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

Today, we're gonna be taking a look at the CURT Trailer Ball. So this one's gonna be a 2 5/16 inch ball. It's gonna have a capacity of 20,000 pounds. So we do want to match this up with a ball mount that's gonna be able to carry at least that much. So with this ball mount, it's about 21,000 pounds. So we are limiting our ball mount by 1,000, but that's not necessarily a huge deal.

But if you did need to grab a ball mount, just make sure it kinda lines up, 'cause you do need to piece these things together just to make sure that they're all gonna work together. Might as well not limit yourself from right off the bat. Another thing to think about is which ball mount you're gonna pick, but also the thickness. So we wanna make sure that we're gonna have a platform that's at least 3 1/8 of an inch thick. So this one's totally fine.

And then looking down at the shank, we do need to make sure that the hole is going to be an inch and 1/4 in diameter, because that is the diameter of the shank of the ball. Let me take this off real quick. There we go. So as you can see up top there's hardly any play. We really want to line this up and make sure it's the same size, just because if it's any bigger, the shank, it's not going to put the ball mount and any smaller, there's going to be a lot more play.

And we really don't want that. Especially with these really heavy duty balls. We wanna make sure they are nice and snug in there just so we don't have any issues whenever we go down the road. So if you we're to upgrade with a trailer ball, I guess you could get one that's forged and machined out of one single piece of steel. This one's made of steel.

It's gonna be plenty strong, but it has a Chrome finish. The other one's just going to be a little bit stronger. But I really don't think that really matters a whole lot. One thing I would pick up is some grease for this just because there's a lot of grinding action that goes on. And with that grease, we carry here at etrailer, it's just gonna keep this finish looking nice for a little bit longer. When it comes to trailer balls, there's some that are gonna give you an inch or two in rise, so the ball itself will give you a rise. If that's something that you're interested in, you can get that here at etrailer. But this is just your standard 2 5/16 inch ball. And that's basically it for our look at the CURT 2 5/16 inch Trailer Ball..

2-5/16" Hitch Ball - 1-1/4" Diameter x 2-3/4" Long Shank - Chrome - 20,000 lbs - C40008

Average Customer Rating:  4.9 out of 5 stars   (3550 Customer Reviews)

Durable steel ball has a 1-1/4" diameter x 2-3/4" long shank. Chrome finish resists corrosion. Fine threads provide strong grip. Lock washer and nut included.

The Curt ball hitch worked perfectly for my needs. I installed it on a Blue Ox weight distributing hitch that came with an unusually low ball causing my trailer coupler to contact the hitch head. This ball is a bit over 1/2" taller, which solved the problem. I chose this particular one because the flange that seats against the hitch looked the largest out of the offerings, so I figured it would provide some additional strength. Great ball that yielded great results for me.



by:

Shipper lost the order but etrailer shipped me a replacement. Great service



by:

It was one of the few things that gave me enough drop to hook my Truck up to my small utility trailer! hook my Tahoe up to my small utility trailer



by:

Nicely plated and fits well. Without flat spots on the base to hold, I was afraid the ball would slip and turn while I tightened the nut, but I had no problem installing it on the Curt ballmount. It has great capacity, and I have no worries about it safely pulling my boat.

Works well. Has stayed tight and does the job to haul a 4 ton boat and trailer



by:

This ball mount has served it purpose well. I purchased a new travel trailer that is heavy enough to require a weight distribution hitch when using the factory installed Class III hitch on our Dodge RAM 2500. I decided to upgrade to a Class V hitch combined with this ball mount to take delivery of the TT in order to defer decisions about a WD hitch until the actual load conditions were known. The hour trip home with this setup worked very well. Once the trailer was outfitted I was able to determine the actual tongue weight of the loaded trailer and I decided to purchase an appropriately sized Reese Straight Line WD hitch. However, this ball mount comes in handy for moving the trailer short distances without hassling with the WD system. The purchase experience through etrailer.com was first rate.



by:

No one had a 2 5/16 inch ball in 14000 tow weight. As we had to move our trailer and as I called numerous dealers and was told not available, I reached out to etrailer. They also didn't have it but suggested I go larger in the ball so long as it fit the tow hitch and the shank. It did I'm still using it and am very happy with the product and the quick service and turn around with my order.

simple design
and easy use makes this a winner in my books.

