Air Lift

The Air Lift Company has been developing air spring suspension products for over 50 years. The original product, a rubber air spring inserted into a car's factory coil spring, was developed and patented in 1950.

The versatility of Air Lift air springs were proven during the early years of stock car racing. Air Lifts were used by most of the stock car racing teams for twenty years or so until the racing suspensions evolved to more sophisticated systems. The Air Lift Company sponsored cars were tough competitors on the NASCAR Grand National Circuit. The Air Lift Company has the longest history of product development dedicated solely to the development of light vehicle air suspension products.

First, in the 1950s, Air Lift pioneered the use of air spring inserts in coil spring suspensions. Then, in the 1960s, Air Lift introduced the use of sleeve-type air springs on pickup truck suspensions. During the 1980s Air Lift started using air helper springs on motor homes and ambulances. Street rods and lowered vehicles were the target in the 1990s. Today's products are an evolution of Air Lift's breakthrough development programs applying the use of air springs in light truck and motor home suspensions. Air Lift has won more SEMA awards for air spring development products than any other company.
