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.


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.

The ball mount was a complete failure even after a lengthy discussion on the phone. I wanted a ball mount that would accept the rocker ball and anti-sway bar. The bar sent to me can't be used this way. An email and phone message to the sales person I ordered with, got no response.

I am sorry the parts didnt work out like you were hoping. I will have our customer service team reach out to you about this quickly!


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


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.


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.


Very prompt service and delivery. Ready to get this on the truck and start pulling the new camper!


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.


Was exactly what I needed, for a great price, with clear installation instructions.


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.

Pat W.


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


Works well. Much better than the previous two piece unit. No play between the two parts, so no clunking.


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 !


Have not yet used it as I just got to install the hitch today.


Great product


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


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.


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, 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.


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

Dean E.


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


installing parts together very easy.


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.


Fast shipping


Worked wonders with the small toyhaler camper I have went into the mountains and even had a blowout on the haler with the sway control tab held up great


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!!


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


I haven't actually put this product to use, yet, but it seems to be very well made with clean strong welds. Nice and heavy, and arrived looking like it was just made. And it's made in the USA!!! No Chinese steel. This will work perfectly with my sway control bar and hitch.


This ball mount fits a sway bar that was delivered with my Casita travel trailer. It is exactly what I need. The price was very reasonable and the delivery time was very short. I have purchased other products from this source and found them to be very reliable.

  • Length of Curt Sway Control Ball Mount part # D320
    The distance from the ball hole of the Curt sway control ball mount part # D320 to the pin hole is 7-1/2 inches. I don't see any reason why the length would be an issue with a 2013 Chevy Silverado 1500 using the bumper hitch.

  • How to Pick Out the Right Rise/Drop Ball Mount
    In order to pick out the correct rise/drop ball mount you need to take a couple measurements and do one simple calculation. It sounds like you may need a different drop ball mount, but to prevent you from ordering the wrong one check out the FAQ article I attached that details how to select the correct height ball mount for your setup.

  • Sway Control Bracket on Both Sides of a Ball Mount
    I am sorry, but the Curt Ball Mount with Sway Control Bracket, part # D320, is only offered with the sway control bracket on the right side. We do offer a Sway Control Tab, part # 3442, that you can weld onto a ball mount. Or, we also offer a Sway Control Adapter, Left Side, part # 3475, that can be used with a Round Bar weight distribution head.

  • Do The Self Tapping Screws For The Curt Friction Sway Control Bar Need To Be Torqued Down
    Self tapping screws like the ones used in the Curt Friction Sway Control for Weight Distribution Systems # 17200 aren't meant to be torqued down. Simply drilling them into the frame until they pull the bracket tight against the frame is all you'll need to do.

  • Sway Control Bracket Recommendation for a Left Hand Sway Bar
    You can use the Curt Ball Mount with Sway Control Bracket, # D320, in the rise position to have the sway control bracket on the left side, but you will want to remember that doing this will raise the height of your trailer tongue by almost 3 inches. This can create additional sway issues even with a sway control bar installed. Another option that you can look into is using a weld on sway control tab like part # 3442. This tab can be welded to the side of your current ball mount to provide...

  • How Many Curt Friction Sway Control Units for Use with R-Pod 179 Camper Trailer
    Due to the length of your R-Pod 179 you would only need one of the Curt Friction Sway Control Units part # 17200. For a ball mount that has a mounting tab for the ball of the # 17200 the part # D320 would work great.

  • How is Draw-Tite 3442 Sway Control Tab Attached to Ball Mount
    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 Unit Recommendation for T@G Tear Camper Trailer
    The Pro Series friction sway control unit part # 83660 that you referenced would be what I would go with if I were you. It is essentially the same thing as the other units and is at a much better price. Your trailer is pretty lightweight, but if you are getting any sway when semi trucks pass you or in strong winds this unit will help greatly. I attached an install video for more info for you to check out as well. With this you'll need a ball mount with a mounting tab for the sway bar...

  • Can a Friction Sway Control Bar be Used with a 3-Ball Ball Mount
    You will not be able to use a friction sway bar such as # 83660 with a tri-ball ball mount. There would be no place to attach the sway bar to the vehicle side and you would not be able to use a bracket or weld-on tab for the small ball the sway bar needs. A ball mount such as # D320 would be what you need. I have linked a video review of it for you.

