Air Locker Destruction Test
In order to continually improve the product, our engineers are constantly trying to break Air Lockers. We even built a specialised 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.
Closer Look
The ARB Air Locker is a driver-controlled, selectable locking differential that provides ultimate traction on demand without sacrificing on-road driveability. When activated, it delivers equal drive to both wheels on an axle, allowing you to take full advantage of the available traction in all conditions.
Specifically engineered for your Nissan Navara D22's independent front suspension, this 27 spline, 8 bolt Air Locker (R180A) transforms its capability. A standard 'open' differential is a compromise, directing all power to the wheel with the least grip, leaving you stranded. The ARB Air Locker overcomes this by solidly locking the axle at the flick of a switch, providing 100% traction instantly to both front wheels.
This allows your Navara D22 to confidently tackle steep inclines, rocky obstacles, and slippery tracks. When disengaged, the Air Locker functions just like an open differential, maintaining safe and predictable handling on sealed surfaces. Built in Australia from high-strength, aerospace-grade materials, and backed by a 5-year warranty, the ARB Air Locker is the durable and reliable traction aid trusted by off-roaders globally for its proven performance in challenging Australian conditions.
