Features to know about

Keeps Your Trailers Level: 4-1/2" Drop or 6-3/4" Rise

Leveling your trailer is key to stable, even towing. This adjustable mount gives you a 4-1/2" drop or a 6-3/4" rise so you can fine-tune the height for any trailer you pull. The shank slides smoothly into a 2" x 2" hitch receiver, and the ball platform locks in place with the included pins and clips. Once set, your trailer tracks straight and steady, no matter the load.

Tows Heavy Loads with Confidence: Up to 10,000 lbs GTW

When you’re hauling serious weight, strength matters. The heavy-duty steel build of this mount handles up to 7,500 lbs when using the 2" ball and up to 10,000 lbs when using the 2-5/16" ball. Tongue weight ratings of 750 lbs and 1,000 lbs keep your setup safe within limits. It’s the kind of solid, no-nonsense construction you want when pulling large campers, boats, or equipment trailers.

Simplifies Switching Between Trailers: Built-In 2" and 2-5/16" Balls

If you tow more than one trailer, swapping mounts gets old fast. With two built-in hitch balls—2" and 2-5/16"—you can change coupler sizes in seconds. Just remove the pins, rotate the balls, and reinsert them. The clevis bar adds more versatility by letting you use a lunette ring (sold separately). It’s a quick way to stay ready for whatever you’re towing next.

Built to Last: Corrosion-Resistant Finishes That Hold Up

Road salt, water, and sun take their toll on towing gear. This mount fights back with a black powder coat on the shank and chrome-plated hitch balls that resist rust and wear. Season after season, it keeps its clean look and solid performance without needing extra upkeep.

Ready for the Long Haul: Secure Fit and Reliable Hardware

Every part of this setup is made for stability on the move. Three 5/8" hitch pins keep the adjustable parts locked down tight, while the included hitch pin and clip secure the mount in your receiver. It’s a simple, sturdy design that stays put mile after mile so you can focus on the drive ahead.

Video Transcript for Feature Review Curt Adjustable 2-Ball Mount

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at this Curt Adjustable two ball mount. This is gonna be a more value-oriented ball mount. Certainly not the fanciest thing in the world but it gets the job done and offers a lot of features with it, including a two-inch ball, a 2 and 5/16 ball, and a clevis bar if you have a lunette ring trailer and you need that option on occasion it's gonna be there for you when you need it. Plus you've got all the easy height adjustment that an adjustable ball mount would offer.

Let's check it out. Now, the first thing you'd probably want to know is whether or not the ball mount is up to the task to perform how you need it to. In terms of weight capacities, the 2 inch ball up top has a gross trailer weight rating of 7,500 pounds and then the 2 and 5/16 ball over here that you can flip up to the top that's going to have a 10,000 pound capacity. If you are using the clevis bar with a lunette ring trailer that's also going to have a 10,000 pound capacity. And then the ball mount overall has a 1000 pound tongue weight rating.

That's gonna be the same for whatever ball or clevis bar you end up using. The other thing you wanna keep in mind is the range of adjustment you have with the ball mount. In this position, we've got it in the lowest drop position with the ball, you're gonna get a 4 and a 1/2 inch drop. Now if you're using the lunette ring trailer here, you can get up to an eight inch drop cause it's gonna sit a little bit lower. If we we're to take the entire ball mount out of the hitch, flip it around into the rise position, we can get a much bigger rise out of it up to 6 3/4 of an inch of a rise in that top position.

And then again, for the lunette ring trailer that'll be a little bit different. That'll be a 3 1/2 inch rise. So that's the whole range that you have to work with. Now how you make those adjustments is with the two pins at the back right here. We'll remove the included clips and the pins and the whole assembly here can slide up and down the entire ball mount here.

