The Husky Center Line torsion weight distribution and sway control system is the industry's first self centering sway control system, to provide you with complete confidence during your towing experience. Compression cylinder action and torsion spring bars work together to distribute weight and oppose trailer sway before it begins, keeping your trailer straight and on-center, giving you increased control.
