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)
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.
