Tuson RV Brakes Weight Distribution Hitch - 335TSC-1000

  • Sway Control Only
  • Tuson RV Brakes
  • Prevents Sway

Electronic sway control system helps control and reduces sway in trailers with or without weight distribution. Monitors trailer lateral movement and independently applies the left and right trailer brakes to correct the sway.


Features:

  • Electronic sway control system limits side-to-side movement of trailer during towing
    • Unit corrects sway by independently activating your trailer's left and right brakes
    • More effective than friction sway control systems due to having more force to counteract sway
  • Continuously monitors trailer angle, movement, speed, and other parameters for real-time braking calculations
  • Proprietary algorithm calculates and applies the most effective braking response within milliseconds of detecting trailer sway
  • Independently applies left or right trailer brakes (asymmetric braking) to counteract lateral movement and quickly correct trailer sway
  • Sway control braking is applied for 3/4 of a second to prevent tire flat-spotting and still create enough opposing torgue to correct sway
  • Two modes of brake activation - gust-of-wind activation and building sway activation - to correct trailer sway
  • Automatically disables gust-of-wind activation mode when on rough terrain to prevent unwanted braking
    • Gust-of-wind activation mode remains disabled until rig is back on smooth ground
    • Building sway activation remains active at all times
  • System enters sleep mode after 30 minutes of inactivity to conserve trailer battery
    • System powers on when a brake signal is detected from the brake controller
  • LED light provides system status for easy troubleshooting
    • Indicates normal operation, rough terrain or sleep mode, system power issues and more
    • 10' Cord included for mounting light in easy-to-see location on front of trailer
  • Won't interfere with your brake controller, weight distribution system, or mechanical sway control
  • Compatible with all truck OEM trailer sway control systems and integrated brake controllers
  • Fully sealed, water-resistant construction protects against road spray
  • One-time, maintenance-free installation
    • Module mounts 1' to 10' behind hitch ball, on the trailer centerline
    • Splitting electric trailer brake circuit into 2 separate circuits is required for independent left and right side braking
    • 14-Gauge wiring (sold separately) splices into trailer's brakes and connects to trailer's 12-volt battery, breakaway switch, and trailer plug


Specs:

  • Application: trailers with 1 to 4 axles (2 to 8 brake assemblies)
    • Compatible with electric trailer brakes only
  • Dimensions: 5-3/4" long x 3-1/2" wide x 2-1/4" tall
  • 2-Year warranty

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.

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.

So far, so good. No real swaying... minor swaying in heavy side-winds. Easy installation for a DIY person.

Ask the Experts about this Tuson RV Brakes Weight Distribution Hitch

  • Sway Control and Brake Controller for 2016 Volkswagen Touareg TDI
    I recommend the Lippert Sway Command # LC380605 over the Tuson # 335TSC-1000. The Lippert requires less wiring for a simpler installation. You would never be towing more than 2 axles with your 2016 Volkswagen Toureg TDI so the Tuson system would be overkill for you. For the brake controller the wiring is not as complicated as many believe. We have a article (linked below) that will walk you through all the steps and extra parts necessary to install a hard wired brake controller. I recommend...

  • Great Trailer Sway Control with the Tuson Electronic Sway Control and the Chevrolet Silverado 1500
    The Tuson Electronic Sway Control, part # 335TSC-1000, is a great addition to your trailer with electric brakes. It works in the same way the Stabilitrak system of your 2020 Chevrolet Silverado 1500 does. The Stabilitrak senses sway in your Silverado and intuitively applies brakes to correct the sway. When hauling a trailer, your Stabilitrak system has the ability to apply the trailer brakes to correct sway once it has begun affecting your vehicle. Therein lies the key difference...

  • Mounting Orientation of Tuson Electronic Sway Control System
    The label side of the Tuson Electronic Sway Control System for Electric Trailer Brakes # 335TSC-1000 needs to face forward and be in a vertical orientation perfectly centered on the trailer 5-10 feet back from the center of the king pin like what you see in the picture I attached. That said, for the type of sway you are experiencing your best solution it so move your axles further back on your trailer.

The red dot on the label has to be at the trailer's center line and the arrows on the label that say "Mount with this side UP" has to be followed as well. You need to have the module mounted between 5 and 10 feet behind the coupler as well. It looks like your trailer will be a bit of challenge to pull all of this off but your worst case scenario would require you to fabricate...

    The Tuson Electronic Sway Control System for Electric Trailer Brakes # 335TSC-1000 has installation instructions that give a placement location on the center of your trailer and 5-10 feet behind the hitch ball. The unit comes with a wiring harness so you can customize the fit within the parameters given. The placement you show in the photo will not work as it uses a sensor to monitor trailer movement and an algorithm based on that specified mounting location.

  • Can Curt Echo Brake Controller be Used with Tuson Electric Brake Sway Control System
    You can use the Curt Echo # C51180 with the Tuson Electronic Sway Control System for Electric Trailer Brakes # 335TSC-1000 that you also referenced. Essentially the Tuson Control system detects trailer sway and then applies the trailer brakes in a way that is known to reduce the sway. If the # C51180 is also applying the brakes the Tuson would override the brakes and apply them harder if needed to stop the sway. With trailer sway if you apply just the trailer brakes while towing and...

  • Trailer Still Sways with Equal-i-zer Weight Distribution System on a 2018 Ford F-150
    Installing an anti-sway bar on your 2018 Ford F-150 is not going to do much of anything for trailer sway as trailer sway starts on the trailer, not the truck. In order to hammer down what is causing the trailer to sway I first need to know which Equal-i-zer Weight Distribution System you have. You should be using part # EQ37100ET which is rated for 600 lbs - 1,000 lbs. If you are not then that could very well be part of the problem as there won't be enough tension on the spring bars to...

    The electric sway control of your 2019 Ford Ranger is pretty similar to the Tuson Sway Control Unit part # 335TSC-1000 so I would not recommend this system for your truck as it would be a bit redundant. What you have now senses sway and applies the trailer brakes to pull the trailer back basically and stop the sway. The Tuson is a little more advanced as it will apply either side of the trailer's brakes but it's similar enough to what you have that I wouldn't recommend it. Also in general...

  • Should Weight Distribution be Used for Towing a 10K Trailer with a Class A Motorhome
    Weight distribution (WD) systems are really only needed when the weight of the trailer is at least half of the weight of the vehicle towing it. Since this isn't the case with your Class A motorhome pulling your 10K trailer I doubt you really need a WD system but you could benefit from adding some sway control. Typically we recommend using a WD system with integrated sway control but since the WD isn't needed you can just use one of our standalone sway control units. Another thing to note...

    This actually happens with vehicles that use an auto-leveling system pretty often.

This should get the system to compensate for everything. With all that being...
