Friction sway control systems are devices designed to reduce the swaying motion of vehicles, especially trailers, during travel. They work by using friction to create resistance against the lateral movement caused by wind or uneven road surfaces. This helps maintain stability and improves safety while driving. These systems typically consist of friction pads or materials that are applied between the trailer and the towing vehicle. When the trailer begins to sway, the friction generated helps to counteract the motion, allowing for smoother handling. This technology is particularly beneficial for those towing heavy loads or navigating challenging driving conditions.
