Video Transcript for Curt Long Shank Hitch Ball Review

Today, we're going to be taking a look at Curt's two-inch hitch ball with a one and a quarter inch diameter shank. Part number A-90. This is what our ball's going to look like when it's installed on a ball mount. A ball mount doesn't come included with your ball, but you can pick up various ball mounts here at to match it. You want to make sure that whatever weight rating your ball is, the rest of your components match it because you never want to exceed the towing capacity of the lowest amount. If your hitch is only rated for 8,000 pounds, but your ball mount and your ball are rated for 10,000, you don't want to tow more than 8,000 pounds.This is a two-inch ball with a one and a quarter inch diameter shank.

It has a 10,000 pound weight rating and a chrome finish to protect against rust and corrosion. You want to make sure when installing your ball in your ball mount that it has the appropriate size diameter hole that matches the shank for your ball. So, since this is one and a quarter, we want to make sure our ball mount has a one and a quarter opening.The ball itself is made of steel, so it's going to last you a long time. The length of the shank coming off of our ball is going to measure two and five eighths inches. This is important when determining if it's going to fit in your ball mount, and if you have any accessories that installs along with it that the shank will be long enough to properly install the nut and still have some threads poking through the bottom.

Some accessories you may want to install with your ball when putting it on you ball mount may be an anti-sway for a camper you're pulling behind you.Because this is a two-inch ball, it's going to work with two-inch couplers. If the coupler on your trailer has a different size, you can pick up those here at Most common sizes are one and seven eighths, two inches, and two and five sixteenth inches.Brophy makes a two-inch hitch ball with a one and a quarter inch diameter shank. However, this ball is only 7,500 pounds and has a two and a quarter inch shank. So, our Curt here has not only a higher weight rating, but a slightly longer shank so it'll be a little bit more useful with more accessories and have higher towing capacities.Now, we'll show you how to get it installed on your ball mount.

We've got an older unit here, so as not to mar up a brand new unit. You'll want to install it in a vice as this does torque to a very high foot pounds. You'll set your ball mount on it in whatever position you'd like. So, we've got a drop or rise here, we're going to be putting it in the drop position.After you've got your mount on, you'll slide on the washer followed by the nut. We're going to a use a one and seven eighths inch socket for this ball here.

Same procedures are going to be similar for this ball mount as in any other ball mount. Although, your socket size and torque spec may vary. We'll then just torque it to the specifications.We can now take it out of the vice and we're ready to put it in our hitch. Now, if you don't have a bench vice to hold your ball, you can put an adjustable wrench on it, slide it into your hitch receiver, and that will just butt up against the side of it. Depending on your ball mount, it may vary if it would hit there, so what you can do is you can also turn it sideways and have that wrench swing up and hit on your receiver. You'll have your wrench on the ball mount side and your torque wrench on the nut side tighten it down.And, that completes our look at Curt's two-inch hitch ball with one and a quarter inch diameter shank.

A friend who has towed 9000lbs+ boats, recommended you, and thankfully, I took his advice. The person who answered my call last year was very knowledgeable and gave ne excellent advice for my towing problem(front end sway) and advised me to purchase a proper sway and load hitch, which I did and installed(even made a roll-around" to store the heavy items when not in use).
Thank you for excellent service, bruce

Although I dont tow 10,000 pounds, the extra strength gives me piece of mind for a few more dollars

Great Hitch Ball. Received it well-packaged and very quickly. It threads more easily than any other Hitch Ball I've owned. Love etrailer!

After using this Hitch Ball quite frequently, its always been fantastic! Glad I bought it, and, glad for etrailer!!!
Nasty J - 04/25/2023


The FastWay e2 hitch arrived missing ALL the assembly hardware so I cannot assemble or rate this product. I like a lot but your shipping company is a constant let down. Clearly the box for the e2 hitch has a big rip in it that was cheaply taped up with a bit of weak packaging tape. I don’t think you shipped it that way. Several other times I paid a lot extra for fast shipping but that failed every time. My most recent previous order was paid for 3-day shipping only to arrive 6 days after you sent it out. This happened at least three other times so I obviously won’t try that again. Love the products. Love the videos. The best way for you to improve our customer experience is to get a decent shipping company. UPS just can’t do the job.

Wow I am so sorry to hear that you are missing all the hardware! I will send your information to our customer service team and get you squared away! I will have them look into the shipping costs as well.

Still working great after a year mounted on our Draw-Tite 4285 Ball-Mount/draw bar. Be aware that it may require professional help to mount it to the required 450 lbs of torque. I managed to use a "cheater bar" plus torque wrench to do it myself with 75 lbs of arm strength applied to the wrench, as shown in pics. I had to support our hitch on blocks, since 450 lbs of force exceeds our hitch's 350-lb rating.


I got great support from etrailer on choosing the right ball mount and ball for my hitch. The product came in great shape and earlier than expected. I appreciate etrailer's excellent customer service.


Excellent hitch for the price. Just what my minivan needed after struggling with other types. Made a big difference in pulling my 3000 lb camper. Very easy to set up. I ordered the correct 1 1/4 inch ball shank for a proper fit.


Hitch is fine, packaging is smashed due to how was tossed in un-secured into huge box with receiver.


I should have looked closer, the OD of the threaded portion is 1!/4" and the hitch is 1" exactly.


