What devices are used to control sway on loaded trailers?

Sway control hitches or stabilizers are specifically designed to minimize the lateral movement of trailers when they are loaded. This lateral movement, or sway, can be dangerous, especially at high speeds or in windy conditions. The sway control mechanisms work by distributing weight evenly across the trailer and connecting it securely to the towing vehicle, which helps maintain stability. These devices can include mechanical systems that apply friction or limit the pivot point of the trailer, keeping it aligned with the tow vehicle and reducing the risk of swaying.

Other devices listed may contribute to overall towing safety, but they do not directly control sway. Wind deflectors improve aerodynamics and reduce drag, while anti-lock brake systems enhance braking performance but are not designed to manage lateral movement. High-performance tires can provide better traction and stability under certain conditions; however, they do not actively control the sway of a loaded trailer. Thus, sway control hitches or stabilizers are the dedicated solutions for managing this specific issue.
