Video Transcript for etrailer Ball Mount Kit Review

Adam: What's going on, everybody Adam here with etrailer. Today we're going to be taking a look at the etrailer 2-1/2 inch trailer ball kit. This is a nice kit that we put together that pretty much gives you everything you need to haul some heavier duty stuff. We can go with a rise, we can go with a drop, and we have two different kinds to choose from.Now let's go ahead and see how it looks when we hook it up to a trailer. Do you have a trailer that has a high coupler, like a dump trailer or something else like that This might be really good for that. But for all the trailers we have here at etrailer, it is a little bit too much of a rise for what we really need, but that's why we give you two options.

If you don't have a lifted truck, I would definitely recommend getting the 1-1/2 inch rise and 3 inch drop ball. This is a 2500 stock Silverado, and this is definitely the one we're going to be using, but if you do have a little bit of a lift, it's probably best to go with the 5 inch drop and 3-1/2 inch rise.Between the two kits, we're going to have one differentiating factor, and that is just going to be the shank itself. One is going to have a 1-1/2 inch rise or a 3 inch drop. The other one is going to have a 3-1/2 inch rise or a 5 inch drop. Both are going to be made for a 2-1/2 inch class five hitch with a gross trailer weight of 18,000 pounds and a trailer tongue weight of 2,000 pounds.

Both are going to have an overall length of 15-1/2 inches, and then from the center of the hitch pin hole to the very end, it's going to be about 11-1/2 inches. And then from the center of the hitch pin hole to the center of our ball mount hole, it's going to be about 10-1/4 inches. It is made of one solid piece, and it is going to have a nice powder coated finish, so it's not going to rust away on you over time.Both kits will come with a 2-5/16 inch ball with a gross trailer weight rating of 20,000 pounds, but we want to make sure that we don't exceed the actual ball mount here, which is 18,000. The shank of our ball is going to be 1-1/4 inch in diameter, so it's nice and tight. A little bit of wiggle room, but that is okay.

And the overall length is going to be about 2-3/4 inches.We do provide a pretty durable canvas bag for you, has a little holder here. And with the ball mount completely assembled, it's going to be able to fit in there with ease with plenty of room for your hitch pins and anything else that you want to fit in here. If you needed an 1-7/8 inch ball or a 2-inch ball, we do have a lot here to choose from at etrailer, but just make sure that you don't go over the ball's capacity, as the shank is going to be a little bit tougher than the smaller ball size.One thing that doesn't come with the kit is a hitch pin and clip. We do have a lot here at etrailer. So this one here is going to about 5-3/4 inches long, and it fits just perfectly through the 2-1/2 inch shank to where you can get this pin inserted in.

But in my opinion, what I do with any hitch-mounted accessory is grab a lock. So the etrailer lock is 5/8 inches in diameter, fits nice and snug in there, and this is going to lock it to your hitch receiver so it doesn't run off. The mounting hardware is included. We're going to get a lock washer and a big old nut, but the tools are not included, so what you're going to need is either a wrench or a socket. That's going to be an inch and 13/16ths inches. And I would definitely recommend getting a breaker bar to lock this thing down, because we're really going to have to torque this tight. I would go ahead and insert the ball mount. This one is the 2-inch drop. And get her locked in place.And that's just about it for a look at the etrailer 2-1/2 inch trailer ball set..

etrailer Ball Mount Kit


It’s a beefy hitch that ought to handle anything I want to pull.


Thanks etrailer. .fast friendly. Looks good. Get job deal the part I can call talk to real person and take my order. .I will be back again. .have 2014 Ram 3500 dually nice fit looks strong.


Well made super strong ball and hitch. The carrying bag makes storing the unit in my camping trailer very convenient. Excellent value.

Glen S.


Used the unit to tow my 26 foot camper trailer on a 4000 mile trip this past winter. Worked well. I didnt worry about the connection between my truck and trailer.


This is a very stout product that instills confidence. The 2.5" size of this ball mount fits perfectly in my Chevy 2.5" hitch. I tow 10K+ pounds regularly and I'm much happier using this 2.5" instead of 2" ball mount with a sleeve.

