Genuine ARB spare, matched to a specific Air Locker application. This is the genuine ARB Air Locker seal housing kit (part number 081815SP), an internal service part for ARB's air-operated differential lockers.
The seal housing carries the O-rings that seal compressed air as it passes into the Air Locker, allowing the locker to engage and release on demand. Over time these seals wear and the locker can lose air or engage slowly — this kit restores that sealing surface with the correct ARB components.
- Genuine ARB Air Locker service part — part number 081815SP
- O-rings included for a complete reseal
- Designed for a specific Air Locker / differential application
Fitment: ARB Air Locker spares are matched to the differential, not the vehicle. Confirm part number 081815SP against your Air Locker before ordering.
Honest note: this is a spare part, not a complete Air Locker. If your locker has deeper wear (spline, seal ring, or bearing damage) you may need additional components to finish the rebuild.
