ABOUT THIS PRODUCT

Created to provide 100% traction on demand, without sacrificing any of your vehicle's highway driving performance, ARB Air Lockers employ a 12 volt ARB Air Compressor (sold separately) designed to activate and deactivate a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flip of a switch and all within the comfort of the driver's seat.

The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional 'open' differential.
