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 etrailer.com 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 etrailer.com. 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.

by:

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.


Comments
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.

Great add to my overall towing solution for my boat.
This 2" Hitch Ball - 1-1/4" Diameter x 2-5/8" Long Shank - Chrome - 10,000k unit is an amazing and will last for years.



by:

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



by:

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



by:

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.



by:

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.



by:

Etrailer has great product. Good deals and quick shipping. My only concern is the use of UPS surepost. UPS Sure post always seem to add 2 days to normal delivery times this time however UPS made an error and delivered it to the house so I received the item 2 days early. Thank you etrailer.

It's a trailer ball.

Its still a trailer ball, works as it should. Good company.

I ordered 15 of this item and the package was missing 1pc. I immediately contacted the customer service and they shipped me one within a week. Very responsive and helpful customer service. Thank you!



by:

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.



by:

etrailer is extremely great Company to deal with. They have the products and they are delivered when they say. etrailer has videos on how to install your product. Great company.



by:

Great company to do business with and the customer service is great also.



by:

After balking at the cost to have an auto-shop add a trailer to our Toyota Highlander, we found etrailer.com 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.


Comments
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.

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.



by:

Great quality perfect for my trailer.



by:

My experience with this company has been nothing less than stellar! From the moment I searched for the item I needed, to the delivery of my item, and everything in between, my experience has been a very pleasant one! Great ol’-fashion customer service; under-promising and over-delivering; and great follow-up after the sale and after I received my item. I highly recommend this company for future business!



by:

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!



by:

Happy with price and product



by:

Relatively basic installation with correct LARGE torq wrenches for the ball . It doesn’t take long in a nice flat parking lot. I hooked this up to tow a travel trailer on a cross country move 3500miles or so with a good share of dirt roads, Made the ride smoother and safer



by:

zero issues, no corrosion-I don't lube my trailer balls per my preference. I check it frequently for being tight and have yet to adjust it.


Comments
Still no signs of corrosion or wear.
Don B - 06/29/2021

by:

Part of WD hitch system



by:

Items received in good condition and was very impressed about the quality of the hitch, I am a race car builder and fabricator and know what quality is. Kind of disappointed that for the amount of money spent on a complete hitch assy. that you would not throw in a cover for the ball with your printed advertising on it so I guess its the ol' tennis ball cover for us



by:

Hitch ball...does what its suppose to.



by:

I liked the fact that the tag on the ball gave the recommended torque for tightening the nut. 450 ft/lbs



by:

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

Ask the Experts about this CURT Trailer Hitch Ball



  • What is the Size of the Nut on Curt Hitch Ball # A-90
    The nut on the Curt hitch ball # A-90 requires a 1-7/8 inch wrench or socket. The nut fits on the 1-1/4 inch shank of the ball. This ball is designed to fit draw bars that are 1/2 inch to 1 inch thick. It was a capacity of 10,000 pounds.

  • 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...

  • Availability of a 2 Inch Diameter Ball with a 10,000 Pound Capacity
    There are some 10,000 pound capacity balls with a 2 inch diameter but they are part of a Convert-A-Ball Interchangeable ball set. The most popular set is # 901B. It has a 1 inch diameter shank. You will also want to check the capacity of the truck if the ball will be mounted on the bumper. Unless otherwise noted in the owners manual or on the bumper, most bumpers are only rated for 3,500 pounds gross trailer weight. If you have a frame mounted hitch, the capacity will be higher and should...

  • Can a 1-7/8 inch Hitch Ball be Used with a 2 inch Coupler on Trailer
    If your trailer has a 2 inch coupler then you definitely need to go with a 2 inch ball. Even though 1/8 inches doesn't sound like very much, it is enough that your trailer could come uncoupled under the right conditions. I have attached a link to our selection of 2 inch hitch balls for you to filter through. You will just need to be sure that the shank of the hitch ball has the correct diameter and that it is long enough for your ball mount. For example, the popular Curt 2 inch Hitch...

  • What is the Torque Requirement for Curt 2 Inch Hitch Ball A-90/40090

  • 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...

  • Torque Specifications For A 2 Tow Ball Nut Towing A 700lb Drift Boat
    The 2" Hitch Ball like the # A-90 requires a foot pound torque of 450 but I would really need to know your specific ball to tell you the torque rating. An impact wrench is the preferred installation method but if you don't have access to that, you can also torque down with a 1-7/8" wrench or socket. After inserting the ball mount in your receiver sideways you can torque it down as tight as you possibly can. Included is a video resource for this hitch ball example. I hope you have a...

    If your trailer has come off of your 2 inch trailer ball one of two things are happening.

  • Why Do CURT Trailer Hitch Balls 40038 and A-90 have Such Different Towing Capacities
    I spoke with my contact at CURT and he told me what gives the CURT Hitch Ball, # 40038, more strength is the way it is threaded and that it is heat treated beyond what # A-90 is so that gives the 40038 the higher rating. He added that even though 40038 has a smaller shank, the way that the metal was finished allowed it to be tested and rated higher.

  • 2-5/16 inch Hitch Ball Recommendation for Reese Weight Distribution System

  • Highest Capacity 2 inch Hitch Ball with 1 inch Diameter Shank
    The highest capacity 2 inch hitch ball we offer that has a 1-1/4 inch diameter shank is going to be the Curt # A-90 which has a 10k capacity. 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.

  • Do 5,000 lb Trailers All Use the Same Hitch Ball Size
    That's going to depend on the coupler of the trailer. I can't gaurantee you what size you will encounter so you will need to check with the owner of the trailer currently and ask what it takes. 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.

  • How to Determine Correct Ball Mount for Tow Vehicle and Trailer.
    In order to choose the correct ball mount for your tow vehicle and trailer, you will first need to take a couple of measurements. With your tow vehicle parked on level ground, take a measurement from the ground to the top of the trailer hitch receiver. Then with your trailer on level ground, measure from the ground to the bottom of the coupler. If the hitch height on your vehicle is greater, you will want to find a ball mount with a drop. If the coupler height is greater, you will want...

    The highest capacity 2 inch hitch ball we have that has a 1-1/4 inch shank diameter is the Curt hitch ball part # A-90. For a 12k capacity with a 1-1/4 inch shank you'd need a 2-5/16 inch ball like the part # 19286.

  • Solution for Older Trailer with Broken Taillight Lens
    Easiest solution would be to replace your entire light assembly as I would have to see a picture of the light/lens to see if we have it. Based on your description I would have no idea on whether or not we carry it. Due to the age of your trailer I would suspect we do not carry the lens if it was original equipment. 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.

Tongue weight is the tongue weight of the ready-to-tow trailer with boat added to the weight of any cargo you are carrying behind the rear axle on the tow vehicle.
