Features to know about

Reduces Trailer Sway: Built-In Bracket for Friction Sway Control

Side-to-side movement makes towing stressful, especially on open highways or windy days. This mount includes a built-in bracket that makes it easy to install a friction sway control system. Once paired with a sway control kit, the setup helps your trailer stay in line behind you for better stability and safer handling.

Keeps Your Trailer Level: 3/4" Rise or 2" Drop

Getting the coupler height right keeps your trailer tracking straight and balanced. This mount gives you both a 3/4" rise and a 2" drop so you can match your trailer to your hitch height for level towing. The design helps prevent uneven loading and the sway that comes with it, giving you smoother, more confident tows every time.

Handles Heavy Loads: 7,500 lbs GTW and 750 lbs Tongue Weight

When you’re pulling equipment, campers, or boats, strength and stability matter most. Rated for 7,500 lbs gross towing weight and 750 lbs tongue weight, this solid steel mount takes on serious loads without flexing or fatigue. The hollow shank fits standard 2" x 2" receivers for dependable everyday hauling.

Built to Last: CNC-Machined Steel with Gloss Black Powder Coat

A ball mount takes the brunt of road grime, salt, and weather every trip out. This one’s made from sturdy CNC-machined steel for consistent strength and finished with a black gloss powder coat that resists corrosion. The 7-stage washing process before coating ensures a clean surface so the finish stays smooth and durable over time.

Straightforward Setup: Fixed Design That’s Ready to Tow

No complicated adjustments or extra parts to fuss with—just slide the shank into your hitch receiver, secure it with your pin and clip or lock (sold separately), add your hitch ball, and you’re ready to hook up. The fixed design keeps things simple and solid so your connection stays tight and quiet mile after mile.

Sturdy steel ball mount with hollow shank measures 7-1/2" from center of hitch pin hole to center of ball hole. Built-in bracket lets you mount a sway control ball for simple installation of a friction sway control system.

Great product. Use this with sway bar rather than heavy hitch with load leveler attachments. I don't need levelers with my ultra lite camper. Super quick to ship!!



by:

The Curt ball mount with sway control bracket appears to be a great quality product. It will not be used until May of 2015 when we pick up our new travel trailer. I am sure it will get the job done.



by:

Used this hitch connected to pop-up trailer with single anti-sway bar. Works great, no trailer sway in high winds or 75 mph.



by:

Product works great for me. Fastest shipping I've encountered.

It still is working well. Thanks for asking.



by:

Works great so far, I had some difficulty mounting the ball plate on trailer frame. Make sure to mark holes with a punch and use a new drill bit.



by:

Meriah also found this ball mount (with sway control plate) that is also rated at 7500lbs to match my class 5 hitch rating - this ball mount simplified attaching sway control from trailer frame



by:

This hitch has worked great for the Curt friction sway control for my pop-up camper. I tow with a Honda Ridgeline and this fits perfect and works as it should. I would recommend this to others.



by:

It was delivered quickly. The price was excellent. I've owned this product before and it was stolen off my truck. I use it to pull a ultra lite 21foot trailer. The hitch and stabilizer bar work well together. I really like this product.



by:

Was just what I was looking for.



by:

installing parts together very easy.

Very simple & strong! It’ll work perfect for my new 20’ trailer with sway bar! Love it!

It worked okay, but ultimately I had to go another direction.



by:

This process simply could not have been simpler. It shipped the same day I ordered it and it was in my mailbox a day and a half later The video instructions as well as the print instructions were clear and concise and easy to follow. Both products were quality items, what you'd expect fro etrailer.com, and I would highly recommend this site for quick shipments and high quality products.

Still working hard and performing well. Im very pleased with this purchase. Thanks for the follow-up.

This is the package that I received and I was very disappointed in the condition that I received it . But the unit it self was quiet nice and looks like it will work very fine for my use !



by:

Excellent Item! Will buy again.



by:

We have looked for this tow hitch with sway bar ball, then we saw yours. It fit perfect. Will work great with towing our 13 foot camping trailer. I am a happy customer , And for your quick service, that was great. Thank you.

made a 4500 mile trip this summer worked great no prolbems at all



by:

I ordered and received the ball mount and sway bar together. They were received very promptly and in excellent shape. They are very heavy, i.e., heavy duty. The bracket that was fitted to the trailer was about half a screw wider than optimal size for my smallish trailer but did fit. Installation was easy. The self-tapping screws functioned well. All-in-all, a 10 out of 10 experience.

