Features to know about
Keeps Your Trailer Level: 2" Rise or 4" Drop
Getting the right height match between your hitch and trailer makes a big difference in how it tows. This Curt Class III ball mount gives you a 2" rise or 4" drop, helping you dial in that level connection that prevents sway and uneven load handling. The 8-1/4" long shank slides into a 2" x 2" receiver, centering the load for balanced towing every time.
Built for Everyday Strength: 7,500 lbs GTW, 750 lbs Tongue Weight
Whether it’s a camper, boat, or utility trailer, you need a mount that won’t flinch under load. Rated for 7,500 lbs gross towing weight and 750 lbs tongue weight, this setup gives you dependable pulling strength for mid-size hauls. The solid steel shank keeps its shape under pressure, and the fixed design keeps your trailer tracking straight without any adjustment points to loosen up over time.
Ready to Tow Out of the Box: Pre-Torqued Hitch Ball Included
No need to hunt down extra hardware—this kit comes ready to go. The 2-5/16" chrome-plated hitch ball is already torqued to factory specs, and Curt includes the pin and clip so you can slide it in, secure it, and get hauling. It’s straightforward gear that’s built to just work without extra setup steps.
Resists Rust and Road Grime: Chrome Ball and Black Powder Coat
Hitch gear lives a tough life out in the elements, but this mount holds up strong. The chrome plating on the ball fights corrosion from rain and road salt, while the black powder coat on the shank adds another layer of rust protection. Season after season, it stays looking clean and working reliably no matter what you drag through.

This was purchased for towing a 7k GTWR utility/landscape trailer with my 2018 Chevy Silverado 1500 WT 4x4.
I measured for necessary drop before ordering, and the 4" drop is darn near perfect.
It's a great help that the 2-5/16" ball comes complete, installed and torqued properly at the factory.
Appears to be quality construction, fits and functions perfectly.
I have no complaints or issues.

Excellent---- Web site is easy to navigate & has informative pages.
Prices continue to beat my local trailer sales.

Parts are packaged well & have always shown up in excellent condition.

Have not used it to tow yet, but Lori B was really helpful confirming dimensions, etc. I have a 2021 Range Rover Sport, and it doesn't leave a lot of room for error with spacing etc., with my 7,000# tandem axle boat trailer. Very pleased that I received exactly what I was expecting, and fit perfectly. Fingers crossed that everything goes well when I actually hitch it up to pull my rig!

Etrailer did a terrific job with my order of a Curt 2 5/16 ball and ball mount. Their pricing on this item was less than half of what Lowe's charged for a similar product. The ball and mount arrived without the pin and clip, but the staff responded immediately and shipped the missing items on the next day. I would definitely do business with etrailer again!

I have never had a bad experience with etrailer.com, we're a large environmental company and 75% of my purchases are with etrailer.com. It's not that I want to go other places, but we do everything to or trailers here from paint to door skins. Not everything is offered here, but if you want great service, after sales service and no nonsense purchasing, I highly recommend etrailer.com.

The product we purchased, a Curt Ball Mount, is exactly what we wanted. It was well packaged and in perfect shape. We would order again from ETrailer.com without hesitation. While they did upgrade my shipping for free it still took the same amount of time as regular shipping but through no fault of ETrailer.com. It just happened that we ordered and the shipping occurred over the weekend. Again, fast, courteous service. I highly recommend ETrailer.com.

