ARB Air Locker Seal Housing Kit with O-Rings (081802SP) Portable Air Tank it uses an anodized stepWhen an ARB Air Locker gets lazy about engaging, a fresh seal housing kit is usually the cure. The housing feeds compressed air into the locker's actuator, and its O rings are the wear point that eventually leaks this genuine kit reseals that path so the locker snaps in on demand.
