The TrackPro is a revolutionary hitch that not only handles weight distribution but sway prevention as well by using the combination of loaded spring bars, friction L brackets and an integrated hitch head. As the trailer tries to sway it puts a heavier load on one side of the bars, as this happens the spring bars will pivot on the hitch head and balance load working with the friction L brackets to prevent and control trailer sway. The TrackPro will also conquer weight distribution at the same time, putting more weight on the towing vehicles front tires which increases steering control and braking giving you a safer and easier driving experience.
