ARB Air Lockers & Accessories

Design & Engineering

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 alloy steel.

Recent developments have seen forged gears and an improved two piece design add increased strength and durability, whilst reducing the amount of moving parts to ensure precision amongst components and a much firmer and responsive activation. These additions have also resulted in increased load bearing capabilities.

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 wheel spin. 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.

For peace of mind, all ARB Air Lockers are backed by an industry leading five year warranty.
