Video Transcript for Review of Curt Hitch Ball - Trailer Hitch Ball - C40030

Today we're going to take a look at the CURT two and five sixteenths diameter long shank chrome hitch ball with a 15,000 pound weight capacity. Now, this hitch ball provide a connection point for your trailer's coupler. Does use find threads to provide a nice tight, strong grip. It's a treated steel which is very durable, has a nice corrosion-resistant chrome finish to it. If you notice these flat edges right here, these are built-in wrench flats that make it very easy to hold the ball in place while you're tightening the nut. Now, the lock washer and the nut is all included for installation.

Again, the ball diameter on this is two and five sixteenths of an inch. The weight capacity, which is stamped on the top of the ball, is 15,000 pounds.Just to give you a few dimension on this, we're going to measure the shank diameter, which is going to be right at one and a quarter inch diameter, and the length of it from the bottom to the end is right at two and five eighths inches long. It is designed to fit ball platforms from three quarter inch to one inch thick. But again, you'll just drop this through the hole in the ball mount, put your washer on, put your nut on, and then just tighten it down and torque it to the factory specs. But that should do it for the review on the CURT two and five sixteenths inch long shank chrome hitch ball with a 15,000 pound weight capacity..

2-5/16" Hitch Ball - 1-1/4" Diameter x 2-5/8" Long Shank - Chrome - 15,000 lbs - C40030

Average Customer Rating:  4.9 out of 5 stars   (3388 Customer Reviews)

Durable steel ball has a 1-1/4" diameter x 2-5/8" long shank. Built-in wrench flats ease installation. Chrome finish resists corrosion. Fine threads provide strong grip. Lock washer and nut included.


Quality is fine. The experience is the reason for the 3 star rating. This ball does not fit the ball mount you sent, and I didn't figure it out until it was too late to return. As always, helpful, friendly staff, but this order had a couple of things the didn't match up. For example, the ball mount did not come with a pin to hold it into the receiver. As a novice, it would have been helpful to have your staff identify this.

I am sorry that the incorrect ball was recommended. I see from your order that you bought ball mount part # C45030
Curt Ball Mount for 2" Hitches - 1" Rise, 2-1/4" Drop - 7-5/8" Long - 7,500 lbs
which has a one inch diameter hole. A 2 and five sixteenth ball that would work with that ball mount would be part # C40005

Very good quality. Original shipment box was damaged and this item was missing. etrailer reshipped me a replacement very quickly with no questions. Great customer service.


I put a trailer hitch on my 2012 Chevy Cruze. I don't use it very often. It went on easily as did the wiring harness. I'll use it more this summer. Two thumbs up.

No issues ever. Will contact you when I purchase a Mustang.
David - 02/05/2018


Good price for the capacity. Will be fine with my 1 inch thick drawbar. Note that the recommended torque spec is 450 ft-lbs; I purchased a digital torque adapter for the installation.


This product is well made, preforms well and is easy to adjust. The brake pad shows very little ware after 5,000 miles. The paint finish appears to hold up well and is very durable.


Received the advice I needed fro sizing the trailer hitch for my trailer. Plus speedy delivery of my order. Thanks Jacob!


This hitch ball is bomber.


I upgraded to this ball as I also ordered a 14,000 # convert-a ball with a 1.25 inch hole to pull my new dump trailer. Is a very nice setup with the dampening feature.

Seems to be working as I expected
Monte E - 07/20/2022


Good solid product exactly as advertised. Goid company to purchase from.


As it should be. Bought to go on an equilizer weight distribution hitch. Works great and good bang for the buck.


Perfect hitch ball for towing my 11,000 pound boat & trailer. 3,000 towing miles so far and all is well.




The ball works and is rated higher than my hitch.


