The world's leading traction aid, the ARB Air Locker(TM), supports driving in all road conditions. With the flip of a switch, it allows for instant locking, and its rugged design enables engagement at any speed, allowing you to tackle the most demanding terrain. The advantage of the Air Locker lies in its pneumatically operated locking system located inside the differential. When engaged, it prevents the internal differential gears from rotating, keeping the axle shafts from spinning independently. Because both wheels are directly linked to the rotation of the ring gear, the vehicle always maintains maximum traction. When unlocked, it functions just like a conventional 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.
