Features to know about

Built for Heavy Loads: 20,000 lbs GTW Capacity

When you’re pulling a full-size camper, livestock trailer, or heavy equipment hauler, you need a mount that won’t flinch under pressure. This forged steel ball mount is rated for 20,000 lbs gross towing weight and 2,000 lbs tongue weight. It delivers solid, one-piece strength you can count on for serious towing jobs, without needing any extra parts or adjustments.

Keeps Your Trailer Level: 2" Drop for Balanced Towing

Uneven trailers can cause sway or uneven wear. This mount gives you a precise 2" drop to keep your trailer sitting level behind your truck. The result is smoother tracking and more stable handling with every load. Its fixed design keeps things simple and dependable—just slide it in, secure it with a pin or lock, and go.

Ready to Tow Right Out of the Box: Pre-Torqued 2-5/16" Ball

No need to mount or torque your own hitch ball. This setup comes pre-fitted with a 2-5/16" chrome-plated ball that’s torqued to factory specs and ready to use immediately. That means less time in the garage and more time on the road. It’s a straightforward setup that takes the guesswork out of towing prep.

Stays Looking Good: Carbide Black Powder Coat Finish

Rain, salt, and road grime can take their toll on towing gear. The solid steel shank is protected with a corrosion-resistant carbide black powder coat that stands up to rust, chipping, and UV damage. Paired with the chrome-plated ball, this finish keeps your setup looking sharp and working reliably season after season.

Secures with Confidence: Works Great with Locking Hitch Pin

Once mounted in your 2-1/2" receiver, this ball mount pairs perfectly with a locking pin like the etrailer Hitch Receiver Lock # e98881 (sold separately). It’s an easy way to add peace of mind when you leave your setup on the vehicle, keeping everything locked tight and ready whenever you need to tow.

For years ive had the 2 inch version and it has been the best hitch ive ever used. My new truck came with a 2 1/2 receiver so i upgraded instead of using the adapter and i am pleased so far. Exactly what i had expected, great product.



by:

Quality product. Excellent service



by:

Holy cow! This thing is heavy duty.
Which
it should be, because it ain’t cheap! If you’re dragging heavy, you need to remember, it only costs 50% more to go first class!

I might lose a trailer, but, it won’t be because the hitch broke!

by:

We have been extremely satisfied with the purchase of this trailer hitch mount. We have used it for about a year towing a dump trailer, almost every day, and we haven't had any issues with it.



by:

Hitch ball mount looks good and fits in the tube. There is a little wiggle in the tube but doesn’t seem to be enough to cause trouble. I need to invert the mount to get a 1/2” rise but the nut is 7/8” flat to flat. I don’t have a socket big enough to fit that. So I’m either going to have to buy or borrow one.



by:

Curt products are great. Built like a brick s*** house. I won’t even consider any other brand. I’ve used them for decades and have zero issues with them. Got a new truck that has a 2 1/2 hitch so I had to get a bigger set.

See what our Experts say about this CURT Trailer Hitch Ball Mount

  • Hitch Pin Recommendation for Curt Heavy Duty Forged Ball Mount for 2-1/2" Trailer Hitch Receivers
    I recommend securing the Curt Heavy Duty Forged Ball Mount # C83JR to the 2-1/2" hitch receiver on your truck with a locking pin as it adds more peace of mind to your towing setup. The etrailer Hitch Receiver Lock # e98881 is a great solution for this as it's easy to use and it does a great job at resisting rust and corrosion. I actually have a friend who left this on her vehicle for a few years and she said it still works good as new even after being exposed to all sorts of weather.

  • Anti-Rattle Recommendation for Curt Heavy Duty Forged Ball Mount for 2-1/2" Hitches
    I recommend using the Roadmaster Quiet Hitch # RM-062 to keep the Curt Heavy Duty Forged Ball Mount for 2-1/2" Hitches # C83JR stable in the hitch receiver. The Quiet Hitch essentially clamps the ball mount to the hitch receiver so there isn't any tolerances for the ball mount to move around in. It's a pretty simple device but it's also very effective. Attached is a review video for you to check out!

  • Hitch Receiver for 2016 Chevy 2500HD
    Thanks for letting us help Jade. Yes, the Curt Trailer Hitch Receiver # C15860 will fit for your 2016 Chevy Silverado 2500HD. This heavy-duty Class 5 hitch features a 2-1/2" receiver and is rated for up to 20,000 lbs of gross trailer weight and 2,700 lbs of tongue weight. For an equally heavy-duty ball mount, you could pair it with the Curt Heavy-Duty Forged Ball Mount for 2-1/2" Hitches with 2-5/16" Ball # C83JR. One important thing to keep in mind is that installing a higher capacity...

  • Can Curt Heavy Duty Forged Ball Mount # C83JR Be Used in Rise Position
    Hey Greg, so the Curt heavy duty ball mount part # C83JR that you referenced can be used in the rise position but we don't offer a way to flip it's orientation before shipping it. You would have to flip it once it arrives to you. At that point it would have a rise of about 1/2 inch or so. What are you towing?

  • Hitch Pin Recommendation to Use with the Curt # C83JR
    For the perfect locking hitch pin with the Curt Heavy Duty Forged Ball # C83JR, I recommend the etrailer Hitch Receiver Lock # e98881. This lock is made specifically for 2-1/2" hitches and accessories. If you need a bag to hold your ball mount and lock when not in use, I suggest the etrailer Accessories Bag # e98900.

  • 2-1/2" Adjustable Channel Shank Without a Hitch Ball
    Hey Rick. I have the perfect thing for you. The Curt Replacement Shank # C45917 is the 2-1/2" hitch size you're looking for with the channel design for adjustable rise and drop. This comes with no ball, so you don't have to add another to your collection. The interior channel is 3" wide, so you'll need a ball mount or ball this size to fit in the channel. The pin holes for securing your own ball to the shank is 5/8" in diameter, so you will need pins this size to hold a ball in. Sounds...