With these holes that are spaced apart periodically you'll need to pick one and then have the hole right below that also occupied and then secure those again with those included clips. Now for the 2 inch ball up top here, that's also got the clevis bar attached to it. So let's say we don't need the clevis bar and we don't need that 2 inch ball. All of those can get completely removed by taking out this included pin and clip. If you do need one of those things, then you will have to drop it in and secure it over the top with the pin and clip. So if you need the 2 inch ball, you're gonna have a lot more going on here of just extra stuff because you need those two pieces to complete the hold and that ring attachment point. Now let's say you just need the 2 5/16 ball. All of that can go away for now, if we want to have this be a little less bulky and you just go through the same process that we did to adjust the height with those pins and clips and just flip the whole assembly over, pick your height like that and get it secured in. Now personally, this method for switching between the different balls and especially for the clevis bar right here feels a little bit clunky to me. But at the price point, I'm not expecting it to be something that's super smooth and well refined. I think something that maybe works a little better if you are gonna be using a lunette ring trailer is one that it just uses the existing ball on top and then has a bar or a piece that just drops over the top of it to secure it in place. Now the ball mount does stick out quite a bit from the vehicle. From the center of the hitch pin hole to the center of the ball or where our trailer's going to be attaching is going to be 14 1/2 inches. So that's kind of nice though because we do get a good amount of distance between our vehicle and our trailer to maybe help with some turns. And then at the hitch pin there, something to point out is that it's not included with its own hitch pin. All the pins to control the adjustment are included but the hitch pin doesn't come with it. So you will need to pick up your own. I'd maybe recommend the etrailer locking hitch pin. Really anything that locks up will do the trick though. The overall construction here is gonna be a steel construction with a black powder coat finish on top and a chrome plating over the balls themselves. All that will help it resist rust and corrosion over time. But the more you use it, the more that gets chewed up. Maybe the powder coat flakes away. You probably will start to see signs of rust and corrosion but it's nice to know that some of that is there just to help it resist that over time. Now overall, if you're going to be looking at a ball mount and you need it to have all these points of adjustment and the different methods of attaching, including that clevis bar, then I think this is a pretty okay option. At the end of the day though, it is more of a budget friendly choice and it's not the nicest. You can certainly spend a lot more money and get something that's a lot easier to use and maybe a bit stronger, but again it's also a lot more expensive. My recommendation would be if you don't need that clevis bar then just go for an adjustable two ball mount. You can get a lot nicer ones for a similar price that just have those two features and don't offer the clevis bar. My recommendations for that would be another option from Curt, or you can go for one from Bulletproof hitches. I think that Bulletproof Hitches one is going to have a much better build quality. Those are ones that I've had direct hands on with quite a bit, and they make them really well. You might not get the exact same adjustment points in terms of the rise and the drop but you will get better weight capacity with that one, along with that better build quality. And that'll do it for our look at this adjustable two ball mount with the clevis bar from Curt. Thanks for watching.

This hitch is so heavy duty. I like that it has
Two ball sizes. Recently I rented equipment
from Home Depot & it required a 2&5/16 ball.
I just flipped the hitch over and hooked up
by:
I did my research curt is my best option solid shaft 2 in receiver just what I need to pull my 14 K trailer pulls like a dream.
by:
The anti rattle feature makes it very difficult to get the 2nd pin in. I hope that it wears down with time and becomes easier, if not I will be filing it down. I have a different hitch for my 2500 that I love and wish they made with the same rating in a 2" receiver. Still rating it average as I like the 2 ball functionality and height adjustment to fit both of my trailers with this one hitch. I just wish it was easier to adjust.

One later and it has worn in where it is much easier to remove and re-install the 2nd pin. It took a month or so and a handful of adjusting it and it is much smoother and easier. Now my only complaint is that it sticks out a good amount further than any other mount and trailers with shorter chains or wiring may need to be extended. Still satisfied as these are minor complaints and it performs its main function of adjustability for multiple trailers excellently.

by:
Great combo. Extremely heavy duty, and gets the trailer tongue jack out far enough for the tailgate to come down with plenty of clearance.
by:
Great buying experience as in the past. I ordered my hitch on a Sunday evening and it was delivered free to my doorstep on Wednesday.I highly recommend Etrailer for all my truck and trailer needs.

