Video Transcript for Comprehensive Review: 2-5/16" Hitch Ball-C40005

What's up, everybody It's AJ with etrailer.com. Today we're gonna be checking out this CURT hitch ball. We're gonna be putting it on our ball mount right here. It's gonna be a two and 5/16-inch size. Let's check it out. Hitch ball is gonna be an important part of your ball mount, so you're gonna make sure you get the right size for the coupler on your trailer, because it's what your trailer's gonna sit on.

So this is two and 5/16. And then the shank here is gonna be an inch diameter. So make sure that matches up with the ball mount you want to use. We'll drop that through. We got a lock nut and a regular nut that we'll put on there underneath.

Now I'm just gonna hand tighten it today. You're gonna want to make sure you torque it down to the right specifications when you get it. You can't just tow with a loose ball on the ball mount. So as you're tightening it down, you can see the flat sides on this, the base here of the ball. That's gonna be good for the wrench to get in there and hold that tight, so you can really tighten down the bottom to make sure it's torched.

This two and 5/16 hitch ball has a gross trailer weight rating of 7,500 pounds. It's gonna have a tongue weight rating of 750 pounds. So just keep that in mind with what you wanna haul. You want to go with the lowest common denominator in your setup. So the ball's rated at 7,500 gross trailer weight rating.

Your ball mount here is only rated at 6,000, and the hitch might be less than that. So whatever the smallest number is, go with that one, so you don't stress out your setup. The ball is gonna have a chrome-plated nickel finish on it. It's gonna hold up to the elements. If you leave it on the back of your vehicle all the time, it won't rust and corrode. Also, when you go to hook up to your coupler, it will scratch it up a little bit. That just comes with towing a trailer. That was a quick look at this two and 5/16-inch ball from CURT. Now just make sure you get those measurements on the ball mount you want to use it with, that shank being an inch diameter, and making sure your trailer is a coupler with a two and 5/16-inch ball that will work with it. I think that does it. Thanks for hanging out and hope this helped.

Met all expectations. I wish it was packaged better with my other items. The ball was loose in the box and was smashing into my new chromed draw bar during shipping. The wrench flats were helpful installing this into the draw bar.



by:

Looks like a good quality tow ball. I'll never be able to tell you though. I cut the shank off to build my own trailer coupler lock for cheaper than a purpose built coupler lock. This ball plus the e98883 coupler pin lock makes my trailers secure in my yard as well as anywhere we go. Trailer can't be towed away if there is already a hitch ball locked in the coupler and there a only enough shank left to grab the ball but not enough left to hook it to a new hitch reciever. And by buying enough keyed-alike coupler pin locks, one key fits all trailers unlike previous setups I tried where each coupler lock had its own key.

  • Recommended Weight Distribution Hitch For V-Nose Trailer
    Thank you for providing that picture and measurement. Based on what you have there there is definitely enough room to install a weight distribution hitch. I recommend the Fastway e2 which will require placing the brackets 27-30" back along the frame, leaving you with room to spare. The correct system will depend on the tongue weight of your loaded setup. The best way to find this is to measure with a scale like the # e99044. I have also attached an article below which covers other ways...

  • Recommended Weight Distribution Hitch for Somerset E3 Pop Up Camper
    That answer you looked at is a bit confusing and I think it gave you the wrong idea about weight distribution. A weight distribution hitch should not be selected based on your tow vehicle. The most important thing is making sure your loaded tongue weight falls into the tongue weight range of the hitch. I don't know what year or exact model you have but I'm guessing 268 lbs is the dry tongue weight. You will need to measure to see what your loaded tongue weight is, or at least find the...

  • Recommended Weight Distribution Hitch for 2019 Toyota Highlander Towing 2018 R-Pod 179
    The weight distribution hitch in the question you looked at was based on the loaded trailer tongue weight. It is impossible to find the right WDH based on the vehicle alone. It looks like your 2018 R-Pod 179 has a dry tongue weight of 292 lbs so based on the GVWR you're probably maxing out tongue weight around 400 lbs. To be sure, I recommend measuring your fully loaded tongue weight setup with a scale like the # e99044. Based on that information, the Fastway e2 # FA94-00-0600 would not...

  • Recommended Weight Distribution Hitch For A Jayco Jay Flight SLX 174BHW
    Hi Bill, The Fastway e2 Weight Distribution w/ 2-Point Sway Control # FA92-00-0450 has a tongue weight range of 200lbs - 450lbs so you'd be right around the middle of the capacity when loaded, making this a great choice. This doesn't come with a hitch ball so you'll need either a 2" ball # 40038 or 2-5/16" hitch ball # C40005 depending on your coupler size. I've attached a short video below where we'll show you how this system works.

