ARB AIR LOCKERS

ARBs relentless commitment to research and design, the use of quality materials, and an uncompromising approach to manufacturing have all contributed to their success in over 100 countries worldwide. Designed and manufactured in Australia, ARB Air Lockers will enhance the traction of your vehicle in just about any terrain, whether on 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 built and better backed than ever before.

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 ARBs patented timed gear design, the resulting strength of the whole assembly is amplified.

Two Piece Carrier Design

ARBs internal gear train is in a two-piece Housing. 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.