This is a fantastic hitch. I regularly pull a 15K equipment trailer with this hitch. I do keep it well greased and have seen no real signs of wear other than minor rubs on the gold colored treatment on the 2 516 ball. Ive also pulled a 9K trailer over 4,000 miles across country on the 2 ball. The hitch fits well, doesnt make much clunk or rattle noise when unweighted. I have had other hitches that made a lot of noise because the fit was sloppy. Thats not the case with the Curt 2.5. Overall, Im very happy with the hitch.

@Douglas You've perked my curiosity about taking one of your trailers cross country. Was it for a trip?

@GwendolynY Yes, I rented an enclosed trailer to clear antiques from a house after a relative passed away. The trip was from Texas to Washington State and back.

@Douglas I'm sorry for your loss. But I'm glad that you were able to make the trip, and I hope you got to enjoy the scenery on the way.
by:
I have been completely satisfied with this product. Very durable, solid beyond my expectations. Whether towing 1/2 ton or 6 tons I have no concerns that the trailer and load aren't safe and secure. Would purchase again but won't need to as this hitch was built to last.
by:
First of all, ETRAILER is a great company in my opinion. Their selection, prices and customer service are all great.

This hitch is stout! I'm the type that I'd rather have more capability than what I may actually use. For what I will use this for, I'm 100% sure it will be way more than I'll ever need but I'm also confident that I would not have any issues using it regularly at it's maximum capability. The construction of it is top notch and I'd be willing to bet it can do more than what it's rated for.

I will definitely be ordering the 20K Pintle that works with this as well as a Curt 5th Wheel and Gooseneck. Thank you ETRAILER and thank you CURT for amazing service and and amazing product.
by:
Hitch is very heavy duty which is nice. Think some more engineering could go into it so you don’t have to use the Allen to snug hitch to keep from rattling. I ended up purchasing the rubber inserts. Definitely recommend if towing heavy trailers.
by:
I haven't used it yet but it looks to be everything I expected it to be. Very solid piece of equipment that I expect to last a very long time! It's not as fancy as a nice B&W but it doesn't cost as much either!!!

The Curt hitch has done everything that I have needed it to do with no problems. However, I will say that I wish I would have went with a B&W hitch that isnt as heavy and can hide the ball under the truck while leaving the hitch in the truck. I knew what I was buying so it is nothing against the Curt, but it is very heavy and awkward to take on and off and it takes up a lot of room if I put it in the cab of my truck. That being said, I have full trust in the hitch when hauling any and all trailers!

by:
Just to let you know, as a long time user your hitch's are the safest and strongest ever to pull my trailer. I never needed a adjustable hitch but two things happened that changed my mind. A big rain at the race track recently required many trailers to be relocated we needed hitches with various ball heights. Also my jet ski trailer, open boat trailer and my race car trailer all need different height and ball sizes. thanks for making a very good product.
by:
This is a very nice quality hitch and it made leveling the differnt trailers I have very easy. Very satisfied. Thanks for the fast shipping too!
by:
The product is everything they said it was and more, the adjustment capabilities are great along with the ability to extend the receiver. I plan to pull a 26 foot car trailer at about 12,000 pounds loaded. The service and concern as always was excellent. I highly recommend this product and certainly etrailer.
by:
The hitch arrived quickly and as expected. Normally a hitch that weighs as much as this one (37.5lbs shipped) is hard to order online due to the weight of the item but etrailer really made it easy. The interaction with the folks from etrailer was perfect. They were detailed in their email and made every effort to make this a personal experience.
by:
It's great quality and heavy duty. We haven't used it yet, but we look forward to.
by:
Good hitch
No problems
Easy to switch t
o the size I need
by:
A very useful hitch. Easy to adjust and solidly built. Only minor problem is my tail gate step on my GMC Sierra 2500 hits it when the hitch is installed. Great product.
