Weight Distribution Hitches or Sway Control Hitches – Which is best?

Weight distribution hitches are a popular topic among the travel trailer community. But there's a bit of confusion out there about the difference between weight distribution and sway control.

What is a weight distribution hitch?

Weight distribution hitches only transfer the tongue weight of the trailer from the rear of the tow vehicle to the front. By doing so, weight distribution hitches enhance stability and control, but they do not control trailer sway.

What is a sway control hitch?

Sway control hitches are designed to control the side-to-side movement in the trailer. A sway control hitch will incorporate some sort of friction adjustment at the hitch head or along the trailer frame, usually using two friction plates. Trailer sway is commonly caused by factors such as wind gusts, passing vehicles, or uneven road surfaces.

While some weight distribution hitches have built-in sway control mechanisms, it's important to note that not all weight distribution hitches include sway control features. Please note that the specific features and capabilities of weight distribution hitches and sway control hitches can vary between different brands and models. Many rely on the weight distribution aspect of the hitch to aid in controlling sway.

Do I need a trailer sway hitch or weight distribution hitch?

The Hensley Arrow goes one step further by including weight distribution AND eliminating sway. By using a unique linkage system that effectively moves the pivot point to the rear axle of the vehicle. The Arrow allows movement on the ball in every direction except side-to-side. Side-to-side movement is forced to go through the linkage system which is one directional. From the trailer side, the linkage is solid. Pivoting by the linkage must be initiated through the tow vehicle. The system’s design is inherently stable. Best of all, it functions mechanically, without the use of friction so it exhibits consistent and predictable behavior regardless of changes in weather or road conditions.

In summary, the main difference between a weight distribution hitch and a sway control hitch lies in their primary functions. A weight distribution hitch evenly distributes the trailer's weight across all axles, while a sway control hitch specifically addresses and minimizes trailer sway. Don’t settle for one or the other, get both with a Hensley Arrow® and say goodbye to trailer sway for good.
