Video Transcript for Curt 2-5/16" Chrome Trailer Hitch Ball Review

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.

2-5/16" Hitch Ball - 1" Diameter x 2-1/8" Long Shank - Chrome - 7,500 lbs - C40005

by:

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 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.

  • Can Draw-Tite Ball Mount 2923 Give 3/4 Inch Rise
    Yes you can; flipping the Draw-Tite Ball Mount # 2923 upside down will give you the 3/4" rise you are seeking. It comes with a pin and clip so for a hitch ball you will need - depending on your trailer's coupler - either 1-7/8" Hitch Ball # C40002, 2" Hitch Ball # 40038, or 2-5/16" Hitch Ball # C40005.

  • 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.

  • Extended Ball Mount Options For 2 Inch Hitch For Clearance
    There are a couple options for extended ball mounts that fit 2 inch hitches and have extra length for clearance. You didn't mention the rise or drop you need so I'll give you a couple choices so you can find the right one: - 1" Rise, 2" Drop - 14" Long: Brophy Ball Mount # EA20 - 3" Rise, 4" Drop - 14-5/8" Long: Brophy Ball Mount # EA40 Apart from being extra long, both ball mounts are aluminum so they won't corrode, and have an 8,000 lb towing/800 lb tongue weight rating.

  • What Size Wrench is Needed to Install Hitch Ball # 63840
    When installing the hitch ball part # 63840 you need to use a 2 inch wrench on the wrench flats of the ball and a 1-7/8 inch wrench for the nut on the shank.

  • Shorter Tow Ball for Travel Trailer
    I recommend the Curt 2-5/16" hitch ball item # C40005. It has a 1" diameter x 2-1/8" long shank, with 0" of shank rise, and is rated at 7,500 lbs.

  • Recommended 6 Inch Drop Ball Mount with Extended Length for a 2 Inch Trailer Hitch Receiver
    I recommend using the Curt Ball Mount part # D-28 which has a 6" drop. We do not have a 2" ball mount that offers exactly 6-1/2" of drop with an extended shank but since the vehicle will squat a bit while attached to the trailer, the 1/2" difference will not be an issue for you. This ball mount slides into a 2" receiver tube opening and works with hitch balls that have a 1" diameter shank. If you need a hitch ball I recommend using part # C40002 for 1-7/8", part # C40004 for 2", or part...

  • 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...

  • Can 2” Hitch Ball With 1" Diameter Shank Be Replaced With 2-5/16" Hitch Ball
    As long as you use the same diameter shank you can definitely replace your 2" ball. I recommend the 2-5/16" Hitch Ball - 1" Diameter x 2-1/8" Long Shank - Chrome - 7,500 lbs # C40005. Since this has the same 1" diameter shank you will not have an issue using it with your existing ball mount. This ball has a 7,500 lb capacity and comes with a 1 year warranty.

  • 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...

  • Can Extra Long Hidden Hitch Ball Mount # 80232 Use 2-5/16 inch Hitch Ball
    Yes, you can install a 2-5/16 inch hitch ball on the platform of the Hidden Hitch ball mount part # 80232 that you referenced. You'd just need a ball like the Curt 2-5/16 inch hitch ball part # C40005 which is designed to fit 1 inch diameter ball holes like what that ball mount has.

  • 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...

  • Ball Mount with 2-5/16 inch Hitch Ball to Fit OEM Hitch of 2022 Volvo XC90
    Your 2022 Volvo XC90's factory hitch is basically a standard 2 inch trailer hitch so for a ball mount solution that will allow you to use a 2-5/16 inch hitch ball you'd want the Curt # C45030 and then for a hitch ball the part # 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.

    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. The Autowbrake Electric Brake Controller # 3430001 is going to be the simplest brake controller to use...

    Congrats on your trailer purchase and we can definitely get your 2016 Jeep Cherokee set up for towing it.

First, let me go ahead and start with the basics for your '16 Cherokee, the hitch and wiring harness: - eTrailer Hitch # e73ZR - T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118605 - Universal Installation Kit for Trailer Brake Controller...

  • 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.

    The Equal-i-zer Weight Dist Shank # EQ90-02-4600 is designed to work with a weight distribution hitch head like # EQ90-02-1000. If this is what you are needing I would need to know what weight rating you need for your system. If you are wanting to use it as an adjustable ball mount the Ball Mount Adapter # BA-1 does share the same 3/4" bolt holes spaced 1-1/4" apart. It will require a hitch ball that has a 1" shank. 1-7/8" Ball # 19260 2" Ball # 40038 2-5/16" Hitch Ball # C40005 Another...

  • Can 2018 Toyota Highlander Use Ball Mount WIth 2-5/16" Ball
    If your question is can you use a ball mount with 2-5/16" ball with your 2018 Toyota Highlander Hitch, yes you can. More than likely you have a Class III hitch with a 2" receiver like the # e98844. This can use a ball mount that fits a 2" receiver like the # C45041 which has a 2-5/16" ball and a hitch pin and clip. If you are referring to your ball mount, or draw bar, like the Draw-Tite Ball Mount for 2" Hitches # 2923 then you need to match the shank size to the ball hole diameter. This...

    Yes, the Buyers Products Trailer Hitch Ball item # 337RB2516 can be used with a standard ball couple when it is mounted with a Pintle Hook like the item # 337RM62516. Just to add the Pintle hitch ball you were referencing the Buyers Products Replacement Ball item # 337RB2516 has a ball size that matches the standard type of hitch ball but the size of the shank is larger on a pintle.

  • 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.

As you mentioned you are only towing the trailer once the best option is to use a Curt Friction Sway Control # 17200. This will require you to use a Curt Ball Mount w/ Sway Control Tab # D320, and either a 2" Hitch Ball # A-90 or 2-5/16" Hitch Ball # C40005 to match the trailer coupler.

So what you can use instead is a dual ball mount/hitch adapter: - Curt Multipurpose Ball Mount with 2" Receiver # D210 The # D210 has capacities of 7,500 lbs towing/750 lbs tongue weight so it's more than enough for towing your trailer and...
