When a sway control hitch is not an option for your squirelly trailer, use this instead. It ties into your trailer or camper's electric brakes to dampen sway the moment it starts. Works with all major OEM and aftermarket brake controllers.

Quick Tip: If you typically have a lot of sway, take a look at your trailer's load. See if you can spread the weight out better to lower your tongue weight. A lot of times this will improve your ride, but if you still have sway, it'd be a good idea to invest in this device.
You might be used to applying the manual override on your brake controller to control sway. The Tuson sway control does this for you, automatically. It uses a built-in inertia sensor and a computer that continually monitors the angle of your trailer as it tracks behind your truck (the technical term is "yaw"). When your trailer starts to get off track, the module sends a pulsing signal to the brakes on the opposing side that the wind gust is coming from, which nudges your trailer back in line. After 30 minutes of smooth sailing, the unit enters sleep mode. But, just tap on your brakes or apply the manual override, and the unit will wake up and get back to work.
When engineers at Ford, GM, Dodge, and Toyota took the Tuson sway control (TSC) out for a road test, they found that it worked in concert with their built-in brake controllers and sway control systems. In some cases, it even engaged before the vehicle's built-in functions. This shouldn't be a surprise because the TSC is based on the same technology used in automotive vehicle stability systems. So, if you need something that handles great on the trailer side because your truck already has sway control, this will create a super-stable setup.
The TSC also meets the SAE J2664 standard for trailer sway testing. Despite agressive, exaggerated oversteering - more than what the SAE test called for - the trailer veered no more than 7 degrees off track from behind the tow vehicle. And if you own an F-150 or F-250, Ford has also verified that the TSC meets the towing requirements set by SAE J2807.
This device installs permanently, and most people say it takes about 3-5 hours to do so. Tuson's installation manual is quite thorough, so please consult it - or a qualified electrician - when you need to.
The module should be installed on your trailer frame's centerline, parallel to your axles. This is usually a spot on the chassis, 5' to 10' directly behind your coupler. On smaller campers, an ideal spot may be right under the nose of your trailer. On larger 5th wheels, a flat mounting location may be found further back, as shown above.
To achieve independent left- and right-side braking, you're going to have to split your single brake circuit into 2 separate ones. To do this, you need to run 14-gauge wire extensions (sold separately) from the module to the respective sides of your trailer, where they'll be tied into to the wiring on the back of your brake assemblies. After that, connect the Tuson unit to your trailer's 12-volt auxillary battery, breakaway switch, and trailer plug.
Quick Tip: Because this device relies on your auxillary trailer battery to work properly, make sure it is fully charged before leaving on your next trip.
Finally, mount the LED light in a spot where it will be easily visible from your rear view mirror so you can tell right away when the system is working normally, it's in sleep mode, or if there's an issue that requires some troubleshooting.
To make sure the system is installed correctly, just plug in your wiring harness, power up your truck, and apply the manual override on your brake controller to wake up the TSC. The LED status light should be flickering green. If it isn't, check Tuson's installation manual for a step-by-step guide on how to troubleshoot.
Works great! I installed this myself. I'm a 23 year tech and this was an easy job for me but took some time. I would suggest having an experienced tech do your wiring. I used a junction box and sealed all components well. The led light indicates when the system contracts a sway and any problems. I mounted the led box in the center of the front of my camper so I can see it from my rear view mirror. I use airbags on my truck for weight distribution and I have no issues.This system works as advertised. The only problem I had was the wire going to the led has a small plug that is somewhere around three feet from the led. The plug ended up coming apart and the wire drug on the ground my first use. I cut the plug off and wired and shrink wrapped the wires. No more plug to come undone.
Straight forward, clear instructions for installation. Performance is as expected and beneficial. Electronic control activated twice on my last trip and successfully eliminated trailer sway during 2 extreme events. Very happy with the performance and added safety.

Still working as expected. Very happy with this product.
I ordered the product late Saturday afternoon and I received it mid day the following Monday. Very quick delivery. I had it installed today, Tuesday. I haven’t had a chance to try it out but the etrailer price and fast delivery is impressive. I’ve ordered from etrailer for years and I’ve never been disappointed.

I love this product . No more trailer sway. No more white knuckles when getting passed by 18 wheelers No more 50 mph with strong crosswinds.This is the best money I’ve ever spent in in some 50 years of trailer ownership.

Been a great product. Took exactly 4 hrs to install. I installed it on a 22ft Imperial camper that was swaying a lot. After rearranging weight and installing this sway control system the trailer is a dream to pull. I think every camper should come stock with one of these.
Easy add to my light weight LIV camper. Adds to confidence with a computer monitoring trailer motion. It can react and correct before i detect a problem.

Sounds like piece of mind when on the road, Robert. Where are you headed off to this summer with the camper?

