Video Transcript for Curt Forged Ball Mount Review

How's it going everybody Clayton here at etrailer.com. 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..

Awesome heavy duty ball mount. Used it about 15 times before it was stolen off the back of my truck. Indestructible and great value for the $$.




by:

Product was exactly as pictured and described. Having just purchased a 2019 F-350 dually that did not have the 3” hitch. I’ll be using this hitch to pull a utility trailer from Utah to New Mexico to retrieve some personal items.

Has 1/8 inch of play side to side and up and down

I have a solution for you to help minimize movement in the receiver. I would recommend part number # BLU85QR
Blue Ox Hitch Receiver Immobilizer for 3" Hitches
$60.34
. It will help to eliminate the rattle and sway within your receiver.

Review from a similar Forged Ball Mount in Trailer Hitch Ball Mount


I tried twice to get this hitch and ball from [online vendor]. Twice the shipment was lost and I had to get a refund. Shipment from etrailer is right the first time and arrived quickly. Plus, since the ball is already torqued on the ball mount, I don't need to by a large socket.

Review from a similar Forged Ball Mount in Trailer Hitch Ball Mount


I t looks like an excellent product but I will have to return it (no fault of yours) because it is not the right hitch for my trailer and I have no other use for it. The person who sold me the trailer gave me the equipment that works for it so I am returning your product.

Review from a similar Forged Ball Mount in Trailer Hitch Ball Mount


Arrived sooner than expected. A very sturdy hitch with pin. I especially appreciate having the rounded edges where we frequently walk at the back of the SUV. 4" drop is correct to match my truck and trailer hitch height on my Subaru Ascent.

Still working great

Review from a similar Forged Ball Mount in Trailer Hitch Ball Mount


We’ve already installed it and hitched up the horse trailer. Works great for my needs. Half the weight of the much heavier weight distribution system we had been using (and will continue to use for Interstate travel). Hook up was fast and easy.

  • Does Tongue Weight Sag Get Factored In When Picking Out Rise/Drop Ball Mount
    This is a really great question! So ideally you have the trailer sitting as level as possible when you are towing. So that means that if your vehicle suspension is going to sag with the tongue weight of your trailer on the ball mount you'd want to compensate for that with the amount of rise/drop ball mount you select. How this normally works out is that you determine the drop needed (in your case 8 inches) and then go with a ball mount slightly higher like the Curt part # C45100 which...

  • Adjustable Ball Mount for 3 Inch Hitch on 2018 Ram 2500
    We do have adjustable ball mounts that fit the 3" hitch on your 2018 Ram 2500 but there is not an option for an adjustable ball mount from Curt at this time; instead I strongly recommend checking out the B&W Tow & Stow 2-Ball Mount # BWTS30040B. The Tow & Stow will fit your 3" hitch and will give you a maximum drop of 7-1/2" and maximum rise of 7". It comes with a 2" hitch ball that has a maximum capacity of 7,500 lbs and a 2-5/16" hitch ball with a maximum capacity of 21,000 lbs. The...
