THE SOLUTION

Created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, ARB Air Lockers employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flick of a switch, and all within the safety and comfort of the driver’s seat.

The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the 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 crown wheel, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional ‘open’ differential. In addition to providing outright improvements to a 4×4’s off road capabilities, the Air Locker offers significant environmental benefits. An Air Locker equipped truck can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

An ARB Air Locker® is Born

Ever wondered how a genuine ARB Air Locker® is manufactured? Wonder no more as we put you inside the machines that make the world’s best 4×4 traction aid, right here at our global headquarters in Melbourne, Australia.

 

Competition Use

Of the many ARB products seen in off-road competition, it’s the one you can’t see that makes the difference. ARB Air Lockers® continue to dominate the world’s toughest off-road events. Used by some of the biggest names in off-road competition, Air Lockers® are just as at home plugging through mud or scaling near-vertical rock ledges as they are on your daily pick-up. Competition drivers stake their reputations on quality and reliability. If they can trust Air Lockers® to get them across the finish line then you can be sure they’ll survive anything you throw at them off-road.

 

Air Locker Destruction Test

In order to continually improve the product, our engineers are constantly trying to break Air Lockers®. We even built a specialized test rig to allow us to place torques on the Air Locker® far in excess of what’s possible in the field. In this static torque failure test, we used a high performance Dana 44, 33 spline diff with the best axle shaft we could get our hands on to put the Air Locker® to the ultimate test.
