BMpro® Sway control is popular for use on Jayco, Alko and Dexter electric braking systems. (Note: Wholesale prices available to trailer builders or repairers. If you are interested in installing this sway control, we invite you to contact Couplemate.)

The patented controller asymmetrically engages electric brakes on the left or right-hand side, depending upon the dynamics of the sway event.

  • Mount the SwayControl box on the underside of the caravan chassis.
  • It is wired directly to the caravan braking system and continuously monitors yaw to detect sway.
  • If sway is detected the SwayControl automatically activates the caravan brakes, creating resistance to bring caravan and vehicle under control.

The subject of towing safety is on everybody’s lips with the most recent incident of a caravan rollover in North Queensland and with Caravan Industry Association of Australia launching the towing guide earlier this year.

Caravan Sway Control Works

Sway Control distinguishes between safe maneuvering and dangerous caravan sway that does not require driver intervention.

With independent control of left and right-hand side caravan braking systems and continual closed-loop feedback, the SwayControl quickly and effectively applies the necessary braking force needed to correct caravan sway.

Use in conjunction with your favourite tow hitch. Friction sway control hitches and specialised tow balls are required on mechanical braking to reduce trailer sway.

Further, BMPRO® sway control systems reduce sway from low tyre pressures on vehicle and trailer and provide more stability to the tow vehicle for highway road conditions.

Note: SwayControl automatically disengages when used in offroad conditions.