See what our Experts say about this CURT Trailer Hitch Ball Mount
- Which Hitch Is Best for Carrying E-Bikes and Light Towing with a 2021 Jeep Cherokee?Hello Sadie, Thanks for writing in. For your 2021 Jeep Cherokee, I'd recommend going with a Class III hitch with a 2" receiver since you're planning to carry two e-bikes and may eventually tow a small boat trailer or lightweight camper. My top recommendation would be the etrailer hitch # e73ZR. Another great option is the Curt hitch # C13395. The two hitches are very similar in capacity and fit, and both will work great for carrying e-bikes or handling light towing duties. The main difference...
view full answer... - Can The Curt Ball Mount C45042 Be Used In The Rise Position?Hello Mel, thanks for reaching out. The Curt Ball Mount # C45042 does come with the ball pre-torqued in the drop position. You can remove the ball and flip it over to use it in the rise position, but you would need a torque wrench and a 1" lock nut in order to do this. Since it comes pre-torqued this one is generally only used in the drop position. If you want something not pre-torqued, use the # C45270 ball mount and the # 40038 ball.
view full answer... - Measuring for Correct Ball Mount on 2017 Chevy ColoradoBased on your measurements you are looking for a 4-1/4 or 4 inch drop for your ball mount. I've attached an article to assist. If you want a fixed mount ball mount, I recommend the4 Curt Class III Ball Mount with 2" Ball - 4" Drop - 7,500 lbs # C45056 if your trailer has a 2 inch ball coupler. If the coupler fits a 2-5/16 inch ball, then I recommend # C45042 instead. These will work well for towing 7,500 lbs with a 750 lbs tongue weight. Anything beyond that should use a weight distribution...
view full answer... - Options for a 2 Inch Ball Mount that Comes with a 2-5/16 Inch BallThe ball mounts that have a ball welded on are all either 2 inch or 1-7/8 inch diameter balls. We have some ball mounts that come with a 2-5/16 inch ball bolted on: # C45331 # C45332 # C45041 # C45042
view full answer... - Towing Capacity and Parts Needed To Tow with a 2016 Ford EscapeThe trailer hitch I recommend for a 2016 Ford Escape is the etrailer Trailer Hitch Receiver part # e98866. This hitch has a bolt-on fit with no cutting or drilling required. It will also work with the hands free liftgate feature if equipped. This hitch has the larger 2" receiver which I recommend due to the greater variety of accessories. In order to complete your setup you'll also need a trailer wiring harness for which I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole...
view full answer... - Ball Mount with 2 Inch Rise and Ball Already Installed in Rise PositionThe Curt ball mount # C45042 only comes with the ball torqued into the drop position but we do have part # C45155. This has the ball in the rise position and it's a 2-1/4 inch rise but it's only a 2 inch ball not a 2-5/16 inch. If you need a 2-5/16 inch ball you'll need to move the ball on part # C45042.
view full answer... - Hitch Ball with 2 inch Rise that has 2-5/16 inch Hitch Ball Installed on ItCurt has a ball mount with a 2 inch rise that fits a 2 inch hitch that has a 2-5/16 inch hitch ball that comes with it with the part # C45042 but the ball is installed in the drop position. You'd have to remove the ball and reinstall it in the rise position.
view full answer... - Best 2 3/8 Ball Hitch RecommandationThe standard sizes of balls that are available are going to be 1 7/8" , 2" and 2 5/16". We do not carry or have I ever seen a 2 3/8" ball. I would remeasure since there is only a 1/16" difference between 2 5/16" and 2 3/8" it might just be a mistaken identity. If you do discover it is a 2 5/16" ball the one you looked at Buyers Products Tri-Ball Hitch part # 3371802200 is a good choice if your trailer tongue when sitting level is even with your receiver tube opening. If it is lower you'll...
view full answer... - Recommended Curt Ball Mount without Hitch Ball with 4 Inch Drop and 7,500 Pound CapacityThe Curt Class III Ball Mount # C45042 referenced in your question includes a pre-torqued 2-5/16 inch hitch ball. This exact ball mount is not available from the manufacturer without the hitch ball, but I do have an option that should work well. I recommend taking a look at the Curt Ball Mount # C45154. This 2 inch ball mount features a drop of 3-3/4 inches or a rise of 2-1/2 inches. It features the same 7,500 pound towing capacity as the Curt unit you were looking at but also has a nice...
view full answer... - Curt Ball Mount and Hitch Receiver Lock Yes, I can confirm that all of those parts do fit together. The Coupler Pin - 5/16" x 2-1/2" item # 37201051 will be loose inside that ball mount though. You will get quite a bit of play. The hole in the Curt Class III Ball Mount with 2-5/16" Ball - 2" Rise or 4" Drop - 7,500 lbs item # C45042 accepts a 5/8" pin. I recommend purchasing a Curt Trailer Hitch Receiver Lock - 2" Hitches - Chrome item # C72KR. This will secure your ball mount inside your hitches receiver and keep it from being...
view full answer... - Recommended Ball Mount with 4 Inch Drop and 10,000 Pound Towing Capacity The Curt Class III Ball Mount with 2-5/16 Inch Ball # C45042 referenced in your question has a maximum towing capacity of 7,500 pounds. For a ball mount that will provide the same 4 inch drop and give you a 10,000 pound capacity, I recommend the Draw-Tite # 40202. This sturdy steel ball mount is compatible with 2 inch hitch receivers and also features a tongue weight of 1,000 pounds. You will just need to add a compatible 2-5/16 inch hitch ball like # 19286. I have attached a short...
view full answer... - Is Hitch Ball Included with Curt Class III Ball Mount # C45042The Curt Class III Ball Mount # C45042 referenced in your question does indeed include the 2-5/16 inch hitch ball that is actually pre-torqued to the platform. The ball mount and hitch ball have a gross towing capacity of 7,500 pounds and a drop of 4 inches. I have attached a short video demonstration on this product that you can also check out.
view full answer... - Recommended Locking Hitch Pin to use with the Curt Class III Ball Mount # C45042If you are just looking for a locking hitch pin to use with the Curt Class III Ball Mount # C45042 then I recommend going with the Trailer Hitch Receiver Lock # e98880. I do recommend using a locking hitch pin that has an anti-rattle feature as well. The Let's Go Aero Lock # 63232 will work with the Curt ball mount and will provide a lock as well as a part of the hitch pin that will help to keep the ball mount from rattling inside your hitch receiver.
view full answer... - What is the Drop Measurement on Curt Ball Mount C45042Curt ball mount # C45042 measures 4 inches from the top of the shank to the top of the ball mount platform. I have linked a video review of this ball mount for you.
