The world's premier traction aid, the ARB Air Locker(TM), supports your driving in all road conditions. With the flip of a switch, you can engage the lock instantly, and its ultra-rugged design allows for operation at any speed, letting you tackle 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 differential gears from rotating, stopping the axle shafts from turning independently. Because both wheels are locked directly to the ring gear's rotation, maximum traction is maintained at all times. When disengaged, it functions as a standard 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.
