The world's premier traction aid, the ARB Air Locker(TM), supports your driving in all conditions. It locks instantly with the flip of a switch, and its ultra-durable design allows for operation at any speed, enabling you to tackle even the most extreme terrain. The advantage of the Air Locker lies in its pneumatically operated locking system inside the differential. Once engaged, the internal differential gears are prevented from rotating, which in turn stops the axle shafts from rotating independently. Because both wheels are tied directly to the rotation of the ring gear, maximum traction is maintained at all times. When unlocked, it functions just like a conventional open differential. Vehicles equipped with an Air Locker can drive at lower speeds with greater safety and control, significantly reducing the risk of vehicle damage and environmental impact.
