Trailer sway can be caused by crosswinds, poor trailer loading (load being too far back), or inadequate spring bar tension in the weight distribution system. The use of a weight-distributing hitch by itself may help limit trailer sway by evenly distributing the weight of the load, but it will do little to improve sway caused by crosswinds. To help control sway, a sway-control device is recommended for most standard weight distribution systems. Because sway control is so important, it is built into many systems. If you want to wait to add on a sway control device, you will likely be limited to a bar-style friction sway control. Trailer sway devices come in 2 basic types - those that reduce sway once it has begun and those that work to prevent sway altogether. Reduce Sway Sway control systems that reduce sway typically rely on friction to keep your trailer from shifting, preventing sway from increasing