Great product, gives me total confidence in my ability to pull my car trailer. etrailer is a great company to deal with.

So far I have pulled my trailer over 10k miles with my ‘16 Ram 2500. The hitch is easy to use and really helped with sway even when empty. Best choice I could have made for my trailer.



by:

I received everything that I requested in a short time even with the free shipping. The ball mount and the balls I requested and the 2-5/16th ball and the 2" ball were just what I needed. the ball cap for the 2-5/16 ball fit perfect the ball cap for the 2" was really just made for the smaller ball. I would recommend that they make a ball cap for just the 2" ball. Got it to fit but not that well. I will need breaks for my boat trailer after this season and I plan on using etrailer for those parts. will need to call them before I make purchase as Im not sure how to size them up.



by:

Great Ball, works perfectly. The nut is BIG so make sure you have a big enough socket to tighten this monkey up! Put it on the hitch, then put the hitch in your receiver sideways so you can get better leverage to tighten the nut.



by:

I ordered a Class V ball and ball mount with pins. This is for the 2.5 inch heavy duty receiver. I needed a set-up for pulling an emergency services boat that weighs over 18,000 lbs.

I was able to get a set-up rated at 20,000 lbs, in stock. Shipping was fast and quality looks good.



by:

Good, solid product. We tow our 15,000 lb boat behind our Ford F-250 using it. You do need a pretty long torque wrench to tighten the nut to specs, and because there are no flats on the ball end, you have little choice but to damage the chrome plating in the throat a big with a pipe wrench as you tighten. But no big deal.



by:

This hitch ball looks good - the chrome finish looks too good to hook a trailer up to and it meets the weight ratings I was looking for, which is clearly stamped on the top of the ball. Now I just have to torque it up to the 450 ft lb spec required as stated on the attached tag and I will be good to go.



by:

Well constructed



by:

We always call etrailer, first, whenever we need anything for our Motor home or our trailer. They are so knowledgeable and supportive, it takes all the worry out of ordering wrong. They even helped us with ordering Thule carrier and cross bars!

Thank You!!!!



by:

We liked the results of how well the Reese weight distribution and sway control system so much that we went ahead and ordered the parts needed to set up a second vehicle to tow the same trailer. Reese and etrailer.com have made preparing for and towing the race car hauler a breeze! We couldn't ask for a better combination...



by:

Carol, when I have a chance to install the hitch I will. I am waiting on delivery if my hitch. Can I ask you to confirm the nut size on the Curt 2 5/16 the ball. I think it is 1 7/8" but cannot find it anywhere on your site. I called and your support person thought 1 13/16, but was not sure. Tks!



by:

Fit just like the original ones and work great!



by:

For the price I could pass it up.working well towing a 16k dump trailer.

Better than expected



by:

The heavy duty hitch and other parts that I received from etrailer were exactly what I ordered and at a good price. The delivery was fast and nothing damaged. Thanks etrailer I will be buying from you again.



by:

This hitch ball is stout!! It’s heavy and dense and made very well. This is the second one I have purchased, as this one will be installed on a lower drop Curt hitch.



by:

Nice chrome trailer ball. Installed easily on the new hitch.



by:

Just as described. Its a Chrome 2-5/16 ball that works well with the Curt C45340 hitch.



by:

Great folks to deal with, good products at good prices. Free shipping was a sell point because of how heavy the order was. ( Ordered the cast steel hitch with this ball as well)



by:

eTrailer called as the part ordered was not available and they asked to substitute with an equal product so that we could get the order quicker. Perfect!

  • Recommended Blue Ox SwayPro Weight Distribution System For 30 Foot Trailer
    The Blue Ox SwayPro Weight Distribution w/ Sway Control - Clamp On - 15,000 lbs GTW, 1,500 lbs TW, # BXW1500, may be a good fit for the weights and dimensions you gave. The maximum gross towing weight is 15,000 lbs and the maximum tongue weight is 1500 lbs. You will also need a hitch ball that is either 2 inches like # 63840 or 2-5/16 inches like # C40008. This system will give you up to a 13 inch rise or a 7 inch drop which will accommodate your 2 inch need from shank to top of hitch...