Great. No problems after a year.

Purchased this hitch as a companion for our Reese anti sway control. The small ball for the Reese sway control fits in the bracket and the 2” drop on the hitch is exactly what we needed to have our Jayco camper level when towing.

Continues to work perfect in conjunction with my Reese friction sway control



by:

Love this hitch. I can travel using a swaybar without having to try to handle a heavy hitch!



by:

Lightning fast shipping, arrived packaged well and was exactly as described.



by:

All went as well as could be expected.



by:

My wife is a member of "Sisters On The Fly" with four vintage trailers, so I have been a frequent customer of etrailer. I have never failed to get excellent customer service and top of the line products.



by:

My first hitch with a small ball for a sway control bar. it does what it is supposed to do and etrailer ships promptly.



by:

It’s a well made hitch ball/anti-sway unit, but it would be even better if it was offered on a flat hitch set up rather than rise/drop hitch only, Is there a technical reason for that flat style isn’t offered? My trailer came with the trailer tongue anti-sway ball mount on the driver side. That leaves me a rise hitch only. Not ideal for all conditions.



by:

I cannot use this ball mount because the shaft is too short that goes into hitch receiver on my one ton Dodge truck. It does not allow enough room between truck back bumper and ball to allow any trailer tongue to be put on ball.

COULD NOT USE THE ITEM!!!!!!!

Hubby is very happy with the hitch. It is being used to attach to an anti sway bar on an F250 to a 20 foot camper. It was easy to install and came very quickly.

See what our Experts say about this CURT Trailer Hitch Ball Mount

  • Will the Curt Friction Sway Control Work w/out a Weight Distribution System?
    Yes, it will Clinton. The Curt Friction Sway Control for Weight Distribution Systems item # 17200 uses a telescoping inner bar with friction pads to fight trailer sway. You can adjust the tension with the easily accessible handle. You will need a ball mount like the Curt Ball Mount w/ Sway Control Tab for 2" Hitches item # D320 to attach the Curt Friction Sway Control item # 17200. What kind of trailer do you have and what is your tow vehicle's year, make, and model? You can add this...

  • Availability of Curt RockerBall Ball Mount w/ Sway Control Tab
    Hey Vince, welcome back! Curt still has not put together a version of the # C45WR with a 2" ball. The only way to make this happen right now would be to order the Curt Ball Mount w/ Sway Control Tab # D320 and then add the Curt RockerBall Shock Absorbing 2" Hitch Ball # CU46FR. One of the side tabs hanging down on the RockerBall will have to be removed so it can fit properly on the ball mount with the sway control tab.

  • Can Volkswagen Touareg Use Weight Distribution When Towing
    You will need to check your owners manual to see what the trailer towing capacity is for your Touareg. Many times the construction of a vehicle will restrict the amount of weight the vehicle can tow. I looked at a 2010 Touareg and the trailer hitch we have that is designed for the 2010 is the Curt Trailer Hitch, part # 13220. This is a Class lll hitch and it has a 2 inch receiver opening. A technical note states that you cannot use weight distribution with this hitch. You will want...

  • Is a Weight Distribution Hitch System Required When Towing a Airstream Trailer Weighing 4,300LBS?
    A weight distribution hitch is not required for towing any trailer but they do make it safer. I personally have never liked the round bar style hitches like Husky makes and always recommend units like the Fastway e2 # FA92-00-0800 since it uses a straight bar. These do not hang down a low as the round bar systems so they will not drag going over speed bumps or when you hit pot holes. As long as you are staying within your towing capabilities and your Tacoma is not overly sagging from...

  • Volvo XC90 Incompatible with a Weight Distribution System
    Using a weight distribution hitch with your Volvo XC90 would be strongly discouraged. Weight distribution hitches redistribute some of the load from the rear axle of the tow vehicle to the front axle, that force has to be transferred either through the vehicle's frame (for a body on frame vehicle) or its unibody (for the XC90). Weight distribution hitches are used for hauling heavier trailers your Volvo is not considered a heavy duty hauler and has a maximum speed of 50 mph while towing. An...

