The world's premier traction aid, the ARB Air Locker(TM), supports your driving in any conditions. With the flip of a switch, it engages instantly, and its rugged design allows for operation at any speed, enabling you to tackle the most punishing terrain. The advantage of the Air Locker lies in its pneumatically operated locking system within the differential. When activated, it prevents the internal differential gears from rotating, which in turn stops the axle shafts from rotating independently. By directly linking both wheels to the rotation of the ring gear, the vehicle maintains maximum traction at all times. When unlocked, it functions like a conventional open differential. Vehicles equipped with Air Lockers can travel more slowly, safely, and steadily, significantly reducing vehicle damage and environmental impact.