  • 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.

  • Does Trailer Hitch Ball And Sway Control Ball Need To Be Level
    The Curt Friction Sway Control, part # 17200 has a mounting plate for the trailer that can be moved either up or down to let you install the sway control unit level. I called my contact at Curt and they told me that installing the unit and having a 1 inch difference will not affect the performance and will work just fine. You do not want to increase the friction setting too much or you could have problems. You always want to adjust the tension by 1/4 turns. You should always remember...

  • Ball Mount With Sway-Control Tab
    There is also a fixed ball mount that already has a sway control tab on it, the Curt Ball Mount w/ Sway Control Tab for 2" Hitches # D320. This ball mount has a 7,500 lb towing capacity, 750 lb tongue weight capacity and 2" drop or 3/4" rise.

  • Towing with the BM20 extra long shank ball mount
    There are many factors that go into determining a weight rating for a ball mount. The Bropy Ball Mount # BM20 for instance with having the extra long 13-1/4" ball mount to center pin hole will create more leverage on the receiver tube. The same way you use longer ratchets to make turning a bolt easier. That is one factor that a manufacturer has to consider when developing a ball mount. When towing your pop up you will not likely notice a difference in the way the trailer tows. This is...

  • Ball Mount that has Sway Control Bracket Attached to It
    We don't have a wider bracket than the # RP26005 for your ball mount so the best option we would have would be a new ball mount that has the bracket already attached like the Curt # D320 which has a drop of 2 inches since you aren't wanting to do any welding.

  • What Ball Mounts Work with the Reese Sway-Control Bracket for 2" Ball Mounts RP26003
    The Reese Sway-Control Bracket for 2" Ball Mounts part # RP26003 works with any ball mount that has a platform narrower than 2-5/8 and with a 1" diameter hitch ball hole. The adapter is also 3/8" thick so you need to be sure your hitch ball has some additional shank to accommodate this. Unfortunately, we don't carry the ball mount you said you have so I won't be able to obtain these dimensions for you to confirm compatibility, you will need to do this yourself. If your ball mount is not...

  • Using a Weight Distribution Hitch on a 2012 Kia Sorento V6
    The Draw-Tite Max-Frame Trailer Hitch Receiver # 75684 that fits your 2012 Kia Sorento has the weight distribution rating on the hitch as Draw-Tite has tested the hitch to a weight distribution rating but they do not rate the vehicle. I did see in the owners manual that while they don't say it can or can't be used with weight distribution they did refer to using a sway control with the vehicle. For that reason I would recommend not using a weight distribution system for your Sorento....

  • Will Sway Control Tab Hit Trailer Frame With Tight Turns
    The sway control tab on the Curt Ball Mount w/ Sway Control Tab for 2" Hitches # D320 you referenced won't hit the trailer frame with sharp turns. The tab is attached to the side of the ball mount and the trailer would need to be nearly sideways to hit the tab. Friction sway controls should be removed if you're backing at an angle where jackknifing may occur. Sway control brackets that are integrated in the ball mount like the Curt # D320, or sway control brackets that bolt to a ball mount...

  • 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...

  • Friction Sway Control For 11 Foot Northwest Coach Lil' Dipper Camper
    The Reese Friction Sway Control kit you asked about, part # 83660 would work great with your small camper, and any camper up to 25 feet in length. You'd also need a ball mount with a sway control tab on it for mounting the ball that would connect the sway control unit to the ball mount. The Curt # D320 can be used in the rise or drop orientation, and will provide either a 3/4 inch rise or a 2 inch drop. If that isn't sufficient, there's an adjustable ball mount available part # 7390 which...

  • Curt Left Hand Sway Control For Travel Trailer
    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...

    If your trailer has a weight distribution hitch and you are using a weight distribution head, you will not need any other parts to install the Reese Friction Sway Control Kit, # 83660. The sway control ball will install in the small hole on either the right or left side of the trailer, normally the right side.

  • Bracket Recommendation for Installing Second Curt Friction Sway Control
    For installing a two friction sway controls like part # 17200 you would need to have a second tab welded to the side of the ball mount. For that you would want the part # C45822. For a ball mount that has one tab installed on it already you would want the part # D320. This ball mount has a drop of 2 inches.