  • Options for Sway Control Tab for Ball Mount for Attaching Hitch Ball
    Sounds like you are looking for the mount for the small ball of your friction sway control unit. You have a couple options like the part # D320 which is a ball mount that has the mounting tab attached to the side of the ball mount platform. We have the # 3442 which allows you to weld a tab onto your current ball mount, or we have the # RP26003 which fits between the ball mount platform and the hitch ball.

  • How Does a Second Friction Sway Control Unit Get Installed on a Trailer
    You are correct, adding a second sway control bar, like the Curt Friction Style Sway Control, # 17200, is recommended for trailers over 26 feet long. You will need to use the weld-on friction sway control tab # C45822 or # 3442. It will get welded to the side of the ball mount. Welding should be performed by a qualified professional welder. Once welded on it will look like ball mount # D320 except the tab will be welded to the other side (since the plate you are using is occupying...

    Hi Joshua! I do have a couple potential option for you, but we do not have any ball mounts with no drop or rise that will work for this purpose. With that said, you could go with one of the two options below: Option 1: Curt Ball Mount w/ Sway Control Tab for 2" Hitches - 3/4" Rise, 2" Drop - 7,500 lbs # D320 Curt 2" Hitch Ball - 2" Rise - 1" Diameter x 2-1/8" Long Shank - 6,000 lbs # C40034 Option 2: Curt Ball Mount 3/4" Rise or 2" Drop - 12-5/8" Long # D-26 Reese Sway-Control Bracket...

  • Where to Measure to Determine Correct Rise/Drop for Ball Mount
    Since there aren't any zero rise/drop ball mount options (shockingly) you might verify that your setup was measured in the right spots. You'd want to measure from the bottom of the coupler lip down to the ground when the trailer is level and then from the top of your hitch opening down to the ground. The part # D320 has a drop of 2 inches and comes with the tab needed for friction sway control. This probably would be close enough to what you'd need.

  • Adjustable Ball Mount With Sway Control Tab
    You can pick up a ball mount like the Curt # D320 with a sway control tab that offers 4 inches of drop right here on this page! The Draw-Tite # 7390 is adjustable between 3-3/4" of rise and 5-1/4" of drop and has a 6,000 lb towing capacity and 600 lb tongue weight capacity. Your other option is to use a ball mount with a 4" drop and 7,500 lb capacity such as the Draw-Tite # 2753 with Reese Sway-Control Bracket # RP26003.

  • Is There A 4" Drop Or Rise Ball Mount With A Sway Control Tab?
    Hi Tim! I do have a couple options for you, but Curt currently does not offer the Ball Mount w/ Sway Control Tab # D320 with a 4" drop or rise. I couldn't find one from other manufacturers either. What you will need to use is either the # 3442 and have it welded on, or use the Reese Sway-Control Bracket for 2" Ball Mounts # RP26003 (which is what I would do as it is a lot easier). Either of these could then be paired with the Curt Dual Length Ball Mount for 2" Hitches - 4-1/2" Rise, 5-3/4"...

  • Recommended Ball Mount W/ 5" of Rise for a Volvo XC90
    Rebekah, so unfortunately the Curt RockerBall # C40047 won't physically fit on your Curt Rebellion XD # C83WR so the two can't be used together. What you could do instead is, use the Curt Ball Mount for 2" Hitches # C45336 instead which will work with the Rockerball and has that 5" of rise you're looking for and then get the Replacement Sway Control Tab for Weight Distribution System # 3442 welded on so you can use a weight distribution system.

  • How Does the Reese Friction Sway Control Kit Attach to the Hitch?
    Hey Larry! The Reese Friction Sway Control Kit item # 83660 attaches to ball mounts like item # D320. There's no welding. We have a couple of other options like the Sway Control 2-Ball Platform for BulletProof Hitches Ball Mount item # 358SWAYCONTROLBALL. However, these are all specific to the manufacturer of the ball mount. If you want me to look and see if we have any options for your ball mount I would just need you to comment below with a part number.

