Air Locker gaining traction

ARB says its Air Locker has become the mainstay traction aid for 4WDers, dirt racers, rock crawlers and government agencies around the world.

ARB has now evolved the Air Locker design into an even more superior product with new features such as forged gears, timed gearing and a two piece design, along with launching a new logo and industry leading 5 year warranty.

Forged gears, which deliver increased load carrying capacity and strength, are typically found in the most demanding applications, including heavy duty industrial, commercial, race car and agricultural transmissions. In the Air Locker, the phenomenal amount of force applied to the gears means that their strength, durability and fatigue resistance is paramount, and so forged gears have been implemented across the range.

When combined with ARB’s patented ‘timed gear’ design, the resulting strength of the whole assembly is amplified. Simply put, timing the gears ensures that no matter when the Air Locker is activated, the gear teeth will always ‘lock’ into predetermined positions that offer the greatest surface area between the gear teeth. This ensures that optimal locking strength is achieved every time the Air Locker is activated.

ARB’s Air Locker division, based in Melbourne, utilises the latest arsenal of software programs, including Solidworks, CAD and Cosmos, in the development of all Air Lockers. The lengthy design process involves countless hours of testing using Finite Element Analysis (FEA), which allows the engineers to subject each Air Locker design to ‘virtual’ off road driving simulations which are impossible to replicate in the real world.

ARB Air Lockers are all manufactured in a world class, aerospace standard machine shop in Melbourne. Utilising aerospace grade materials and state of the art machinery, the facility ensures that the Air Locker maintains its reputation for quality, durability and reliability throughout the world. Backed by an industry leading five year warranty, the Air Locker is available for an extensive range of vehicle models, with over 100 applications.

Among the latest Air Locker applications are front and rear lockers for the Land Rover Discovery 3 and 4. Delivering traction on demand at the flick of a dash mounted switch, the Air Lockers allow owners to drive at a slower and more controlled pace, even in the harshest terrain.
