A relentless commitment to research and design, the use of quality materials, and an uncompromising approach to manufacturing have all contributed to the success of the Air Locker in over 100 countries worldwide.
Designed and manufactured in Australia, ARB Air Lockers will enhance the traction of your 4×4 in just about any terrain, whether it’s rock, clay, gravel, sand, snow, or mud.
Now with a state-of-the-art two-piece design available right across the range, forged gears for the ultimate in strength and durability, and an industry-leading five-year warranty, ARB Air Lockers are better backed and better built than ever before.
Strength, durability, and resistance to fatigue in all Air Locker components are paramount.
With phenomenal forces being applied to the side and pinion gears within the differential, ARB has heavily invested 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.
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.
