WHY INSTALL AN ARB AIR LOCKER
An ARB Air Locker enhances traction by locking both wheels on an axle when activated, making it invaluable in challenging terrains like mud, snow, rocks, or sand. Its selectable engagement allows you to maintain control during normal everyday driving and activate the locker only when necessary. Furthermore, ARB's reputation for quality ensures durability and reliability in demanding conditions. Watch the video for more
FORGED GEARS
Strength, durability and resistance to fatigue in all Air Locker® components is paramount. With phenomenal forces being applied to the side and pinion gears within the differential, ARB has invested heavily in the application of forged gears, typically found in heavy duty commercial, race and agricultural transmissions. When combined with ARB’s patented ‘timed gear’ design, the resulting strength of the whole assembly is amplified.
TWO-PIECE DESIGN
Housing this superior internal gear train in a two-piece case brings further benefits. Machining a case from two-pieces instead of three results in a much higher dimensional accuracy of the finished assembly and has allowed ARB Engineers to improve the design of other elements, resulting in a reduction of moving parts, increased strength and a more responsive activation.
UNRIVALLED SUPPORT
For total peace of mind, all ARB Air Lockers® are backed by a comprehensive, five-year, unlimited miles warranty. Coupled with ARB’s extensive dealer network, you can be sure we’ll be there to support you in the unlikely event of an issue.

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.
