The ARB Air Locker(TM), the world's premier traction aid, supports your driving in all road conditions. With the flip of a switch, it provides instant locking, and its ultra-durable design, capable of being engaged at speed, allows you to tackle the harshest terrain. The key to the Air Locker lies in the pneumatically operated locking system within the differential. When engaged, it prevents the internal differential gears from rotating, ensuring the axle shafts do not rotate independently. By locking the ring gear rotation to both wheels, it consistently delivers maximum traction. When unlocked, it operates just like a conventional open differential. Vehicles equipped with an Air Locker can travel at lower speeds with greater safety and control, significantly reducing both vehicle damage and environmental impact.
