Air Lift Company has been developing air spring suspension products for more than 70 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 was proven during the early years of stock car racing. Air Lift products were used by most of the stock car racing teams for twenty years and the sponsored cars were among the toughest competitors on the NASCAR Grand National Circuit. 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 we started using air helper springs on the motorhomes 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 motorhome suspensions. Air Lift has won more SEMA awards for air spring development products than any other company.
