As one of the world's leading traction support devices, the ARB Air Locker supports your driving in any situation. It can be locked instantly with the flip of a switch, and its ultra-durable design allows for operation at any speed, enabling you to tackle the most demanding terrain. The defining feature of the Air Locker is its air-operated locking system inside the differential. When engaged, it prevents the internal differential gears from rotating, thereby stopping the axle shafts from spinning independently of each other. With both wheels directly coupled to the rotation of the ring gear, the vehicle maintains maximum traction at all times. When disengaged, it functions just like a conventional open differential. Vehicles equipped with an Air Locker can be driven more safely and with greater control at lower speeds, significantly reducing both damage to the vehicle and impact on the environment.
