The suspension of any pickup, van, or mobile home that?s weighed down by heavy cargo, permanently affixed equipment, or a trailer is compromised because the rear springs are crushed down to a height they cannot recover from. Ride quality is reduced, and the front of your vehicle points upward. A rear end that is weighed down literally lifts weight off your front wheels, reducing the amount of traction you have for steering and reducing grip the tires have on the road when you need it in fast braking. After enough time, weighed-down springs sag permanently and the effect becomes even worse.

Whether you?ve got a compact pickup truck or large mobile home, Air Lift offers Air Spring support kits that are tailored to your individual needs. For smaller vehicles with coil springs, the Air Lift? LoadLifter 7500XL air springs mount inside the center of your vehicle?s original springs to raise 1,000 pounds to proper ride height. For larger pickups and vans with leaf springs, Air Lift?s RideCONTROLL kit mounts a set of air springs between leaf spring and vehicle frame on each side, adding 2,000 pounds of load leveling capacity. And for commercial vehicles based on light truck or van platforms with heavy hauling needs, the LoadLifter5000 Air Springs supports a maximum of 5,000 pounds per axle. Kits come with necessary brackets and hardware for easy mounting along with easy-connect air lines for manual inflation. While air compressors are not included in these kits, Air Lift also has a selection of pumps that allow power adjustment of your springs automatically, or with the touch of a button.
