Tough molded polyurethane construction and easy installation gives your RAM the boost you need to handle those heavy loads. The kit includes 2 air springs, hardware and instructions and no drilling is required.

Engineered as an add-on helper spring for coil spring suspensions, AirLift 1000 features an easy do-it-yourself installation with simple hand tools. Most kits can be installed in about an hour, with no drilling required!

Air Lift 1000 is made from a very durable polyurethane material and is inserted into the vehicle's stock coil springs. When filled with air, it increases the spring rate, or ability to support a load. Because of its design, Air Lift 1000 products are best stated as load support products, rather than lifting products.

When charged with air the bag will grow in all directions much like blowing up a balloon. Controlling the growth requires a coil spring to hold it into shape and funnel its spring energy into its length. The bag's spring rate comes from compressing its length and also from the bag being wedged in between the coils of the spring. Over inflating the bag can cause the wedging to become too severe and therefore causing the material to thin, which in turn, causes a decrease in spring rate and a premature failure.
