ordered online and had this in hand in 4 days! And that was choosing the cheapest shipping option possible!
Thank you E Trailer!!

Excellent product. My previous convert-a ball system was chrome plated but I much prefer the stainless . The chrome plating wears off after a few moths of use and you are left with a rusty hitch ball . The convert-a ball system is the ONLY way to go if you have multiple trailers with different hitch ball sizes. Great price and extraordinarily quick shipping from the good folks at etrailer.

These are very nicely made and well machined. I like the versatility this set provides for towing multiple trailers. I have a travel trailer that uses the 2 5/16 ball and a utility trailer that uses a 2" ball. I no longer need multiple ball mounts. Just swap the ball & go.

Excellent product. I have hauled a variety of farm trailers and just takes a few moment to switch. The ability to take the ball off and cover the shank has saved some pants from a lot of grease.

The hitch looks of high guality and hopefully will resist rust as it should being stainless steel. Only time will tell for sure.
The storage box is a "very nice to have" item to keep the loose ball sizes stored out of the way.

See what our Experts say about this Convert-A-Ball Trailer Hitch Ball
- Compatibility of Covert-A-Ball Interchangeable Nickel Ball Set with Aluminum Ball MountFor use with an aluminum ball mount, the Convert-A-Ball Interchangeable Ball Set in stainless steel # 902B is your safest choice and my only recommendation. Regardless of which ball size you use, the weight capacity will remain at 10,000 lbs when used in conjunction with its 1" solid shank. If you were to use the nickel ball set # 900B you referenced, the dissimilar metals coming into contact with one another can cause a reaction risking damage to the aluminum ball mount and eventually...
view full answer... - Availability of Convert-A-Ball Interchangeable Trailer Hitch Ball w/ 1-1/4 Inch Diameter ShankConvert-A-Ball doesn't offer their Interchangeable Trailer Ball Sets with a 1-1/4 Inch diameter. If you're wanting to use a ball mount with a 1-1/4 inch hole for the trailer ball, you could use a Hitch Ball Bushing like # 58184, which would allow you to use a 1 inch diameter shank trailer ball in a ball mount with a 1-1/4 inch hole. This would allow you to use the # 902B Stainless Steel Interchangeable Ball Set or if you prefer nickel plated, you could use # 900B. Keep in mind that using...
view full answer... - Comparing the Nickel Plated and Stainless Steel Convert-A-Ball Interchangeable Ball SetThe stainless steel construction of the Convert-A-Ball Interchangeable Ball Set part # 902B is going to be much more weather resistant than the nickel plated steel of the Convert-A-Ball Interchangeable Ball Set part # 900B. There shouldn't be any rust inside the pinhole with the stainless set however, dirt and grime can still get inside and cause the pin to stick which can be present on both the stainless and nickel plated options therefore, I recommend using the Convert-a-Ball Cover part...

We have a torque wrench that would work part # ALL944001.
view full answer... - Nickel and Stainless Steel Versions of the Convert-A-Ball Interchangeable Ball SetWe do in fact have both a nickel and stainless steel version of our Convert-A-Ball Interchangeable Ball Set - 3 Balls - 1" Shank. The nickel version is part # 900b and is the more economical of the two. The stainless steel version is part # 902B and offers much better corrosion resistance. I've linked to a video review of these sets for you to look at.

The Convert-A-Ball Interchangeable Ball Set # 902B comes with the 2-1/4" standard shank length so it's the kit you're looking for. The XL kit, part # 105TB, comes with a 3" shank length just or reference. Then to wrap up the rest of the parts you asked about you'll need the Storage Case # 004B and the Cover # 005B.

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...

This multi-ball part will fit properly on a ball platform up to 1-1/8-inches thick. I confirmed this with Convert-A-Ball. This item is rated for 10,000-lbs towing no matter which ball size is installed. For example, the Convert-A-Ball Ball Mount Class IV Ball Mount # AMSC2 has a...
view full answer... - Trailer Hitch For A 2022 Hyundai PalisadeYes, the Curt Trailer Hitch # C13427 does fit your 2022 Hyundai Palisade. This hitch is a class III trailer hitch and has a maximum towing capacity of 6,000lbs. To complete a towing setup, you'll need wiring # CU94FR, and a ball mount # C45030. Additionally, you may also need a hitch pin and clip # C21510, and a ball for the ball mount. I recommend the Convert-A-Ball # 902B that has a 1-7/8" ball, a 2" ball, and a 2-5/16" ball.

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.

The advantages of a 2 inch, Class III hitch are, as you have pointed out, greater weight capacity, more options for accessories, and you will be able to use weight distribution if you wanted. I have included a link to the installation details and a video installation below. You will also want to check your owners manual for your vehicle towing capacities. The...

First you would measure from the ground up to the top of the receiver opening on the trailer hitch. Then, with the trailer level, measure from the ground to the bottom of the coupler.

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...

Good, Ive used the mid-sized ball a couple of times as well as the 1 7/8 a lot and it works fine.
