The world's premier traction aid, the ARB Air Locker(TM), supports your driving in every situation. With the flip of a switch, you can achieve instant locking, and its extremely robust design allows for engagement at any speed, enabling you to tackle the most demanding terrain. The strength of the Air Locker lies in its pneumatic locking system inside the differential. When activated, it prevents the internal differential gears from rotating, stopping the axle shafts from spinning independently of each other. Since both wheels are directly connected to the rotation of the ring gear, maximum traction is maintained at all times. When unlocked, it functions just like a conventional open differential. Vehicles equipped with an Air Locker can drive more slowly, safely, and with greater control, significantly reducing both vehicle damage and environmental impact.
