The world's premier traction aid, an ARB Air Locker(TM) keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.Vehicle Fitment 2003-2023 Toyota 4Runner 2007-2014 Toyota FJ Cruiser 2003-2008 Toyota Land Cruiser 2004-2023 Toyota Tacoma 2007 Toyota Tundra Please verify exact fitment for your specific vehicle configuration before purchase.Manufacturer Part Number: RD121Image is for reference only; actual product may vary by application.
