The world's premier traction aid, the ARB Air Locker(TM), supports your driving in every situation. With the flip of a switch, the locker engages instantly, and its ultra-durable design allows for activation at any speed, enabling you to conquer even the most rugged terrain. The advantage of the Air Locker lies in its pneumatically operated locking mechanism inside the differential. When engaged, it stops the internal spider gears from rotating, which prevents the axle shafts from rotating independently of each other. Because both wheels are locked directly to the ring gear's rotation, you can maintain maximum traction at all times. When disengaged, it functions just like a standard 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.