I installed it professionally a year ago, and it is still not working correctly. I'm not sure if it was not wired correctly or what the problem is. When it is on, my electric brakes don't work on the trailer. When it is off, my breaks work fine, but I don't have the sway control. I'm not sure what to do next.

Marvin, in this case I would use page 8 in the manual to make sure that it is wired correctly. Take a look at Figure 1 on page 9 to make sure the wiring on the left side of the trailer is correct. Check that only the PURPLE and WHITE wires are connected to the left side trailer brakes wired in parallel and not in series. It is very important that the trailer brake controller wire from the tow vehicle [blue wire] is ONLY connected to the BLUE wire on the TSC and NOT connected directly to the trailer brakes. I would then take a look at the troubleshoot able on page 10 - match the way the LED is behaving to the chart to see what is going on with it. If this does not work for you please let me know.
Had my dealer install the unit. After some wiring issues on my trailer were sorted out, the Tyson trailer sway control system works great. I can really tell a huge difference on the down hills when my 7,500 pound 34" bumper pull travel trailer really wanted to push me down he hill causing trailer sway. That has been eliminated.
INRECENTLY INSTALLED MY ASSYMETRIC BRAKE CONTROLLER REALLY HAPPY ABOUT THE UNIT,I SENT YOU PHOTO OF THE INSTALLATION.
As a 76 year old woman and single RV-er with a Micro Minnie Winnie this was the best and only option I could find. The traditional sway systems I found were too heavy, complicated for my arthritic hands, and the heavy hitch receiver had to stay on my truck which made my truck too lon for my garage. I paid a local shop recommended by etrailer and was installed for about $300. I love the way the electric system smoothly adjusts any sway over many different driving conditions and wind. I’m very very pleased with this sway control electronic unit for my Winnebago Micro Minnie RV trailer!
Would rate it as excellent but my first one malfunctioned after 5 years. I've just installed my second one. I hope it lasts more than 5 years, but if it doesn't, I will buy a third one. The failure mode was on rough roads, instead of going into standby, it would pulse the brakes hard. Tech support said it was likely due to electronic circuit failure. (2 year warranty).
This sway control unit works very well. We tow our 27' trailer behind our Nissan Titan without a weight distribution hitch and have no sway or control problems. We towed is across Idaho a couple months ago and encountered 20+ mph crosswinds, gusting to 30+ MPH and didn't experience any sway even on a two lane road where 10 wheeler trucks were passing the opposite direction. There was large blast of wind as we passed them going the opposite direction and the trailer would move but immediately return to normal tracking.
The only thing I would improve is the ability to see when the sway control is active. There's no way to see the tiny light flashing multiple times per second when it's way back on the trailer. Having something like 2 lights of different colors would be nice so a different light color could indicate the sway control is actively preventing sway.
No sways since installed but I too scared to go service test it. We had a bad situation happen once, and nothing since the Tucson system has been installed. I love the little green light that tells me the system is good and ready.
Took about 3 hours to install, but was easy. I was looking for peace of mind after a nasty accident caused by trailer sway and the system, especially the LED light that I can see in my rearview tells me when the system is working..so far, so good!
Purchased sway control for my travel trailer that doesn't like to follow the rules much less my truck. It pulls very well now.
I purchased this to use with a 23' Airstream travel trailer that I am towing with a Land Rover Discovery. Land Rover, unfortunately, does not recommend the use of weight distribution hitches on their vehicles so it was necessary to find some other way to control sway. I used this Tuson Sway Control device plus a Curt Friction Sway Control. With this setup we have been able to safely tow our Airstream through difficult conditions such as high winds, rain and mountain passes. In high winds it is noticeable, and extremely impressive, to feel how the Tuson activates the trailer brakes to control sway.
Having said this, I would not recommend towing a trailer of this weight without a weight distribution hitch. We plan to switch our tow vehicle to one that will allow the use of weight distribution (which seems to be any vehicle other than a Land Rover). Even after changing to a setup with a weigh distribution hitch with integrated sway control, I will still be very glad to have the Tuson device installed on the trailer. Were I to purchase another travel trailer I would immediately install another Tuson Sway Control regardless of the tow vehicle and hitch setup. I am actually very surprised that travel trailer manufacturers do not offer this as a pre-installed option on their trailers.
One thing to note for Airstream owners is that Airstream brakes are wired in series which, at least for me, made this not a do-it-yourself installation. My local Airstream dealer charged about $500 for installation which was well worth the price and it works great.
Had this unit installed now for over a year and haven't looked back. Works as advertised, but how would you know when all you need to do is install it, drive it and have no sway control issues with your travel trailer which is exactly what its supposed to do. Little extra thinking and work wiring it up yourself, but the excellent service department provides you with all of the pointers and clarifications that you need to successfully install the unit yourself if you are handy around vehicles and minor automotive wiring. One of the best features for me about this unit is saving on tow vehicle payload weight take ups which seems to be an ever present issue in the RV travel trailer world where the added weight from mechanical RV hitch load levelers and sway control mechanical mechanisms eating up your vehicles payload capacity and also from losing sway control function with mechanical sway control hitches during inclement wet weather.From what I read from fellow RV`rs and their reasons for not choosing this electronic sway controller is seems to be their hesitancy to tackle the minor brake wiring adjustments to your TT`ers brake wiring needed during installation, and they shouldn`t be because its not that difficult. Well worth the money from my perspective!
No sway in 10,000 miles of towing. We are very pleased with the product and highly recommend it.
For the most part it's a waste of money. It's a cool device and when the technology matures it will probably save a lot of bumper pulls. The problem with this product is that the trailer has to have significance way in order for it to work,... and if you are an experienced driver, you've already compensated by the time that happens. It's way is an issue on your trailer then replace the suspension you'll get a much better response

