Genuine ARB seal housing kit for keeping your Air Locker's air actuator sealed and responsive. The housing feeds compressed air into the locker, and its O-rings are the wear item that slowly leaks with age — this kit renews them so the locker engages the moment you flip the switch.
Fit it during a diff rebuild or when a locker starts to lock slowly. Genuine ARB parts match the original bore and groove dimensions for a lasting, airtight seal.
