Differences Between Friction Based Sway Control and Dual Cam System For a Trail-Bay Travel Trailer


I will pickup a trail-bay travel trailer this friday and they are to install a equal-i-zer hitch with 4-point sway control, but I like what I have seen on your dual cam HP. please help me make the best choice, as it is my safety involved here. thanks gb

The biggest difference between an Equal-I-Zer friction style sway control and a system like a Reese Dual Cam High-Performance Sway Control # RP26002 is that the friction style is passive and the dual cam is active.

What is meant by that is that the friction style does not do anything to prevent sway, it only acts minimize it once it has already started, which for some people it will work. However, the dual cam system works to prevent sway before it begins. This system will proactively and aggressively resist the start of sway by forcing the vehicle and trailer to ride in straight line. In tight turns the dual cam lifts the outside spring bar which increases towing performance by leaning the tow vehicle and trailer into the turn.

Also, friction based sway control needs to be removed in inclement weather, which I personally would not want to worry about additional trailer sway in inclement weather. It will also need to be removed when backing up.

With all that being said, what prevents sway the best is properly loading your trailer. You will want the weight of whatever cargo in your trailer as far forward as possible.

Check out the FAQ article I attached on weight distribution systems that has a section on sway control.

I also attached an installation video for the # RP26002 for you to check out.
