Air Locker Quad O-Rings (Pair) - For Newer Style ARB Diff Locks

These quad o-rings are fitted inside your ARB Air Locker, creating the essential seal for the air-actuated engagement mechanism. If you're servicing your diff or have an air leak, these seals are the likely cause. The original o-rings can become hard, brittle or get damaged, causing them to fail. A leaking o-ring prevents your locker from holding air pressure, meaning it won't engage. This leaves you with a standard open differential exactly when you need maximum traction, potentially stopping you dead in your tracks on a challenging obstacle.

(some early 3 piece lockers have a groove machined in the seal carrier and use the larger seal)

Features & Benefits

• Supplied as a pair, providing a complete seal replacement for one ARB Air Locker.
• Made from a quality, oil-resistant material to ensure a long-lasting, reliable air seal inside the differential.
• Direct-fit replacement parts for a straightforward installation when servicing your locker.
• Restores proper air pressure sealing, which ensures your locker engages reliably every time you hit the switch.

Vehicle Fitment

• Suits newer style ARB Air Lockers.

Please note: This part is designed to fit the ARB Air Locker unit, not a specific vehicle model. Please confirm you have a newer style ARB Air Locker before purchase. Contact us with your locker's serial number if you require assistance to confirm fitment.