    We can get you set up with the perfect option for a weight distribution hitch with sway control for your 4,800 lb GVWR trailer. First let's talk about he correct rating, and it isn't double the capacity of the hitch or hitch weight, the right system is going to be one in which your loaded tongue weight falls in the middle of the weight distribution system's tongue weight capacity. And since tongue weight is in the 12 to 13 percent range of your trailer's GVWR, your trailer's tongue weight...

  • Recommended Curt Weight Distribution System for a 2015 Keystone Hideout 260LHS
    The Curt Weight Distribution System I recommend for a 2015 Keystone Hideout 260LHS is the Curt TruTrack Weight Distribution System part # C17499. The TruTrack has integrated sway control which will do a much better job than systems with add-on sway control such as the Curt Weight Distribution System part # C17341 with the Curt Friction Sway Control part # 17200. Furthermore this option does not require drilling into the trailer frame, it offers easiest setup, and does not restrict the reverse...

  • Weight Distribution for an RV on Ford F-550 Chassis Towing 9,000 Pound Car Trailer
    The Ford F-550 chassis is up in the medium duty range but with the weight of the RV body on it and the tongue weight of the trailer at 1,000 pounds, you would likely still benefit from weight distribution. A good rule to go by is if the loaded trailer gross weight is at least 50 percent of the vehicle weight, or if the vehicle sags at the back when connected to a trailer, weight distribution is a good idea. To choose a weight distribution system you will need to go by the total tongue...

    The weight distribution system I recommend for a 2020 Gulf Stream Kingsport 248BH is the Curt TruTrack Weight Distribution System part # C17499 which will have you covered while empty or fully loaded. This system is a great option with integrated sway control so not only do you get the reduced sag/squat you also get better control of the trailer on the highway. The best part of all is that it's all bolt-on and pretty easy to setup. In order to complete your setup you'll also need part #...

  • Can Friction Sway Control be Used with Reese Strait-Line Weight Distribution System
    The mounting space for the dual cams on the 17K Strait-Line Weight Distribution w/ Sway Control # RP66075 will actually overlap with the space for the mounting plate of the Reese Friction Sway Control Kit # 83660 so they can't be added together. If you check out the attached video for just the Dual Cams # RP26002 you can see where we removed the older-style sway control so we could install the cams. The Strait-Line with the Dual Cams is actually one of the best weight distribution systems...

  • Recommended Weight Distribution System for a 15,000 lb Box Trailer
    I do have a solution for you but unfortunately you do have to use a TorkLift XL Shank like part # TLM9011 along with the SuperHitch on your tow vehicle to be able to use the Everest Weight Distribution System # TLWD1000. If 15,000 lbs is the GVWR (gross vehicle weight rating) of your trailer or that is the most it will weigh when you are towing it then you can potentially use the Strait-Line # RP66075 instead. This is rated to tow up to a 17,000 lb trailer and it has a tongue weight (TW)...

  • Can the Ball Mount # C45340 be Ordered with the Curt Hitch Ball # C40008 Already Installed
    I do have a solution for you, but we do not install parts like the Curt Heavy Duty Forged Ball Mount # C45340 and 2-5/16" Hitch Ball # C40008 before shipping them out. Any ball mounts that come with a hitch ball installed come like that directly from the manufacturer. If you do not need the full 17,000 lb capacity of the ball mount # C45340 that you referenced then you can use the Curt Heavy Duty Forged Ball Mount # C45331 which is essentially the same exact ball mount with a 2-5/16" hitch...

  • Reese Weight Distribution With Sway Control That Works With 2-1/2 Inch Trailer Hitch Receiver
    We can get you set up with a Reese weight distribution with sway control, and that's a smart choice as their Strait-Line models offer superb control due to their dual cam system that control the spring bars and apply pressure and tighten at sudden movement. Getting the right one for two different trailers will be difficult though unless they have a very similar loaded tongue weight, because the correct system would be one in which your trailer's tongue weight falls somewhere in the middle...

  • Weight Distribution Recommendations for 10K Enclosed Car Trailer
    Anytime the weight of a trailer exceeds 50% of the vehicle's weight (which it does, in this case) weight distribution is highly recommended. Because enclosed trailers have a large surface area on the sides which act like the sail on a boat when impacted by crosswinds or turbulence from oncoming or passing traffic, using a weight distribution kit with an integral sway control component is also highly recommended. Weight distribution will level out the ride height between the truck's front...

