A piece of Differential History has just come out of our Landcruiser Trakka Troopy - Learn more below:

Originally known as 'The Roberts Diff Lock' after the inventor Tony Roberts, it was renamed the ARB Air Locker in 1988. Tony Roberts' background lay in aircraft engineering and he was an avid recreational 4WD enthusiast who started working on the concept back in the early to mid 1980s. Its development process began with the Air Locker being vacuum operated with subsequent me<span class="text_exposed_show">chanisms being trialed. The final prototype was based on compressed air operation and has evolved from incorporating only five applications to well over one hundred.</span>​

Today the ARB Air Locker is sold in more than 80 countries worldwide and has a strong reputation for its quality and dependability. What gives it this standing within the market place is its proven, reliable, patented design, with structural components made from high grade alloy steel contributing to its tested superior strength. The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. </div>
