Tuson Sway Control (TSC) is the most intelligent electronic sway control system available.
Automatic sway control continuously monitors trailer yaw, rapidly identifies and electrically corrects a trailer sway condition.
Unexpected sway during normal driving conditions activates electronic sway control.
Caution: We recommend sway control be installed by an Auto electrician.
What happens with no sway control?

What is the difference between Tuson and other sway controllers?
Tuson Sway controllers brake on the left or right side of the caravan, independently. Other controllers brake BOTH left and right-hand side simultaneously.
Sway control auto-calculates travel distance and speed, then regulates sway by applying a proper braking level where necessary.
In other words, sway control provides braking to independently increase or decrease voltages to either side of the caravan braking system.
Other brands brake simultaneously on both sides of the caravan.
Why do caravans need sway control?
Variations in driving conditions fall into preventable and unpreventable driving conditions occurring. Examples are:
- Side winds
- Passing Semi-Trailers and Buses
- Windy valleys and terrains
- Incorrect weight distribution
- Uneven tyre pressure
- Suspension installed too far forward of centre
Expect the unexpected when driving on the highway, especially the interstate highways. Tucson sway control continuously monitors your trailer or caravan, adjusting sway when necessary.
A patented asymmetric system (independent left and right side braking) continuously monitors trailer yaw.
A trailer sway condition rapidly identifies sway and as a result, applies braking force on one side of the trailer.
This action directly counteracts trailer sway with minimal speed loss and greater stability control.
How does sway control work?
Each TSC comes with a wired red/green LED light to show the functional status of the unit. Different flashing modes identify diagnostic troubleshooting and is designed to be mounted on the trailer in an easy to see the location from your tow vehicle mirrors.
The TSC is wired directly into the trailer braking system and automatically adjusts to improve braking effectiveness, and even detect off-road towing conditions. Importantly, the wiring diagram is easy to follow and included with your purchase.
Sway Bars and Friction Control
Friction control couplings and automatic sway bars become a secondary tool for anti-sway, but are they needed at all?
Friction control is an older technology used to control caravan sway effectively.
The latest electronic sway control is considered more effective than mechanical sway control. So popular in fact that most caravan manufacturers are now installing this form of sway correction.
Tow Ball or Coupling Weight
Coupling head weight is the first step in sway control. Head weights for tandem trailers under 5% – 7% for caravans will cause sway problem. Weight over 7% add to your car suspension and may lift your headlights.
Coupler head weight between 7% and 10% are suitable for single axle trailers.
Do tandem axles naturally sway less than single axles?
Yes, as a result of the higher amount of road friction applied by tandem axle groups, the amount of sway is reduced.
However, a low coupling head will increase sway even for tandem axle kits.
Therefore, coupling head weight is critical to measure when towing a caravan.
What are the compatible aftermarket brake controllers?
This list is not exhaustive, and if your brake controller is not listed, call us.
Fastest Activation and Reaction Time
The Tuson Sway Controller measures the angle, travel distance, proper braking pressure and speed of the lateral motion of the trailer.
As a result, the controller quickly gets ahead of sway events and applies the brakes on the right or left side of the trailer, where necessary.
Fully Sealed Water Proof
The Tuson Sway controller is sealed and waterproof.
LED Status Light
The RED / GREEN LED is attached to a 3-meter cable and connected to the control box. The flashing LED provides various modes for diagnostic troubleshooting.
Finally, mount the LED in a location that is seen by the driver from his normal seating position. Alternatively, wire the LED to the cabin of the vehicle via a 12 pin plug and socket.
