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..

by:

great quality and about $70 cheaper than my local trailer dealer



by:

Perfect! Exactly what we needed.



by:

Looks well made and very heavy duty. Like the description indicates, forged so no welds. Also, solid shank, not hollow. Only bummer is that it is not made in the USA.



by:

Received ball mount in two days but have not used. I have the exact type with 2" drop - never had problems.

When I called etrailer.com about price matching they was friendly and did as price match policy states.

Always great service!!!!



by:

I was so impressed with the 4” drop mount, that I bought this 6” drop mount for my open trailer. Very heavy duty piece, very dense, and the weight of the unit makes me comfortable that it will be plenty strong.

I purchased Curt's 6" drop ball mount for my 2012 Jeep Wrangler Sport which is not lifted but has 32" tall tires. The utility trailer I plan to purchase recommends a 12" tongue/ball height for level towing. The Curt 6" drop ball mount places my tongue/ball height at 13.5" which is acceptable. The bottom of my tow ball mounting nut is now 12" above the road surface. Plenty of clearance for safe towing. I'm very pleased with the quality and functionality of my Curt ball mount. I'm looking forward to purchasing a utility trailer soon. I think it will tow very nicely using my Curt 6" drop ball hitch.



by:

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.
