The world's premier traction aid, the ARB Air Locker(TM), keeps you moving in all conditions. With the flip of a switch, you can engage instant locking, and its ultra-rugged design allows for operation at any speed, enabling you to tackle the toughest terrain. The advantage of the Air Locker lies in its pneumatic locking system inside the differential. When engaged, the Air Locker prevents the internal differential gears from rotating, which keeps the axle shafts from turning independently. By locking both wheels directly to the ring gear's rotation, the vehicle maintains the maximum possible traction at all times. When unlocked, it functions just like a conventional open differential. Vehicles equipped with an Air Locker can be driven at lower speeds with greater safety and control, significantly reducing both vehicle damage and environmental impact.