I wanted to reach out to you in regards to your review on the Tuscon braking system. You mentioned that it is taking a lot of sway before the system is working and I wanted to ask a few follow-up questions before I reach out to the manufacturer. Are you using a brake controller as well. If so what brand is it or was it from the factory? Does you GMC have an automatic leveling system? How many brakes do you have on the trailer or how many axles?
Did not work in my case. Have a green status light but sway control never activates. Vendor support is non-existent and their “60-day” return policies only work for “unused and uninstalled” items. If it is defective you are on your own duking it out with the manufacturer.

I reached out to the manufacturer about the experience that you had with the sway controller and it has led me to ask you a few questions. What are the highway or road conditions that you have been pulling your trailer? Tuson advises that the goal of the system is to only apply the brakes when the sway levels approach a medium level at higher speeds and not to activate on the smaller sways or at slower speeds. Are you experiencing sway at lower speeds or in town? Are you also using a sway control weight distribution system or only the Tuson system? You may consider adding on a weight distribution system for in town use. The Tuson system can work in tandem with it for when greater sway conditions apply.
I bought this to tow our Apex Nano (GVWR 6000lb) with our 2013 Land Rover LR4. Land Rover does not recommend a WDH, so we had this installed by our local RV repair shop to help with sway control.
Overall, I'm satisfied with the product. It definitely helps more than the previous sway controller (Hayes) that our dealer had installed when we first purchased our trailer. On a recent 200+ miles trip, we could see (thanks to the LED light) the device activate on several instances to limit sway. It made for a more pleasant trip overall. I haven't towed with strong winds yet, so that will be for another time.
Note that the first 30 minutes or so were rather rough, but things calmed down afterwards. My hypothesis is that this is related with the initial sway control device calibration.
eTrailer was also able to price match a lower price I found elsewhere. Great service!
I got one of these for our Hawk 2-horse bumper-pull trailer about a year ago. In central Illinois we often have 30-50 mph gusty wind, so my wife & I have had several opportunities to put this thing to the test--and it passed with flying colors! On top of it doing a good job controlling sway, it is so convenient to be able to simply hookup and go, and there is no extra equipment to deal with when backing up.
I tow a 23' travel trailer with a Durango. I purchased this to eliminate sway from passing trucks on the highway. I don't think it helps very much for that application since I don't feel much improvement in the sway from those events and I never see the monitoring light indicate it has triggered.
This is a great "peace of mind" product. It works great on my Palomino Puma XLE 25TFC toy hauler. This trailer is 30' long 12' tall and 8' wide. It weighs 6027 lbs empty and it is a terror to pull. This trailer starts swaying with the slightest breeze. I first installed a Husky centerline sway control load distribution hitch and that helped a little bit but after installing the Tuson, sway has litteraly stopped. The installation was pretty involved and you better be comfortable with cutting up your existing break wires. The installation also took me a little over 5 hours but it was well worth it. This kit also comes with an LED control light that mounts on the front of the trailer to let you know when the trailer is experiencing sway. The light will turn red until the sway is corrected. I saw the light turn red several times but by the time the red light comes on the sway is corrected and you never feel it. I highly recommend this product it is worth every penny.
just installed it. next week I'll be giving a 200 mile test drive.pulling a 9000 lbs ,36ft. bumper pull with a F-150. truck has pulled this RV before with some fish tailing even with a propride P3 hitch so I'm hopping the Tuson will take the rest out. let you know.
So far after first trip with this installed it is working seamlessly. If I had not towed this 36ft toyhauler before I would say its not doing anything. Before the trailer would push the truck around with every wind gust or truck passing. With it installed, nothing, no pushing, no steering correction needed, the trailer just follows the truck, even when I am trying to make it sway. Very good product and one that I am suprised is not installed at the factory on bigger trailers.
Do you have a question about this Weight Distribution Hitch?
