Video Transcript for Curt Hitch Ball - Trailer Hitch Ball - C40007 Review

Today we're going to be taking a look at part number C40007. This is the Curt Chrome Hitch Ball with 2 5/16ths inch diameter, steel construction with a chrome finish, so it's going to offer protection from rust and corrosion. It's also going to feature the wrench flats here on the side of the platform. It's going to allow you to easily get your wrench on there and tighten to the mount and you can easily get it torqued to specifications listed by the manufacturer. The torque rating for this particular mount is indicated in the instructional tag here on the backside. It says that it needs to be tightened to 250 foot pounds of torque. The capacity on the ball is going to be 10,000 pounds.

The shank diameter, this portion here, is going to measure 1 inch. The shank length, measuring from the bottom of that platform to the end of the threaded portion, that's going to give us a measurement of 2 1/4 of an inch. It does include the lock washer, as well as the nut. That's going to do it for today's review of part number C40007. This is the Curt 2 5/16th inch Chrome Hitch Ball, rated at 10,000 pounds. .

Durable steel ball has a 1" diameter x 2-1/4" long shank. Built-in wrench flats ease installation. Chrome finish resists corrosion. Fine threads provide strong grip. Lock washer and nut included.


Fit the Brophy class IV 10” drop hitch I ordered with it perfectly.


Paula and etrailer are great! I needed a higher rise hitch and Paula was great to help me return the one I purchased and get the right one ordered!!!! Thank you!!!


Landed on my doorstep less than 72 hours late w free shipping. Can't ask for much more and the Curt 2 5/16" ball replaces a 15 y/o ball so I'm good for another 15+. Can't go wrong with either Curt or etrailer. Thx again.


This trailer ball is well made, the threads are cut nicely, and it fits the trailer hitch tightly. I gave it 4 start out of 5 because it does not have a terribly heavy trailer rating considering it is a 2 5/16 ball. I understood this when I ordered it, as my trailer isn't that big, and I needed a ball with a 1 inch shank. I received very good help from the salesperson on the phone, in getting my order together. All in all a good experience.
PS Quality wise, for a 10,000# ball, this should probably be 5 start, but I gave it 4 stars because most 2 5/16 hitches are rated for far more than that, and for a bigger trailer, I wouldn't want the ball to be the weak link.

Working great

Excellent product. Great company to do business with.


The ball, ball mount and pin and clip all function nicely. The Brake controller along with the wiring harness were very easy to install. Controller applies trailer brakes smoother and more effectively than any I've ever had. Order process was easy and shipping was prompt. Very Satisfied.


Used it with maxx tow adjustable height ball mount hitch also ordered from etrailer. It worked well with no issues. Came in very handy when needed. Free shipping was a big plus.


quality ball


Needed a 12" drop hitch for my truck since it has quite a bit of lift. Not only did etrailer have the highest rated 12" drop hitch I could find but also the cheapest! I also ordered a 2 & 5/16ths ball that also rated at 10,000lbs. My boat and trailer loaded up is about 6500/7000 so this will def cover the pay load and then some. Shipping was very fast and everything was well boxed together. Would def recommend this company to anyone I knew.


I purchased these items one week before a Thanksgiving camping trip. I recently bought a new camper and forgot that I needed a 2 and 5/16 ball with a hitch that supports my trailer sway system. I picked 5 to 7 day shipping (foolish) and was pleased when my order was upgraded to 3 to 5 day express shipping FREE. Everything arrived 3 days before our trip and worked perfectly.

Great products and great customer service. Happy Thanksgiving to all ...


Used for over a year and product is great. No concerns.


Received my 12" drop and ball about two weeks ago, the shipping was phenomenal ! They got it to me in two days on standard shipping. The drop works great with my 8" lift on my f250. Town straight as a arrow, and the cushion mount Smith's out any trailer slam I have felt with in the past.


All of the products are High quality, what I expected them to be. But even better, they came with-in a 24 hour period, and that was the best part of it all, because I was not expecting the parts to arrive until at least 5 days. As I said on my earlier review, I had searched around my town where I live, and could not find an inexpensive towing ball in the size that I needed for the right price, nor the friction sway control kit, and one could just forget about finding a sway control bracket. Thanks, again etrailer for such great service, which I truly thought, didn't exist anymore.


I needed a 2 5/8" hitch ball with a 1" shank to fit my truck and trailer. None of the local stores carried this combination. Your store had just what I wanted and the price with shipping was no more than picking one up in the store. Your on line order process was simple and I had my equipment in just a few days! I will shop here again if I have a need.


The Curt chrome Hitch Ball 2-5/16 - 10,000 pounds with a 1 inch shaft fits perfectly in my current 10,000 pound receiver. I am towing a 8,500 pound load with an Atwood Coupler. The coupler and ball fit each other without any problems.


This is actually the second order I have placed and normally I don't do surveys or reviews but the quality of the parts is outstanding and both orders were delivered with in in three days. I am a first time trailer owner and picked up my trailer yesterday all of the parts fit perfect and look great. The thing I really appreciate are the step by step installation videos.


Installed easily, worked well with an adapter on an equalizer hitch


Perfect. Correct hitch ball for my horse trailer thanks to these guys. Thanks for making me feel I am towing my precious cargo as safely as possible.


What can I say. A ball is a ball. It was fine.

Still fine.
Peter - 09/28/2021


One of the few hitch balls rated at 10,000lbs... and my new trailer weighs in at 9600. Mounted cleanly. We'll find out how it works when we pick up the trailer on Saturday.


I purchased this ball to go with the AMSC 12 cushioned ball mount I purchased at the same time. I was tipped by other reviewers that this ball had a 1# shank and would be difficult to purchase elsewhere being a 2 5/16# ball rated at 10,000 lbs. I won't be using it for another month or so but glad I have it on hand so it will be there when I need it. Thanks to your other reviewer for this info


Used it to tow an empty 2500lb utility trailer with my Subaru Outback from CO springs to New Mexico. Worked great on the 380 mile trip, no problems, very heavy duty construction.


I received my order very quick and all items are just as advertised. I will defantly order from e-trailer again. Prices are ok too. I am impressed with the product lines they offer.
I'll be in the market for one or two trailer brake controllers very soon.


Using to move a dump trailer with my tractor to move firewood. Needed long enough shaft for a 1 1/4 drawbar. Works well for my application.


I ordered a ball mount and 2 -2 5/16 in balls. they were exactly
what I ordered and were shipped promptly. very happy with both
the product and service.
