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

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!

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


Comments
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?

etrailer, thus far, has been nothing but terrific. Fast shipping and what appears to be knowledgeable staff. What more can you ask for? One thing. If you are showing products based on the shopper's tow vehicle be more explicit about additional product/installation requirements/recommendations. Assume that some of the shoppers are new RV'ers. This Tuson Asymetiric Sway Control unit requires the short and inexpensive plug and play wiring connecter thingy for a Subaru Ascent, unless an owner wants to cut into their car's wiring and splice. I doubt that most would prefer to do that. The product was shown based on the owner's car. Show us the whole picture clearly and explicitly. The link in the second paragraph is insufficient. The thingy is inexpensive, but the time wasted is not. Thanks.

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 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.

  • Is Tuson Electronic Sway Control Compatible with 2018 Ram 2500 OEM Controller and 30' Travel Trailer
    The Tuson Electronic Sway Control System # 335TSC-1000 has been confirmed to work with Dodge OEM brake controllers (verified by Tuson) and is compatible with 1 - 4 axles. Since you have an OEM controller on your 2018 Ram 2500 and your 30' travel trailer only has 2 axles this sway control system will work great for you!

  • 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 instructions for the orientation of the Tuson Sway Control part # 335TSC-1000 when installed are very specific. 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...

  • How to Reduce Sway on a 2015 Suburban LTZ with an Auto-Levelling System?
    This actually happens with vehicles that use an auto-leveling system pretty often. Disengaging this system while towing will definitely help as it will allow your weight distribution system to have more tension on the bars, which will help with sway. However, if you are unable to turn off the auto-leveling, then you will need to let the vehicle auto-level and then add more spring bar tension to your system. This should get the system to compensate for everything. With all that being said,...