What can I say - it is a towing ball. I have a rather large landscape trailer and this is just the ball needed to pull it with some safety margin above the trailer's GVWR -- this is about the highest rated 2-in ball I have seen before jumping up to the 2 5/16" balls usually reserved for campers and other larger bumper pulls. The only negative I have seen on this is the torque rating, which is what it is.

450-ft-lbs -- you better have a [**] beefy torque wrench, be willing to buy one, or know someone who does. Given the cost of torque wrenches above 300 ft-lbs it would be a really nice option if etrailer would offer service where the ball can be delivered pre-torqued on the drop or raise shank of your choice.

I stand behind my initial review though point of clarification. I ordered the ball in 2019, posted a 1 year review in 2020. And now they are asking me for another 1 year update....well 2 years later it is still solid.

I needed a longer receiver for my bass boats so that when turning on the boat ramp, the bass boat steps i boat would hit my bumber. The person how helped me took his time and found the products I needed. Everything was great heavy duty, perfect!!!!! Gone fishing


It's a hitch ball; not much to say about it. Very shiny.


Still looks great. Only problem I had was finding someplace where I live that would tighten the nut to the recommended torque amount. It was way higher than any torque wrench I had

still doing great.
Steven - 08/15/2022


The smaller items were just tossed in the larger box with the receiver. So the box has several holes in it and the wiring harness was laying on the ground next to it when delivered. Also, the locking pin was well overpriced.


After balking at the cost to have an auto-shop add a trailer to our Toyota Highlander, we found and decided to take a chance. The "how to" videos factored considerably in our decision to buy ... they made it look so easy! And surprise! It really -WAS- that easy. We used standard block-type ramps (the kind you can buy for $40 ) to get the SUV up off the ground high enough to get underneath to do the work. Everything came off as easy as it was showed in the videos. Other than the fact this bar is a heavy so we had our teen daughter help hold it steady while we bolted it into place (i.e., get help for when you go to lift it), it went super smooth. Thanks for saving us $280 over the cost the car dealer quoted us! P.S. - be sure to watch the linked videos so you get the right trailer lighting attachment and ball hitch for your new hitch.

We are very happy with our trailer hitch, and all the accoutrements that we purchased with it. Your videos were enormously helpful, the hitch went on easily with a bit of help from our teenage daughter to lift it up into place, and we recommend your business to friends when they express an interest in getting a camper.

Quality is good enough; needed the larger diameter shank to fit an aluminum hitch I bought for my UTV. I'd buy it again if I needed it again, but don't see that happening...


Good quality, works great.


The ball is perfect fit for 1-1/4 receiver hole. A couple of taps to the top of the ball to get it fully seated and yiur ready to torque the nut down. If your looking for a heavy duty ball, this is rated at 10k lbs and should do the job. I was impressed with not only fulfillment but also the speed of shipment and the price was unbeatable! Customer service was also top notch taking time to contact me throughout the order and shipping process. No doubt this will serve my purpose of hauling around my trailer used for cars, tractors, motorcycles and other miscellaneous project items. I've included a couple pictures so you can get an idea of how heavy duty this ball is built.
Great buying experience all the way around.


You need to learn how to package things better . Box was falling apart and completely broke when i picked it up only reason not 5 stars. Couldve also been ups's fault as well. But everything was there and shipped and arrived very fast .


It is just what I needed for my hitch fits perfectly. I have been buying all my trailer needs for many years from etrailer have never been disappointed with any purchase.


Great trailer ball for my use on 1985 Casitas trailer, weighing about 1300lbs.
WhIle I got a shank diameter about 1/8" small, I filled space with silicone caulking to deter movement, and applied two lockwashers.
Great price!


My shipping was upgraded without asking and all my products were delivered very timely. They fit my truck perfectly and worked without any trouble. I am very impressed with the products and especially the customer service. I will definitely use again when I have needs for my truck.


Solid ! Needed a heavier capacity 2" ball - This meets the need.


It is heavy duty and works great! Thank s!!!


I found the 1 1/4" hole in my hitch a bit uncommon for a 2" ball but you had the exact product I needed. It fit the hole perfectly & I'm happy with it.


Exactly what I wanted. Well made

  • Curt Hitch Ball # A-90 Recommendation
    The Curt Hitch Ball # A-90 should work very well for you. It has the right ball diameter, weight capacity, shank diameter and enough shank length to install on your ball mount. The # A-90 has a shank length of 2-5/8 inches and your ball mount platform has a thickness of 1-9/16 inches which gives you a little more than an inch for the nut to secure to, which would be plenty. I measured the height of the nut that comes with the # A-90 and found that it is 1 inch thick and the washer is...

  • Is it Okay if Hitch Ball on Tow Vehicle Bumper is a Couple of Inches Higher Than Trailer Coupler
    Ideally, you will want both your tow vehicle and boat trailer to be as level as possible when towing. Some of this will depend a bit on the tongue weight of the trailer you will be pulling. For example, a trailer with a heavy tongue weight may actually lower the bumper on your vehicle enough when attached to reduce the difference in height you referenced in your question. I have attached an article on ball mounts and about halfway down the page it goes into detail on how and why a trailer...

It is interesting that a 1 inch shank diameter ball # 40038 has a 12k capacity yet has a smaller shank, but the reality is the 1-1/4 inch shank diameter is much rarer than the 1 inch shank so there is just more demand for options in that size.

For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball # 19286. Most likely it's a 2-5/16 though.

If this is the case the best option I could make would be to replace the entire assembly with a light from the link I attached.
