The King air shocks have been around for a long time. The quality of materials, unique design features and precise tolerances are what set these air shocks apart from the competition. King air shocks offer infinite height and pressure settings in addition to easily adjustable velocity sensitive internal valving. Tubular, hard chromed shafts further reduce the weight and urethane seals insure proper sealing and long life. The quality of the internal sealing allows you to set-up your air shock to also function as a bumpstop if needed. Critical importance is placed on the Schrader valve of an air shock so King developed a unique Schrader cover that mounts to the body of the shock instead of the valve itself to protect the valve and act as a double seal giving you gas it and forget it peace of mind.