  • Trailer Hitch Ball Sizes Commonly Used With a Class III Receiver
    While most your class 3 trailer hitch receivers are rated for 3,500lbs-8,000lbs the hitch ball size is generally determined on the trailer. The 1-7/8" Hitch Ball # 19260 is generally found on very small trailers with a total weight below 2,000lbs. The 2" Hitch Ball # 40038 will be the most common size used on most utility trailers you would be able to tow. The 2-5/16" Hitch Ball # C40005 is commonly found on larger trailers but is also the most popular size used on camping trailers. We...

  • Recommended Ball Mount To Replace Curt C45901 With Missing Parts
    I reached out to my contact at Curt and while I have a complete replacement option for you, the ball mount section of the # C45901 is not available separately. Since there is no other ball mount option of the same style that will fit your shank, you will need to purchase another # C45901. In addition you will need a hitch ball with a 1" shank, the 1-7/8" # C40002, 2" # 40083, or 2-5/16" # C40005. I included a video of the # C45901 for you to take a look at.

  • Will Brophy Ball Mount BM20 Allow Rear Hatch to Open
    Yes, the rear hatch on your Ford Explorer will still be able to open when using the Brophy Ball Mount for 2" Hitches # BM20. You wouldn't need sway bars due to the longer ball mount so you're set there. You'd only need a hitch ball, either 2" hitch ball # C54CR or 2-5/16" hitch ball # C40005 depending on your trailer coupler. Then to secure the ball mount use pin and clip # C21504 or hitch lock # e98881.

  • Recommended Weight Distribution Hitch For A 2017 K-Z Sportsmen Classic 14RBT Travel Trailer
    To get the best performance out a weight distribution hitch you'll want to first know your trailer's fully loaded tongue weight. Once you're fully loaded you could use a tongue weight scale like the # e99044 to get an accurate number to work with. Most likely you'll fall around the 400lb range. If you're experiencing a minor amount of sway then I recommend the Fastway e2 Weight Distribution w/ 2-Point Sway Control # FA92-00-0450. This system has two friction points (where the frame brackets...

  • Sway Control For Hitch Not Rated For Use With Weight Distribution
    Good question, and the hitch on your Audi is not rated for use with weight distribution, so what I recommend instead is a friction sway control set up. This will provide you with better control over your trailer to give you a much more controlled, steady, and comfortable towing experience. The way it works is the ball plate from the kit attaches to your trailer frame, and the other end attaches to a tab on a ball mount, like in the accompanying photo. Just keep in mind this will only...

  • Best Trailer Hitch Receiver and Wiring Kit For a 2022 BMW X3 M40i
    I recommend the Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit # SH62VR as being the best receiver for your 2022 BMW X3 M40i. When not needed the ball mount or receiver tube can be removed so you will not see a receiver on your BMW. The wiring is also included for a 7-way trailer connection and a 7-way to 4-way adapter is included that fits smaller trailers. The included ball mount comes with a 2" ball. You can change it out with a 1-7/8" Ball # C40002 or 2-5/16" Ball # C40005...

    Good questions, and as far as the weight, I checked with the manufacturer and the total weight is 73 lbs for the Steadi-Flex you asked about, which is the following part number: - Reese Steadi-Flex Weight Distribution System w/ Sway Control # RP66558 The Steadi-Flex # RP66558 does not count as tongue weight as it is essentially part of the hitch, but it does count against total payload, which you'll want to keep in mind.

  • Trailer Surge Brake Actuator Option For 3-1/2 Inch Wide Trailer Frame
    Almost all trailer brake actuators are designed for 3 inch wide trailer frames, the only option would be to weld a coupler on top of your 3-1/2 inch frame. The issue with this for you is that the options for those only accept a 2-5/16 inch hitch ball, so if it all possible you would need to switch to that, with either the 1 inch diameter shank 2-5/16" Hitch Ball # C40005 or 1-1/4 inch diameter shank 2-5/16" Hitch Ball # C40030.

    The Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit # SH27FRT along with all other receivers for your 2017 Volvo XC90 are not able to be used with a weight distribution hitch system. You will most likely need a 2-5/16" Hitch Ball # C40005 to replace the 2" ball included with the receiver. Or you can get a 2nd Ball Mount # 391BMU5S if you will be towing multiple trailers.

  • Recommendation For Reducing Rear Sag On a 2022 Toyota Highlander Towing a Pop Up Camper
    I recommend using a Fastway e2 Weight Distribution # FA92-00-0450 as there is not any suspension enhancement available for your 2022 Toyota Highlander XLE. The Fastway e2 will not only help to reduce rear end sag but it will also add trailer sway prevention to make towing safer. You can use this hitch on trailers weighing up to 4,500lbs and a tongue weight up to 450lbs. You will need either a 2" # 40038 or 2-5/16" # C40005 hitch ball to match your pop up campers coupler.
