This patented product is Reese Products main technique for controlling trailer sway. Unlike the friction sway control, this approach works to control sway from the start rather than just resisting sway once it's begun. And it works only when needed. The advantage of the dual cam system is its ability to forestall sway in addition to sway resistance. It works to hold down the start of swaying activity while at the same time allowing free and easy vehicle and trailer interaction. Another advantage of the dual cam system is that it's installed on the trailer and therefore doesn't require adjustment every time the towing vehicle and trailer are hooked up, unless hitch weight or tow vehicle loading are changed.
