The world's premier traction aid, the ARB Air Locker™, supports your driving in any conditions. With the flip of a switch, the locking mechanism engages instantly, and its exceptionally rugged design allows for operation at any speed, enabling you to tackle the most challenging terrain. The advantage of the Air Locker is its pneumatically operated locking system inside the differential. When engaged, the internal differential gears are prevented from rotating, which keeps the axle shafts from spinning independently of each other. By locking both wheels directly to the rotation of the ring gear, maximum traction is maintained at all times. When unlocked, it functions as a conventional open differential. Vehicles equipped with an Air Locker can travel more slowly, safely, and with greater control, significantly reducing vehicle damage and environmental impact.
