A relentless commitment to research and design, the use of quality materials, and an uncompromising approach to manufacturing have all contributed to the Air Locker’s success in over 100 countries worldwide. The patented design of the ARB Air Locker is extremely strong, with structural components manufactured from aerospace grades of high alloy steel.

The design process of an Air Locker involves countless hours of testing. Computerised Finite Element Analysis (FEA) allows the designer to subject each Air Locker design to ‘virtual’ off road driving stress simulations much more extreme than those experienced in real life, including extreme temperatures and harsh wheelspin. Prototypes are tested to ensure the strength of the Air Locker exceeds that of the axles or other driveline components. Finally, field testing is carried out with units being fitted to 4WDs that operate in the harshest environments imaginable. Once this exhaustive design phase is complete, Air Lockers are manufactured in Australia by ARB, and sold throughout the world.

Features:

Air Lockers give you the traction you need, when you need it, all at the flick of a switch.

Provides 100% traction on demand without affecting on-road drivability or driveline wear

Vastly improved traction means less reliance on momentum, thus reducing the likelihood of vehicle damage and environmental impact

Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver’s seat

Ultra durable and extremely strong – only the highest quality materials used in construction

Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability

Thoroughly tested and proven design – trusted and used in over 100 countries around the world

Front and rear Air Lockers available for most makes and models

4WD and 2WD applications

Easy installation and maintenance – no special tools, skills or additives required

Two year warranty guarantees the Air Locker will be free of defects in materials

[tab title="Performance"]

A number of high performance models are available for specialist applications such as drag racing, competition rock crawling and heavy tank-track type snow equipment.

Designing locking differentials for applications such as these presented our engineering team with some significant challenges. Not only did the locker have to be able to withstand more traction torque than a standard differential, but it had to also tolerate massive amounts of torque handling facilitated by the substitution of custom made high alloy aftermarket axle shafts, which are cut with larger than standard diameter splines. This was particularly difficult owing to size constraints dictated by the original axle assembly. ARB met this challenge using a combination of aerospace grade materials, and a design guided by the results of high torque testing using computer simulations and destructive testing.
