With over 200,000 units in use throughout the world, ARB Air Lockers are the choice replacement differential for 4WDers, off-road competitors and commercial users requiring ultra-tough and dependable traction on demand.

The award-winning range continues to expand with the introduction of a number of new models for selected vehicles. Engineered and built in Australia, rear Air Lockers are now available for Hyundai Terracan, Mitsubishi Triton and Pajero models (including live axle and independent rear suspension variants), while front Air Lockers have also been introduced for the Hummer H3. These new additions give owners of most model variants the benefit of selecting both front and rear Air Lockers.

The ARB Air Locker is a replacement differential that gives the best of both worlds — a normal open differential for on-road use, and a positively-locked differential for challenging off-road situations. ARB Air Lockers utilise a 12-volt compressor that delivers high-pressure air to the differential centre, thereby engaging the locking mechanism and preventing the wheels from turning independently. With both wheels tied directly to the rotation of the crown wheel, the vehicle maintains maximum traction when the Air Locker is activated. Whilst providing outright improvements to a vehicle’s off-road capabilities, an Air Locker also allows a 4WD to be driven in a more controlled manner, thus reducing the likelihood of vehicle damage and environmental impact.

Continually developed and enhanced over the past 20 years to maintain award-winning performance and reliability, over 100 Air Locker models are now available to suit a huge range of 2WD and 4WD applications.
