Video Transcript for Curt Forged Ball Mount Review

How's it going everybody Clayton here at Today, we're going to be checking out the Curt Forged Ball Mount for two and a half inch hitches. Now this ball mount is going to be pretty awesome because it's going to be a solid shank. Now, this is what it's going to look like when it's installed on our hitch. And I do suggest picking up a locking pin, you can find those here at etrailer. That's just going to help protect our investment.

This is what our ball mount is going to look like whenever it's not being used in our vehicle. As you can see, it's pretty beefy, and that's good. We're going to get a really high weight capacity. But we'll get into the weight capacity here in just a second. But taking a look at the end of our ball mount, you're going to see that there's no opening.

That's going to be because it's forged out of a solid piece of metal, giving it a lot more strength. A lot of the other ball mounts out there on the market, are going to have an opening back here in the back, and that's just going to be a point of failure, because whenever these start to rust, that's a really good area for that rust to get in there and really corrode our ball mount. So like I said, this ball mount is going to give us a really high weight capacity. As far as towing, we're going to have a 20,000 pound towing capacity. So that's going to be how much the ball mount can actually pull.

We're gonna have a 2,700 pound tongue weight rating. Now chances are that this ball mount is actually gonna be rated a lot higher than your vehicle. So you need to check with your vehicle's owner's manual, and make sure that it's rated to tow at these capacities. If there is a difference, always go with the lowest number between the two. And this weight capacity is going to vary on which ball that you have installed.

Our ball mount isn't going to come with an actual hitch ball, so you will need to pick one up here at etrailer, whether that be two inch or two and five sixteenths. We can now take a closer look at our ball mount. You will notice that the finish is quite a bit different on here than your traditional ball mount. And that's because this is going to be a black carbide finish. And the black carbide is going to hold up to rust and corrosion and a lot better over time, and that's just going to extend the life of our actual ball mount. Now when you do compare that to a lot of other ball mounts or any hitch mounted accessories out there on the market, they're going to use a black powder coat or some sort of powder coating and finish. And powder coating is good, but the problem is when ever that rattles around in a receiver tube opening, it's going to knock off some of that powder coating, creating a place for rust. That's what really is so good about this black carbide. It's just so much more durable, and I really just like the way that it looks. And our ball mount is going to use a standard five eighths pin. So that's really nice because they're very common. And as far as installing our ball mount into our receiver tube opening, it's going to mount just like any other hitch mounted accessory. Simply just slide it in until your pin hole lines up. Our ball mount is going to give us a four inch drop. That's going to be four inches from the top of the ball mount here, down to the platform. This is very important for whenever you're pulling a trailer because you want that trailer as level as possible. So you just want to make sure that the four inch drop is going to be appropriate for your trailer. And if you do need to use this in the rise position, we are going to get a two and a half inch rise. And another important dimension of our ball mount, is going to be from our pin hole opening to the center of our ball. And in this case, it's going to be eight and a half inches. You just want to keep that number in mind if you're using it on anything that has a bumper that kind of hangs over, just so you know you have enough ground clearance. And as far as the dimensions on the ball, you're just going to need to pick up a ball that has an inch and a quarter shank. That way, it fits nicely into the platform of our ball mount. You can find a whole lot of options here at etrailer. This is going to be a great option for you guys that are pulling the same trailer all the time. A lot of the adjustable ball mounts out there have a lot of moving pieces, a lot of things to lose or break. So if you do happen to be pulling the same trailer, this is probably going to be the best option for you. And with our coupler locked down, we're now ready to hit the road. That's going to do it for our look at the Curt Forged Ball Mount for two and a half inch hitches..

The ball mount and stainless steel ball are exactly what I wanted. This is a 3" square hitch, so pretty heavy stuff. It is finished nicely and I'm looking forward to seeing it on my truck tomorrow morning. The shipping was free and arrived in time for the weekend! Could not be a better way to do business. Thank you.


Product came through exactly as advertised and it is of high quality. Fast service with prompt delivery.
The sales lady was very helpful and knowledgeable with the three products I ordered. I recommend using etrailer for your trailer parts.


