The ARB Air Locker(TM), the world's premier traction aid, supports your driving in any conditions. With the push of a button, it locks instantly, and its ultra-robust design allows it to be engaged at any speed, enabling you to tackle the most demanding terrain. The advantage of the Air Locker lies in its pneumatically operated locking mechanism inside the differential. When engaged, it prevents the internal differential gears from rotating, which in turn stops the axle shafts from spinning independently. Since both wheels are locked directly to the rotation of the ring gear, maximum traction is maintained at all times. When disengaged, it operates like a standard open differential. Vehicles equipped with an Air Locker can travel more slowly, safely, and with greater control, significantly reducing both vehicle damage and environmental impact.