I used the 3" drop version of this part for three years and had no issues so I decided I would try the 5" drop for my new truck (lifted this one slightly higher).

If I had one complaint (it isn't really) it's that the ball mount itself seems to have been ground on with a grinding wheel prior to being finished. This makes the finished surface of the drop arm rough and uneven. It works fine, but I'm a little OCD and I feel like for $90 I should get a part that looks as good as it performs.


Ball mount is solid and heavy. Purchased for use with a smaller cargo trailer, so the weight rating is overkill. I didn't want to use the 2" adapter on the receiver so I purchased this 2.5 inch mount. Fits nicely and am sure that it will hold up to whatever I throw at it. The chrome coating on the ball started wearing off after the first couple of hundred miles.


Awesome package....I really like the combination package with carrying bag. eTrailer did an awesome job delivering the package....quick and accurate. I'd definitely recommend this to anyone needing a Class V Ball Mount.

The e-track and accessories are just as described and an awesome price when compared to other stores. Thanks eTrailer


This ball mount and ball are the definitely heavy-duty. The bag, not so much. After one use, the ball has already lost a good bit of its chrome (I HATE chrome!), but will continue to function fine. Grease... The bag is only so-so, but does keep everything together nicely when not mounted in the receiver. Just wish it was made in the USA instead of China.


Fits perfect in my late model 2012 F350 factory receiver. This monster ball mount gives me the peace of mind that I can safely tow anything I want. I am very happy with this mount.

Bag is nice, but would like to have a horizontal handle as well.

Shipping was very fast.


Great product no problems with 15000lbs


Great product, I just hope I got it low enough to level the trailer.



Its a well made and heavy duty product. It is a little longer than I needed but that is all right.


Great value for a Ball Hitch mount, super heavy duty ...


receiver paint coating chipped to base metal, heavy duty kit should include the needed pin at this price point.


Exactly as described. No problems with fit and quality. 2013 Ram 2500 6.7 cummins


Had them for a year and still working great. I highly recommend etrailer. They’re a great company to work with. they actually care about the customer.


Perfect fit for my 2011 2500HD duramax and quality is very good. Drop is perfect for stock ride height. Solid and Heavy. Best part was help from George J who proactively reached out to make sure it would reach me in time. Service like that is rare based on my ordering from other online retailers.


The items shipped quickly, and were packaged well. I would definitely use E trailer again


Excellent product. Customer service was exceptional. I will definitely order from etrailer again and recommend them to all my family and friends.


Delivered sooner than expected and great products just like every other time I have ordered from Etrailer. Would definitely recommend to anyone!


As advertised, have used on several occasions and very satisfied with the item, I use it on my 2015 GMC Denali 2500HD.


This baby is sooo solid you could use it to bench press! Came in a reasonable amount of time, was all it was described to be. Good product at a good price. I will shop with these folks again when I need something.


Great value on this item. Installed and top notch quality.


performs as expected
fit well


Works great......good quality


Item was as described. Good Quality. Speedy delivery.

    The ball that is included with the Ball Mount Kit # EBMK25518 that you referenced is a 2-5/16 inch ball. In the second bullet point of the description that info is listed. The diameter of the shank is 1-1/4 inches and 2-3/4 inches long. Since this is sold as a kit and all the parts are compatible this information wasn't as easy to find. In the second bullet point the part number for the ball is listed (part # 63840) and on it's product page this info is listed.

  • Can a Ball Mount for a 2-1/2 Inch Class V Trailer Hitch be Used in the Rise Position
    Depending on the ball mount, you can use it in the rise or drop position. Some ball mounts, like # 45291, can only be used in the drop position. The Reese Titan Ball Mount, # RP45323, that comes in the etrailer Ball Mount Kit, # EBMK25518, can be used in the rise or drop position. It will provide 3-1/2 inches of rise or 5 inches of drop. I have included a link to our FAQ article on choosing the right ball mount for you.

