ARB Seal Housing Assembly for Air Locker Differential

The ARB Seal Housing Assembly is a genuine replacement service part for the ARB Air Locker air-operated locking differential. It is also called the Air Locker seal housing or air seal housing. The housing channels compressed air into the locker so it can engage on demand. A worn or damaged seal housing can cause air leaks and stop the locker from engaging reliably.

Key Features:

• Official ARB service part made for Air Locker differentials
• Seal housing with an air feed tube that delivers air to the locker
• Sealing O-rings designed to hold air pressure inside the locker
• Replaces a worn or leaking seal housing when you service or rebuild an Air Locker
• Designed for use with ARB Air Locker front and rear differentials

During installation, the O-rings should be lubricated and the housing slid gently onto the carrier bearing journal. This helps the O-rings seat without twisting. Follow the ARB installation guide for your Air Locker model.

Restoring the seal helps your Air Locker keep working reliably on the trail, whether you use it for off-roading, recovery or heavy-duty work.
