A weight distribution hitch (WDH) system transfers tongue weight from the tow vehicle’s rear axle to the front axle and the trailer’s axles. This redistribution improves steering control, braking performance, and overall vehicle stability by leveling the tow vehicle and trailer, reducing sway and porpoising. For example, without a WDH, a heavily loaded trailer can cause the rear of the tow vehicle to sag significantly, diminishing headlight effectiveness and increasing the risk of trailer separation.
The enhanced stability offered by a WDH is crucial for safe towing, especially with larger trailers or at higher speeds. By more evenly distributing weight, it minimizes the strain on the tow vehicle’s suspension and reduces tire wear. Historically, trailers were smaller and lighter, making specialized hitches less critical. As trailers grew in size and weight, the need for a system to manage the increased load became apparent, leading to the development and widespread adoption of weight distribution hitches.