  • Help With Trailer Sway Pulling a 13' Travel Trailer Weighing 2,300LBS Behind a Full Size Truck
    While a weight distribution hitch like the Fastway e2 # FA92-00-0450 will perform better to control trailer sway you could also use a Friction Sway # 17200 with a Ball Mount # D320. If you go this route you have to remove the sway bar before maneuvering the camper or driving on twisty roads.

  • Effect of Using Extra-Long Ball Mount for Towing
    Use of an extra-long ball mount like # 80232 will not reduce a hitch's towing weight capacity the way that use of a separate extender/adapter will. Extenders like # C45791 and # D-192 actually do reduce the hitch towing capacity by 50-percent. Weight distribution hitch systems such as # C17501 should not be used with any type of hitch extender or adapter. A friction sway control unit like # 83660 can be used with an extra-long ball mount like # 80232 by adding a sway control bracket like...

    Hey Bryce, You can use weight distribution on a 2024 Toyota Grand Highlander so long as the hitch is rated for use with weight distribution, so the frame isn't an issue. For the '24 Grand Highlander you would be able to use weight distribution with only one hitch that fits, the Draw-Tite Max-Frame Trailer Hitch Receiver # DT95PR. The other hitch that fits, the Curt Trailer Hitch Receiver # C26VV is not rated for use with weight distribution, but you could still add sway control by using...

  • How To Mount Two Friction Sway Control Bars On a Ball Mount
    In order to use two friction sway control bars like the Reese Friction Sway Control Kit part # 83660 you'd need to have two of the friction sway control tabs like the Weld-On Sway Control Tab part # C45822 welded to the ball mount. The other options would be to use the Curt Ball Mount part # D320 assuming it has the correct rise/drop for you needs and only have one friction sway control tab welded on.

  • Will Curt RockerBall Fit Curt Ball Mount w/ Sway Control Tab for 2" Hitches
    The anti-swivel base on the # C45WR is missing a tab on one side to make it compatible with the sway control tab. This does not adversely impact the performance. You can use the # C40047 with the # D320 but you would have to bend or cut one of the tabs off of the anti-swivel base to make it fit since it is not available without the tab for the 2" ball.

    Thank you for pointing out this error, I was able to verify with the owners manual for your 2019 Audi Q7 you should never use a weight distribution hitch and removed the old question. The best way for you to help reduce/prevent sway is by using a Tuson Asymmetric Sway Control # 335TSC-1000. This will require your trailer to have electric brakes as it uses the brakes independently to prevent sway from occurring.

    The # 3442 replacement sway control tab would be welded onto the side of a ball mount, and the 1-1/4 inch diameter trailer ball would mount in the 5/8 inch diameter hole in the tab. If a ball mount with a 3/4 inch rise or a 2 inch drop would work, Curt offers the # D320 with the tab already welded in place.

  • Sway Control Recommendation For A Toyota Tacoma Towing A Pop-Up Trailer
    The ball you're referencing on your trailer tongue is most likely the one that would come with a friction sway control bar like the Curt Friction Sway Control for Weight Distribution Systems # 17200. I'm assuming you most likely don't experience a lot of sag since you're towing a pop-up so a simply friction sway control bar would most likely be the solution you need without overdoing it. The # 17200 comes with the tab to weld onto your ball mount for the sway control to connect to but...

    For the Curt Friction Sway Control for Weight Distribution Systems # 17200 you will remove the inner arm and spin it 180 degrees, then reinsert into the friction sleeve. This will allow the sway control to be used on the drivers side of your travel trailer. The kit will include a weld on tab for your standard draw bar. It would end up looking similar to Curt Ball Mount w/ Sway Control Tab # D320 with the way the sway tab is welded onto the side of the receiver draw bar. Yours would be...

  • Is There A Torque Spec For Trailer Sway Control Hitch Ball
    I called my contact at Curt and asked about the torque needed for the ball that the sway control is attached to on the trailer hitch. They told me that there has never been a torque listed but if you would torque it to about 150 ft-lbs it will have no problems. There is no torque value in the installation instructions. You want to periodically check all of the towing components to make sure they are all secure and ready to use.