My first experience etrailer and products they offer. Gotta say, I ordered the wrong item and no issue for the return process...... They also appear to only offer the best quality products. Very happy to this point and they will be my go to source for towing related parts.


This product was easy to look up and delivery was in a timely manner. Very happy with Etrailer every time I ordered from them.


Great price, easy to order, excellent quality, fast delivery. Thank you.


very good service



Good heavy Hitch


Just your basic ball mount, the product is just like most 2” Hitch ball mounts, the service wasn’t very good though.
Ordered on June 15th (product was in stock) took them 6 days to send it out, took another 6 days in shipping and got all the way to my post office two days before leaving on vacation (I needed it for the vacation) and the post office said “box was empty and they notified seller” etrailer sent a new one (got here a week after my vacation) in a damaged box (packaging is horrible, little bit of paper in a box with a 5 lbs ball mount) almost lost this one too.
I don’t believe I’ll be using etrailer in the future (had issues before)


Looks & works great. Easy to install. Make sure you order or have a locking pin and ball to go with it.


This is a great all-purpose hitch. I've used it to mount a heavy-duty bike rack and a steel T-rack to carry a canoe as well as lumber. Most recently I hauled 5 x 8 cargo trailers full of plants, then furniture for a 600-mile move. It was simple to use, problem free, very strong and sturdy. Now that I live on some acreage, I see a trailer in my future, so this will get a lot more use. I drive a 2013 Tacoma, so this is a good size hitch at a good price with sufficient capacity for my needs. I do use a key lock for the hitch as well.


I have two of these. My first I bought two years ago. I very highly recommend this Curt Class III Ballmount 2" Drop because of its price, durability and quality. I towed various class 3 loads with ease and confidence with this ballmount. It slides into the hitch and does its job without fail. It looks excellent after towing a load.

etrailer's price is about as good as it gets and delivery is very speedy.


The one foot ball mount works great on a 2014 Chevrolet Silverado work truck(no lift kit). We use it for a one axle, lawn care/utility trailer. It is used at least half the work week and has held up for a year. It may not be a good choice for a heavier trailer, but at that point we would also purchase a 2500 truck too. The mount helps clear the jack when the tailgate is opened with about 2 inches to spare.


Our problem: back lift gate on our Subaru Ascent SUV would not clear the powered tongue jack on our Casita trailer. Technical person on the phone suggested this this extended ball mount was just the solution and has served us well. Easy to take on and off. Sturdy. No problems for > 9,000 miles of towing this year.


I just opened up my new Class 5 Curt XD hitch and have not yet installed it so my comments are based on first impressions only. It is very heavy duty - and heavy at 40 lbs. - made of extremely thick metal and outfitted with quality Grade 8 bolts with square necks so they won’t turn when torquing on the nuts to attach the main tube to the side mounting plates. My bolts are plated yellow (which I like) rather than silver as you may have seen in some online photographs. It is substantially beefier than my existing Grade 4 hitch and superior in every way. It’s an impressive piece of hardware. I cannot imagine anyone being disappointed with it on specifications, quality, strength, and general appearance. It’s a beast. What I AM disappointed in is Curt’s packaging and the condition in which the hitch arrived. (This is NOT a reflection on as the hitch arrived in Curt’s original packaging.) The unassembled main tube and the two side mounting plates come bundled together with nothing separating them but shrink wrap. No cardboard, plastic, even paper coming between the metal surfaces - just shrinkwrap probably not even a couple of mils thick. With basically metal-to-metal contact in an oversized-box with the bundle jostling around, it would be a miracle if there were no scratches, gouges, or some type of damage to at least one piece, which is exactly what happened to my hitch. The main hitch tube, on the exterior facing plane, on the driver side where I’ll see it every day, has some gouges on it that go through the powder-coating to bare metal. I can - and will - paint them to prevent rust (and, therefore, have to paint the whole hitch to match). But the gouges will still be noticeable as they go through the thicker, pebbly, powder-coat finish and will undoubtedly still appear as depressions in the surface even once painted. I fully realize this kind of surface damage will almost certainly happen with regular usage of the hitch anyway and that it’s certifiable to demand absolute perfection in anything. But if you are someone who cares about the aesthetics of your equipment and keeping it looking new for as long as possible, it is very disappointing to receive such an expensive and prominent piece of hardware damaged right out of the box and requiring immediate repainting. The plastic parts bag had also ripped open in transit, with nuts, bolts, shims, etc. rattling around in the box. I am dumbfounded that Curt packages such a high-quality piece of equipment so shoddily where such damage is virtually unavoidable. I bought from Curt solely due to their being an American manufacturer and to support American workers so this is doubly discouraging. It’s a trivial complaint in the big scheme of things and not worth demanding a replacement over. Just be aware that unless Curt changes their packaging practices it is very possible you will have the wind taken out of your towing project sails just as I have. Again, this in no way reflects on etrailer. My experience to date with etrailer (website, educational resources, staff reviews, ordering, tracking, email contact, etc.) has been beyond exemplary in every way. They rank as a Top Five online retailer in my opinion, maybe even the best.


