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.

Ask the Experts about this Curt Trailer Hitch Ball

  • How to Choose the Correct Hitch Ball Size
    A 2" hitch ball like part # A-90 is pretty standard but you really need to know what size hitch ball your coupler is compatible with. It should be stamped on the trailer coupler itself. If you already have a ball mount then you need to make sure that the shank of your hitch ball is compatible with that as well. The # A-90 has a shank with a 1-1/4" diameter and is 2-5/8" long. For people who will be towing different sized trailers it is a lot easier to have multiple hitch ball options....

  • Torque Rating for Nut of Hitch Ball part # A-90
    The correct torque for installing hitch ball # A-90 is 450-ft-lbs. You will need either a torque wrench.

  • 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.

  • 2 Inch Hitch Ball with a 1-1/4 Inch Diameter Shank
    The HL17256 is no longer a product we carry but a hitch ball with a 1-1/4 inch shank, like the Curt # A-90, fits into it. I've linked all the hitch balls we carry that will work for you.

  • Will Curt 2 Inch Ball # A-90 Fit Reese Weight Distribution System
    Yes, you can use 2 inch ball # A-90 with Reese weight distribution system # RP66541. In fact, that is the 2 inch ball we have listed on the weight distribution system's product page in the related parts on the right side of the page.

  • Length of Shank on Curt 2 Inch Trailer Ball Part # A-90
    The 2 Inch Diameter Ball with Medium Shank, part # A-90 would be the correct ball to use with your Reese SC weight distribution system. The total length of the shank is 2-5/8 inches, while the length of the threaded portion is 2-1/4.

  • Curt Hitch Ball Torque Specs for Installation
    The 2" Hitch Ball # A-90 requires a foot pound torque of 450. I've attached a diagram showing the Torques Specs for Curt hitch balls to assist. The trailer ball needs to be tightened to a certain torque specification in order to prevent the nut from vibrating loose, so for safety you need to make sure your hitch ball is securely mounted to your ball mount or bumper.

  • 2-5/16 inch Hitch Ball Recommendation for Reese Weight Distribution System
    For a 2-5/16 inch ball to use with your Reese SC WD system the part # 19286 would be a great option. This is the 2-5/16 inch ball we recommend the most with Reese weight distribution systems.

    We do have a 2 inch diameter hitch ball with a 1-1/4 inch shank that may work well for you. It is the Curt Hitch Ball, part # A-90. This hitch ball has a shank length of 2-5/8 inches and has a gross towing weight capacity of 10,000 lbs. I have attached a product review video you can check out.

  • 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...

  • 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.

  • Troubleshooting a Trailer that Keeps Separating from Tow Vehicle
    If your trailer has come off of your 2 inch trailer ball one of two things are happening. Either the coupler of your trailer is designed for a 2-5/16 inch ball or the latch of your coupler isn't functioning. For a 2-5/16 inch ball check out the link I attached. You will need to know the diameter of the hole in your ball mount to pick out the correct ball. We offer several repair kits for trailer couplers as well that could work. Without knowing what coupler you have it would be hard...

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

  • 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...

  • 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.

  • Recommended 2-Inch Hitch Ball for Curt Weight Distribution System C17051
    The Curt Weight Distribution System # C17051 requires a hitch ball with a 1-1/4-inch diameter shank. Part # 40038 is the recommended 2-inch ball; it has a higher capacity than # A-90 that you referenced and actually costs less.

  • Weight Distribution for a 2010 Toyota Tundra and 6700 Pound Fleetwood Travel Trailer
    When choosing a weight distribution system you will need to go by the total tongue weight. This is calculated by taking the tongue weight of the trailer when loaded and ready to tow and then adding to that the weight of any cargo loaded behind the rear axle of the tow vehicle. Tongue weight is typically 10 to 15 percent of the gross trailer weight. If your trailer weighs 6700 pounds that would make the tongue weight 670 to 1005 pounds. Based on this information alone a system rated for...

  • 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...

  • 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...

    We have a USA made solution but it's not the Curt you mentioned. You might be interested in a Convert-A-Ball Interchangeable Ball Set # 904B. This product is made in the USA and comes with an interchangeable hitch ball that will give you the option to easily change between a 2 inch and a 2-5/16 inch ball.

    If you are looking for a hitch ball with a 1-1/4 inch shank to fit your ball mount, we offer several to choose from.

This durable, chrome ball has a 1-1/4" diameter x 2-5/8" long shank with wrench flats. It has a weight capacity of up to 10,000 lbs and made in the USA.

  • Recommended 2 Inch Hitch Ball and Ball Mount with Drop
    For your trailer coupler and ball mount, I recommend the Curt 2 Inch Hitch Ball # A-90. This 2 inch ball has a 1-1/4 inch diameter shank, so you will just want to make sure that your ball mount has a 1-1/4 inch opening to receive this hitch ball. To most accurately determine the amount of drop you will need on your ball mount when measuring from the ground to the trailer coupler, you will want to measure to the bottom of the coupler instead of the top. With this in mind, the measurement...

  • Weight Distribution Recommendation for Trailer with Loaded Tongue Weight of 700 lb
    The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. If your loaded tongue weight is 700...

    When picking out a weight distribution system it's important to make sure your setup's total tongue weight, which includes the loaded tongue weight of the trailer along with any added cargo weight coming from behind the rear axle of your tow vehicle, falls comfortably within its weight capacity range. If your trailer's loaded tongue weight will be around 400 pounds the Curt TruTrack Weight Distribution System # C17500, which has a tongue weight capacity of 800 to 1,000 pounds, will definitely...

  • Best Weight Distribution With Sway Control for Trailer With 1,100 lbs Total Tongue Weight
    The BlueOx SwayPro # BXW1506 is a good system but I recommend the Reese Strait-Line # RP66130 over it. While both systems will be less noisy than the Equal-i-zer you referred to, the Strait-Line has the advantage because of its sway control system. The SwayPro uses a 4-point sway control system like the Equal-i-zer but the Strait-Line uses a dual cam system to prevent sway. This system's spring bars are suspended by this cam system (see accompanying photo) which ensures that the Strait-Line...