UPS delivered the ball but not the hitch

Oh no! I will have our Customer Service team reach out to assist in tracking the packages.
-- Etrailer Expert Jenny N - 11/21/2022


Looks heavy duty and can easily handle my trailrt


Got this hitch for my 2014 Ram 2500. It came with an adapter to use standard 2" ball mounts I already had from my old truck. The adapter wobbled and rattled so put some duct tape on it. That stops the rattle but makes it hard to change ball mounts!

I got this correct size ball mount and now no rattles or problems! Looks better too. Great Finish and welds. I got the matching Curt 2-5/16" ball and all is good now!

Ball is still going STRONG!
John G - 12/05/2017


Worked as advertised. No issues after one year of use.


Really nice finish and quality for a good price. The flats are helpful to torque to what? 450 foot pounds?
I know turn the 2 inch square ball mount 90 degrees and stand on my 1 inch drive torque wrench, but I only weigh 155. Do the math, a cheater pipe 3 feet long.


I own a 31ft Cabin Cruiser boat that weighs around 10,000lbs and the trailer itself weighs over 2000lbs. Every time I would pull the boat out of the water the back of my truck would squat a little and the trailer jack would occasionally scrape the ground. So I purchased this Hitch Ball and mounted it upside down so that the ball is higher than the bumper of the truck and now the trailer is level when cruising down the interstate fully loaded.

This Hitch ball is very heavy and completlely solid! I dont hear any noises coming from the hitch at all.

Etrailer had the best price around and will always contine shopping with them anytime I need any trailer parts


Bought this hitch to use on a Jayco toy hauler at a dealers recommendation who sold several different types of load distribution/stabilizer products. Worked great so I bought another one for our new North Trail which is same size but 1/2 the weight. Only this time I installed it myself. Support from etrailer was excellent. They know their product. I actually ordered the wrong weight bars, and another part was missing and we had a trip scheduled! They got us the parts ASAP and we were ready to go with time to spare. One point of caution: When installing the ball, it requires 400 lbs of torque. I took this to a truck repair shop and did it for me free in just a minute.


Preston and Ian were outstanding to work with and get the proper fit for my truck and trailer. Very detail oriented and everything they told me was spot on. Thanks guys!

Very happy with the towing system and have put over 20k miles with them.
Paul - 05/22/2019


The Reese weight distribution hitch would likely work fine for a trailer somewhere between 20-28 feet. Been towing for years, and find it does distribute the weight nicely onto the truck. However, with a long trailer (I am towing a 36 foot Rockwood with the weight of 3 large slides), you're going to have highway speed sway every time. There is just no two ways about this. Dialing it in precisely, new shocks, new tires, new truck - 3/4 ton to a one ton, is not going to fix it. The passing semi trucks will get you side to side if traveling at 50 mph or more, and it is uncontrollable at times. If you go with this hitch, you will be avoiding highways like the plague, trying to make sure you don't lose your trailer and more. Just spend the extra money and get a Hensley or Pro Pride hitch. They are the only hitches that work for weight distribution AND sway elimination on long trailers. If those are too pricey, seriously think twice about purchasing a long trailer - you will never have the same issues with a fifth wheel.


It's a ball... But a nice one. Want real reviews? Ask me in three months what I think. Not the day after I got it... Service from eTrailer was aok. Fortunately UPS lets us upgrade shipping from USPS delivery to UPS straight through. The ball appears to have heavy chrome. That will be a plus!

Great product! I got it because of the high end specs. I have a equipment and a dump trailer. Never have to worry about exceeding the GVW and TW of that ball! Peace of mind is great...Best regards,
Dan F - 07/20/2015


Received the ball mount and other items in their original packaging which was nice.
The finish is a good powder coat, and the items should hold up to my demands.


Item was well packaged for shipment arrived with no damage.

  • Hitch Ball Recommendation that is 2-5/16 Diameter with 1-1/4 inch Diameter Shank
    Sounds like you are looking for a 2-5/16 inch diameter hitch ball with a 15k capacity that has a 1-1/4 inch diameter shank. For a hitch ball that fits your criteria exactly you would want the part # C40030. If your ball hole is .03 larger than the diameter of the hitch ball you install into it you would be totally fine.

