The world's premier traction aid, the ARB Air Locker(TM), supports your driving in any situation. With the flip of a switch, the Air Locker engages instantly, and its ultra-rugged design allows for activation at any speed, enabling you to conquer even the toughest terrain. The advantage of the Air Locker lies in its air-operated locking system inside the differential. When engaged, it prevents the internal differential gears from rotating, stopping the axle shafts from spinning independently. Because both wheels are locked directly to the rotation of the ring gear, maximum traction is maintained at all times. When disengaged, it functions just like a conventional open differential. Vehicles equipped with an Air Locker allow for slower, safer, and more controlled driving, significantly reducing vehicle damage and environmental impact.