Ordered the whole trailer hitch package but did not include the pin for the ball mount. CHEAP and will never order from you again


Hitch ball and mounts all ready to the test!!!
Five Star e-trailer team, very informative, fast and accurate shipping, perfect packaging and "GREAT" customer service"


2024 CRV.
Pretty straightforward install.
The fish wires in the kit are a fantastic solution to holding the bolts.


I used this on a 2014 Ford Fusion with a Reese receiver hitch made for my vehicle. Either the neck of the drop hitch is not long enough to get the ball a few inches away from the vehicle or the Reese receiver hitch sits too far under the vehicle.


Does the job, however there's a lot of play when hitch mount is inserted into the hitch and when towing with an empty trailer. Very loud. Have to buy a silencer that goes around and secures the product.


I cannot emphasize enough how kind and thorough etrailer's customer experience team is. I originally (incorrectly) place an order for trailer parts that did not fit together, and etrailer took the time to review my order, identify the issue, call and email me to let me know, and place the correct order while over the phone. I am not an expert on any of these items so it is so unbelievably appreciated that they cared enough to check to see if I meant to order what I did. The delivery then arrive a day earlier than expected. What more could you possibly want from a customer service team? Thank you so much, etrailer!




e trailer is my “go to” place for everything i need for towing my trailers
great products - excellent selection - quick delivery and excellent customer service .


My OEM Tow Hitch receiver was rusted out and the Ball mount was rusted to it, I had to replace both and the install went smooth. After I installed the Curt Tow Hitch Receiver I slid in the Curt Ball Mount and secured it with the included pin and cotter pin and I was off to the harbor to Launch my Waverunners for a fun filled day.


The hitch and ball mount are excellent quality. My concerns are twofold. The hitch is so heavy that I had to take it to my mechanic to have it installed. Minor cost and inconvenience, but the hitch for my previous F-150 was just as sturdy, but easy to install myself (albeit with higher ground clearance). My concern about the ball mount is that the factory told me erroneously that it could not be reversed for a drop, so I returned it. This order is for the replacement after I was finally correctly told it could be reversed and how to do that. Ball mount would have been a 3 for that reason, and overall hitch and ball mount quality a 5. So I averaged them.

  • What Hitch Ball Does Curt 3 Ball Mount Use and How Much Does Ball Mount Weigh?
    The Curt Heavy Duty Forged Ball Mount for 3" Hitches # C45432 weighs 27.85 lbs according to Curt. In regards to the platform, I spoke with a representative of Curt who told me it was 1" thick; in addition, the diameter of the hitch ball hole is 1-1/4". For a 2-5/16" hitch ball with a 20,000 lb capacity the Curt # C40008, which has a 2-3/4" long and 1-1/4" diameter shank, would work, or if you need a 2" hitch ball the Curt # A-90 has a 10,000 lb capacity with a 2-5/8" long.