  • What Size Wrenches are Used to Tighten the Curt Hitch Ball Part # C40030
    Yes, I went out into our warehouse to measure the nut of the Trailer Hitch Ball # C40030 and found that a 1-7/8 inch wrench would be the correct size. The same size wrench would be used for the top portion of the ball as well.

  • Wrench Size Needed to Install Nut on Curt Hitch Ball C40030
    The Draw-Tite 2-5/16-Inch Hitch Ball # C40030 will require a wrench or socket in the 1-7/8-inch size in order to torque the included hex nut that secures the ball to the ball mount.

  • Weight Distribution Recommendation for Trailers with Gross Weight of 7,000 Pounds
    To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. If the gross weight of each trailer is 7,000 pounds that would put the tongue weight range at 700 to 1,050 pounds. Based on that I recommend going with the 1,000 pound system # C17052 over an 800 pound system....

  • Tongue Weight Capacity of Curt # C17057 Round Bar Weight Distribution System
    The spring bars used in weight distribution systems will work over a range of tongue weights. The Curt # C17057 round bar weight distribution system has a maximum capacity of 14,000 gross trailer weight/1400 lbs tongue weight. That's the maximum, but the system is effective on trailers with tongue weights ranging from 1000 to 1400 lbs. In order to choose the correct system, you'll need to find the fully loaded and ready to tow tongue weight of your trailer. You'll also need to include...

  • Correct Weight Distribution System for 38' Bayridge Park
    If you're just looing for a basic cost effective weight distribution system I recommend the Curt MV Weight Distribution System part # C17057 which is rated up to 1,400 lbs so there will be plenty of room for error. The only thing you'll need to complete the setup is a hitch ball, 2-5/16" part # C40030.

  • Replacement For 1,000 lb Pro Series Weight Distribution With no Replacement Bars Available
    The Curt spring bars you mentioned won't fit a Pro Series weight distribution hitch as they are not designed to fit that head unit so they won't work. There are no longer Pro Series replacement bars available as they stopped making that version of hitch, so the only option available is a new system. Since you mentioned you had 1,000 lb spring bars you can use a similar Curt system: - Curt MV Weight Distribution System - Round Bar - 10,000 lbs GTW, 1,000 lbs TW # C17052 This is the most...

    You will want the Curt TruTrack Weight Distribution System w/ Sway Control # C17499 for your 2018 Forest River Wildwood M-171RBXL. This system is rated for tongue weights of 500-800lbs with a maximum trailer weight of 8,000lbs. For your current tongue weight of 521lbs and adding 40lbs for the 2-20lb propane cylinders, 50lbs for the battery and box will put you at 611lbs. This leaves you with 189lbs of additional gear on the front of your Wildwood. You do not need to include the weight...

  • Can You Tow More When Using Weight Distribution Hitch on 2004 Dodge Ram
    You can increase the weight capacity of a trailer hitch in some cases by adding a weight distribution system like the Curt MV Weight Distribution System part # C17051 (Add 2-5/16" Hitch Ball part # C40030). If so, it will be printed on the label of the hitch as you noticed. That being said, trailer hitches are tested separately from the vehicle so you need to verify the towing capacity of the vehicle and then abide by the lower of the two ratings whether that's the hitch or vehicle.

  • Recommended Ball Mount To Use A 2-5/16" Hitch Ball
    I have another option for you, but all of our 2-5/16" hitch balls have at least a 1" shank diameter. Instead I recommend replacing your ball mount to accept a hitch ball with a larger shank like the Curt Ball Mount for 2" Hitches # C45310 which uses hitch balls with a 1-1/4" shank. This would allow you to use the Curt 2-5/16" Hitch Ball # C40030. I included videos to each of the products mentioned for you to take a look at.

