SwayPro® Weight Distributing Hitch

Imagine this: you and your family have loaded your travel trailer and are heading to your vacation destination. On the road, you are about to pass an 18-wheeler. As the truck passes, your trailer begins to sway back and forth or fishtail. If you have ever experienced this, you know how scary it can be and that maintaining control can be quite difficult. Trailer sway is one of the main causes for accidents involving trailers and, for many people, it is the reason they put their trailer away for good after only a few trips. The good news is that, with the use of our hitch, the SwayPro, you can prevent sway in any type of weather.


“I just had a Blue Ox SwayPro Hitch put on my snowmobile trailer and Chevy Silverado 1500. The trailer had quite a bit of side to side sway with cross winds and passing semis. After installing a SwayPro, the sway is gone. I feel so much more comfortable towing with this system in place. Great Product! Thank You!

What Causes Trailer Sway?

Trailer sway occurs when a force from the side of the trailer, such as wind, causes the trailer to sway side to side. Once a trailer begins moving in this back and forth motion, it can quickly get out of control. Trailer sway can also occur as a result of what is referred to as “bow wind” from a semi-truck as it passes, creating an intense and sudden gust of wind. Uneven road conditions in rural areas or construction zones are also a common cause of trailer sway. While drivers may be able to avoid these bumpy areas of road, wind is not a factor that can be changed. Whether we like it or not, sway happens.

Stop Trailer Sway Before it Starts

SwayPro by Blue Ox is a weight distributing hitch that prevents trailer sway. SwayPro relies on tension to keep its spring bars taut and the brackets ensure that pressure from the spring bars will keep the trailer in line with your towing vehicle. SwayPro uses weight distribution technology with built-in trailer sway prevention. It is computer designed and geometrically optimized to ensure the highest quality trailer sway prevention and weight distribution without extra adjustments. Sway prevention is built into the hitch head, which has an open design, allowing for easy access to tighten the hitch ball. With this built-in sway prevention, in the event that your trailer would sway, one of the sway bars becomes more loaded than the other, keeping the trailer centered and in line with the towing vehicle. This built-in sway prevention is safer than traditional friction sway controls that are designed to slow down the trailer sway, but does not bring the trailer back in alignment with the towing vehicle.

Easy to Use Design

SwayPro is designed with the user in mind, making it the most user-friendly trailer sway prevention system on the market today. Enjoy the ease of quickly hooking up and disconnecting the trailer. There is no need to disconnect prior to backing up. There is no need for friction pads, resulting in a smooth and quiet ride. There are no additional clips or pins thanks to the self-locking spring bars that automatically lock into place by simply rotating the bar 90 degrees. The spring steel bars are able to flex for optimal sway prevention and weight distribution. SwayPro has a limited lifetime warranty.

The SwayPro hitch is compatible with a variety of towing vehicles from minivans to large ¾ ton pickups. Simply determine what type of vehicle and hitch head you will be using, the type of trailer coupler your travel trailer is equipped with, and select the appropriate tongue weight.

Stop Sway Before It Starts

Trunnions on each side of the Swaypro™ hitch head employ a caster effect, working with spring bars, to constantly push inward, keeping the trailer in line.
