Nobody wants sag between their tow vehicle and trailer while towing. Different options are available to solve this dilemma, including both weight distribution and air bag suspension. Both will raise the back of the tow vehicle, reducing some of the sag caused by the trailer's tongue weight, but we wanted to investigate the difference between the two and discover the secrets behind each one.
Weight distribution hitches are designed to improve the balance of weight between the tow vehicle and the trailer. These systems use a hitch with spring bars that shift weight from the back of the tow vehicle to the front and rear axles of the trailer. By redistributing the weight, the tow vehicle and the trailer essentially become a single unit, instead of two separate ones. This results in better handling, braking, and a more comfortable ride. It also helps to prevent excessive sway and rear-end sag during turns or while braking.
Airbags are another method for leveling loads. Airbags work by providing additional support to the tow vehicle when it is under heavy load. By adding extra air pressure to the bags, the vehicle raises up and levels with the trailer. This helps to prevent rear-end sag and improve handling. Airbags are often used as an alternative to weight distribution systems, as they can provide the support without the need for a separate hitch system.
