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.