In regards to the platform, I spoke with a representative of Curt who told me it was 1" thick; in addition, the diameter of the hitch ball hole is 1-1/4". For a 2-5/16" hitch ball with a 20,000 lb capacity the Curt # C40008, which has a 2-3/4" long and 1-1/4" diameter shank, would work, or if you need a 2" hitch ball the Curt # A-90 has a 10,000 lb capacity with a 2-5/8" long.

  • Thickness of Hitch Ball Platform of B&W Heavy-Duty Ball Mount

This ball mount has a 16,000 lb capacity and 1,600 lb tongue weight capacity while giving you either a 1 inch rise or 2 inch drop. To secure it to your hitch you'll need Pin & Clip # PC3. For a hitch ball, depending on the size you need, I recommend either 2" Hitch Ball # C69FR or 2-5/16" Hitch Ball # C40008. I have added a link to a video review for you to check out as well...

  • Will Brake Actuator Cause Trailer Sway
    I have never heard of a brake actuator being the cause of trailer sway; you mentioned higher speeds, and without a form of sway control, that's going to naturally occur more the faster you go. I can't give you any specific amount of movement in the tongue, but if you're mostly experiencing sway at higher speeds, you can help remedy the issue with a weight distribution hitch with sway control. The Reese Steadi-Flex is compatible with surge brakes and the right one depends on your tongue...

  • Recommended Weight Distribution for Trailer With 1600 lbs of Tongue Weight
    Whew. That's one heavy trailer! As long as the trailer tongue weight won't exceed 1600 lbs, the # EQ64FR Equal-i-zer Weight Distribution System would be ideal. This particular system is meant to be used in a Class V hitch with a 2-1/2 inch by 2-1/2 inch receiver. This is the highest rated system Equal-i-zer offers. If your trailer's tongue weight will exceed 1600 lbs, the next step up is the Reese # RP66075 Strait-Line, good for up to 1700 lbs of tongue weight. The sway control component...

  • Width Dimensions for Mounting the Reese Super Titan 4000 Trailer Hitch on a 2000 Dodge Ram 3500
    The Super Titan 4000 Trailer Hitch # 38208 is actually designed to fit a C-channel frame. To determine if it will fit your 2000 Dodge Ram 3500 you just need to make sure that your frame is about 34" - 34-1/2" wide and is at least 8-3/4" tall. I spoke with my contact at Reese who said that the outside dimensions with the spacers is 34-1/2" but when you remove the spacers you get the 34" width.

  • What Weight Range Weight Distribution for Trailer with 1,400 lbs Tongue Weight
    If you have a tongue weight of 1,400 lbs a weight distribution with a higher tongue weight range would be ideal. Especially when you consider that the weight of any cargo behind the rear axle of the tow vehicle gets added as additional tongue weight. So a higher rated system like the Equal-i-zer part # EQ64FR would be your best option as it has a tongue weight range of 1,200-1,600 lbs. You'll also need a thin-walled socket to install the ball # C40008 too with the # ALL643216.

The Reese excels at maintaining towing in a straight line especially when outside forces like passing trucks and wind gusts push on the very large sides of your trailer. The cam system is more rigid when in a straight line and the 1200 pound tongue weight rating gives you that little extra strength you will occasionally need.

  • Weight Distribution and Sway Control Recommendation 2018 Jayco Eagle 322RLOK
    The best weight distribution/sway control systems are the Equal-i-zers like the part # EQ64FR you mentioned but the trick is picking out a kit that the trailer's loaded tongue weight falls right into the middle of. This system has a tongue weight range of 1,200 - 1,600 lbs. I looked up your 2018 Jayco Eagle 322RLOK and based on the dry weight, dry tongue weight, and GVWR this would be a great option rated perfectly.

If you do not have a torque wrench rated up to 450 foot pounds in which case you'll never really measure it at 450. When tightening the ball you want to make sure you get the lock washer, so that it's completely flat. One way to make it easier on you is to put the ball mount in your hitch receiver sideways so the hole is vertical. Then install...
