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!!!!!!!



by:

I purchased this for use with a friction anti sway device I installed on an enclosed V nose trailer. It worked well.



by:

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

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

My new hitch is working out great especially with the sway bar ball mount. So you dont have to get one welded onto your new hitch!



by:

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!



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:

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.



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:

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:

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:

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.

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:

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:

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



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:

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:

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



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:

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



by:

product works great pulling my camper. leveled load anti sway bar attached perfect



by:

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:

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.



by:

Item was as described and shipped very fast. I have not towed with it yet but see no problem. The shank (insert) part seemed slightly short to me. It was shorter that others I have. My trailer has an electric lift and I was concerned it might not clear the lift gate on the Jeep if it was too close. Worked out perfect though. Just something to thing about next time.

  • 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.

  • Availability Of a Ball Mount With Friction Sway Control Tab Rated For 10,000LBS
    You do have a couple options but the Curt Ball Mount w/ Sway Control Tab # D320 is not available in a 10K weight capacity. You can use the similar Curt Ball Mount # C45310 rated for 10,000lbs and weld on a Sway Control Tab # C45822. We do also have the Bolt On Bracket # RP26003 but his has a 1" hole versus the 1-1/4" hole on the ball mount. So you will either need to drill the hole larger or use a 2-5/16" Ball # C40007 and Reducer Bushing # F-2. Then you will be able to mount the Friction...

  • 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...

  • Weight Distribution Compatibility with a 2005 Nissan Murano Class III Trailer Hitch
    If your 2005 Nissan Murano came with a factory installed Class III trailer hitch, then your owners manual should tell you if a weight distribution system can be used or not. I can tell you that a weight distribution system cannot be used with any of the Class III trailer hitches that we offer for your vehicle. Your travel trailer is fairly light, but if your vehicle sags a lot when towing your trailer, then you could look into the Firestone Coil-Rite Air Helper Springs, # F4118. These...

  • Hitch Ball Hole To Sway Control Ball Hole Distance For The Curt Sway Control Ball Mount # D320
    Hi David, The sway control ball hole of the Curt Ball Mount w/ Sway Control Tab for 2" Hitches # D320 sits approximately 3/8" back from the hitch ball hole (from center to center). The instructions for the Reese # RP26003 do not apply to the Curt # D320 so you wouldn't need to follow those rules with this ball mount.

  • 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.

  • 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.

    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.

  • Can A Weight Distribution Hitch Be Installed On A 2019 Audi Q5?
    I can't recommend a weight distribution hitch for your 2019 Audi Q5 because your vehicle design prohibits it. I can recommend the Draw-Tite # 76183 standard Class-III hitch paired with a Curt # 17200 Sway Bar. The benefit of using a weight distribution hitch is the ability to move some of the tongue weight to your tow vehicle's front axle and to the trailer axle. If you can manually manage the distribution of weight in your trailer safely then you could use a standard hitch with sway...

  • 2 Adjustable Ball Mount with Sway Control Tab
    I may have an option for you but unfortunately, I cannot recommend you weld a sway control tab onto the side of the hitch ball on the Channel Style Adjustable Ballmount part # C45900. Instead, I recommend using the Curt Ball Mount w/ Sway Control Tab for 2" Hitches - 3/4" Rise, 2" Drop - 7,500 lbs # D320. The Draw-Tite Adjustable Ball mount has a 6,000 weight capacity with a maximum rise/drop of 3-3/4" and 5-1/4" respectively. I have attached a review video of this adjustable ball mount...

  • 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.

  • Availability of Curt Ball Mount w/ Sway Control Tab For 2" Hitch

If you're going to use your existing 2" ball make sure it has a 1" diameter shank. This ball mount has a 3/4" rise and 2" drop. See the helpful article below which explains how to measure.

  • 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...

  • Which Sway Control System for a 2004 Trailblazer and 16 Foot Horse Trailer
    One of the most important things you can do to control sway is to get the trailer and vehicle as level as possible, once this is done, then it is time to look into a sway control system. Since it is a 16 foot trailer and you are only carrying 1 horse, I assume there is not a lot of weight, so a small friction sway control system should be sufficient. The Friction Sway Control system, part # 17200, should do fine. Our installation services are offered at our Distribution Facility in Wentzville,...

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.

  • 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.

    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. If you have a smaller trailer which does not have electric brakes the Friction...
