The ARB RD157 can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world’s best traction aid, ARB Air Lockers keep you moving in all conditions.
Air Lockers from ARB are currently available in over 100 configurations to suit a wide range of off-road and 4×4 vehicles from around the world. Because an air locker is only engaged when needed, it can be installed in BOTH the front and rear axles, with separate switches independently controlling the RD157 air locker from within the off-road truck or vehicle.
Installation of the ARB RD157 air locker should be performed by a qualified differential technician, although no special tools or skills are required apart from those necessary for fitting a standard differential. When installed with an ARB air compressor (high output or mini), the ARB locker system is supplied as a complete kit which contains all of the parts necessary for proper installation, including industrial grade control switches, air lines and fittings. ARB offers two compressor models suitable for Air Locker operation (high output air compressor or mini air compressor). A dedicated air activation system is available which is extremely durable and compact. Alternatively a larger compressor can be specified, which is also perfect for inflating tires, air mattresses and a host of other applications where compressed air is required.
The world’s premier traction aid, an ARB Air Locker 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.