  • Ball Mount with 5 Inch Drop Needed to Tow Trailer Level
    Usually the tongue weight of the trailer will pull down the rear of the vehicle a little and it is possible it could be enough to make the trailer level. If that does not happen then I do recommend going with a ball mount with more drop. For a fixed ball mount I recommend the Ball Mount Kit for 2-1/2" Hitches - 3-1/2" Rise or 5" Drop - 18,000 lbs # EBMK25518 . If you have a 2 inch receiver than an adjustable ball mount such as # C45900 is your best option. This one has a...

  • Recommended Class V Trailer Hitch For 2011 Ram 3500 Pickup
    The trailer hitch I recommend for your 2011 Ram 3500 is the Draw-Tite, part # DT45518. This is a Class V hitch and it has a 2-1/2 inch receiver opening. Per the attached instructions no mention is made of a bumper so it should fit just fine. You might also be interested in a ball mount kit like part # EBMK25518. This has a ball mount that features a 3-1/2 inch rise or a 5-inch drop and also includes a 2-5/16 inch hitch ball. For a hitch pin lock I recommend part # e98881.

  • Will Draw-Tite 2-1/2 Inch Trailer Hitch Fit a 1997 Dodge Ram 3500 Dually with Step Bumper
    A roll pan bumper will not have any sort of step on it. A regular bumper will have that center "step" where the license plate sits. It sounds like you have a standard bumper so you would not have to worry about that at all. I have linked a help article that shows drawings of different bumper styles. Some of the fancier trim models of the later Rams might have come with a roll pan bumper, such as a Rumble Bee or some version of the Sport. I also recommend etrailer ball mount kit # EBMK25518....

  • Why Wont Ball Mount Kit Fit Ford Factory 2-1/2 Inch Hitch Receiver
    The reason the Ball Mount Kits for 2-1/2" Hitches - 3-1/2" Rise or 5" Drop # EBMK25518 (as well as 1-1/2" Rise or 3" Drop # EBMK25318) will not fit the factory 2-1/2" hitch receiver on your 2018 Ford F-350 is that those receivers have edges which are a bit rounder than standard hitch receivers and this ball mount has square edges. I recommend checking out the Titan Ball Mount for 2-1/2" Receivers # 45123 which has a 5" drop and from the accompanying photo you can see how the...

  • Ball Mount, 2 Inch Ball, and Storage Bag for a 2013 Ram 2500 with 2-1/2 Inch Trailer Hitch
    We do not have a ball mount kit with a 2-1/2 inch ball mount and 2 inch ball but you can get those items separately. The ball mount that is used in the kit you referenced is # RP45323. For a 2 inch ball with a 1-1/4 inch diameter shank you can use # A-90 rated up to 10,000 pounds. And the storage bag is # ETBMB. Getting these parts separately will actually save you a couple of bucks!

  • 2-1/2 Inch Trailer Hitch for a 2000 GMC K3500 Dually
    For GM 2000 was a split model year. Prior to 2000 the trucks were either a C series for 2 wheel drive or K series for 4 wheel drive. Sierra was not a model at that time; it was just a trim level. In 2000 there were both C or K models and Sierra models but only for 1500 and 2500 series. In 2000 the 3500 would still have been a K3500 meaning that none of the hitches for the 2000 Sierras will fit. So for a 2000 GMC K3500 you can use 2-1/2 inch hitch # DT45506 as long as the truck is a long...

  • Recommended Class V Hitch for a 2022 Ram 3500
    I would be happy to help you find a hitch for your 2022 Ram 3500. It looks like your 30’ Airstream International has a maximum capacity of 10,000 lbs. I have a couple of options for you depending on the bed length of your truck. All of the hitches with the capacity you are looking for require drilling for installation. If you have an 8 foot bed with or without the factory hitch you will want the Draw-Tite item # DT45518. This hitch is custom fit and bolts directly to your Ram 3500 with...

    Yes, the EcoHitch Hidden Trailer Hitch Receiver # 306-X7196 that you mentioned will fit a 2004-2009 Toyota Prius.
