At CURT, we understand the importance of ensuring safe and reliable towing experiences. That's why we developed an advanced electronic sway control system that prevents sway during emergency maneuvers, poor road conditions or during heavy winds. Our system is compatible with a range of truck types, making it a reliable solution for all drivers. Our advanced sway control system can bypass the trailer braking controller, acting independently of the driver to limit trailer sway in emergency situations. It is equipped with unique, motion-sensing technology that detects trailer movements not controlled by the weight distribution hitch. Our advanced patent-pending microprocessor technology can quickly and safely apply the trailer brakes to limit sway and ensure a safer towing experience.
