The world's premier traction aid, the ARB Air Locker(TM), supports your driving in any situation. With the flip of a single switch, the Air Locker engages instantly, and its ultra-rugged design allows for activation at any speed, enabling you to traverse the most demanding terrain. The advantage of the Air Locker lies in its pneumatically 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 one another. Because both wheels are locked directly to the rotation of the ring gear, the vehicle maintains maximum traction at all times. When disengaged, it functions just like a standard open differential. A vehicle equipped with an Air Locker can be driven more slowly, safely, and with greater control, significantly reducing both vehicle damage and environmental impact.
