A weight distribution hitch is a device that is used to distribute the weight of a trailer more evenly between the trailer and the towing vehicle. This can help to improve the stability of the towing vehicle and trailer, and can also reduce the amount of sway that the trailer experiences. Weight distribution hitches are typically used with trailers that are over a certain weight, or that are particularly prone to swaying.
There are many different types of weight distribution hitches available, and the best type for a particular application will depend on the weight of the trailer, the type of towing vehicle, and the driving conditions. It is important to choose a weight distribution hitch that is properly rated for the weight of the trailer, and to install it correctly. Improperly installed weight distribution hitches can actually make the towing vehicle and trailer less stable.
