The world's premier traction aid, the ARB Air Locker(TM), supports driving in all road conditions. With the flip of a switch, you can lock the differential instantly, and its ultra-rugged design allows for operation at any speed. This enables you to conquer even the most extreme terrain. The advantage of the Air Locker lies in its pneumatically operated locking system inside the differential. When activated, it prevents the internal gears from rotating, keeping the axle shafts from spinning independently. By directly coupling both wheels to the rotation of the ring gear, maximum traction is maintained at all times. When unlocked, it functions 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.