  • 2-5/16" Hitch Ball to Tow 14,000 lbs
    There is a 2-5/16" hitch ball that with a capacity of 13,000 or 14,000 lbs, though you do need to make sure the hitch ball will fit your ball mount. This means the ball needs to have a shank that has a diameter as well as length to properly secure to your ball mount. Additionally, keep in mind a hitch ball with a larger capacity will not mean you can tow more if your hitch and/or vehicle is not rated for 13,000 or 14,000 lbs. The most common shank diameter is 1-1/4" and for that I recommend...

    The Hidden Hitch Model 40022 is a very old system and they do not offer replacement spring bars for this anymore. That said, we have an excellent option for replacement and it's very cost effective, the Curt MV Weight Distribution System part # C17052 which comes with everything you need except the hitch ball (2-5/16" Hitch Ball part # C40030) and has a 10,000 lbs / 1,000 lb weight capacity.

  • Can Curt Weight Distribution System # C17057 Use 2-5/16 inch Hitch Ball
    Yes you can use a 2-5/16 inch hitch ball with the Curt weight distribution system part # C17057 that you referenced. For that the part # C40030 would work great. You are over the tongue weight rating of your current system so it would be time to upgrade and the Curt # C17057 would work great.

This system is designed for use on trailers with tongue weights between 800 pounds and 1,500 pounds, and it has a gross towing weight capacity of 15,000 pounds. The Steadi-Flex system uses spring bar hangers with integrated friction pads to help stop sway, and the trunnion bars work to distribute the tongue weight of the trailer without compromising ground clearance like more traditional-style...

    The Curt trailer hitch balls are all made in China. Many trailer hitch receivers too are made outside the U.S. but Curt does manufacture their hitches stateside. The 2-5/16-inch hitch ball you referenced, Curt # C40030, has a 15K gross trailer weight capacity. For a comparably-rated 2-5/16-inch chrome-plated ball that is made here in the U.S. you can use B&W part # BWHB94004. This is rated for 30,000-lbs. Its shank is 1-1/4-inches in diameter and 2-1/2-inches long.

  • Best Weight Distribution for 2014 Ram 2500 and Trailer with 1,322 Pound Tongue Weight
    To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. An 800 pound system is rated much too low for a tongue weight at 1,322 pounds. You will want a system that is rated for 800 to 1,500 pounds such as # RP66130 that you have referenced.

    The best way to choose a weight distribution system is to know your total tongue weight. The total tongue weight is the tongue weight of the trailer when it is fully loaded and ready to tow added to the weight of any cargo placed behind the rear axle of the towing vehicle. Tongue weight is normally between 10 and 15 percent of the loaded trailer weight.

    Yes it can! If you check out the attached picture from the installation instructions for the Reese Steadi-Flex # RP66560 you referenced you can see that it is compatible with underslung couplers. You simply need to install the adjustable frame bracket so that the mounting bolt is fastened to one bolt hole below the bottom bolt on the frame bracket.

    It sounds like you are looking for the socket required to install the nut on a 2-5/16" hitch ball like the Curt # C40030 you were looking at. You will need a 1-7/8" socket like the 1-7/8" 12pt Thin Walled Socket - 3/4" Drive - Chromium-Vanadium Steel # ALL643216. You will also need a torque wrench that has a high enough rating for the torque your specific hitch ball required. I included videos of the products mentioned for you to take a look at.

  • Do The Different Hitch Ball Sizes Have Different Heights As Well?
    From the bottom of the flange to the very top of the ball will indeed be 2-3/4". This can vary slightly between manufacturers and ball size though, but the typical 1-7/8" ball ( # 19256) will measure +/- 2-5/8" tall, the typical 2" ball ( # 63845) will measure +/- 2-3/4" tall, and the typical 2-5/16" ball ( # C40030) will measure +/- 3-1/8" tall. With that said, you should not be relying on the height of the ball to figure out how much rise or drop you need. This should be done by measuring...
