Why Air Suspension?

There are several load-assisting products available on the market today. While most options effectively address squat for a loaded vehicle, they present the same core challenge as the factory suspension. They are static solutions that leave your vehicle’s suspension tuned for a single driving state: loaded. This results in a whole new set of complications, namely an uncomfortable ride whenever the vehicle is not carrying a heavy load.

Air springs (also called air bags) are the only load support products that offer adjustability. Adjustable air spring kits work with your existing suspension to level your vehicle to normal ride height, thus eliminating the hazards of squat and the inconvenience of a static suspension. Adjustable air suspension enables you to change the spring rate of your vehicle on-the-fly by simply inflating the air springs when towing or hauling and deflating when riding empty.

Air springs can be adjusted using an on-board air compressor system or by using the included Schrader valve (the same valve used for filling most tires).

CALIFORNIA WARNING: Cancer and Reproductive Harm -
