The world's premier traction aid, the ARB Air Locker(TM), keeps you moving in any situation. With the flip of a switch, it engages instantly, 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 housed within the differential. When engaged, it prevents the internal differential gears from rotating, which in turn stops the axle shafts from rotating independently of each other. With both wheels directly locked to the rotation of the ring gear, the vehicle maintains maximum traction at all times. When unlocked, it functions as a conventional open differential. Vehicles equipped with an Air Locker can be driven more slowly, safely, and with greater control, significantly reducing both vehicle damage and environmental impact.
