Development - To ensure we meet your expectations, ARB invests heavily in research and development. Our design and engineering team utilizes the latest CAD, CAM parametric modeling systems and finite element analysis packages, and is supported by subcontract companies and universities for special projects like vibration, strength and crash testing. With an air bag equipped vehicle for example, it is essential that the vehicle's crush rate and air bag triggering is not altered when a bull bar is installed. Our exhaustive testing programs ensure ARB bull bars meet these requirements. We also devote considerable time and resources toward to sourcing new products from around the world. IPF lights from Japan, Warn winches from the US' we scan the globe in search of equipment that meets both the demands of our customers and our own stringent quality requirements. What's more, we're also constantly on the lookout for new ways to improve our business practices, from distribution to customer service. ARB is a Quality Endorsed Company, and wherever we can, we endeavor to 'raise the bar'.

With our improved two piece design available right across the range, along with the addition of forged gears and an industry leading five year warranty, ARB Air Lockers are now better built and better backed than ever before. Created to provide 100 percent traction on demand, without sacrificing any of your vehicles highway driving performance, ARB Air Lockers employ a 12 volt ARB Air Compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flip of a switch and all within the comfort of the drivers seat. 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. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. In addition to providing outright improvements to a 4x4s off road capabilities, the Air Locker offers significant environmental benefits. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.
History - The origins of ARB can be traced back to Australia's remote Top End, circa 1975. A region of vast distances and rugged terrain, it was fast becoming a Mecca for the nation's burgeoning 4WD community. However, the very environment that attracted 4 wheelers also wreaked havoc on their equipment when driving in extreme conditions, only the best 4x4 accessories will do. This was the conclusion drawn by Tony Brown during his travels at the time. While exploring the treasures of the Top End, the skills Tony gained from working on his Land Rover were regularly called on to mend damaged bull bars and broken roof racks. Bar work back then was crude, not at all suited to overland touring, and through this experience an idea was born high quality equipment that met the vigorous demands of 4WD owners. Upon returning to Melbourne, Tony put theory into practice via the family garage, where he sought to address the product deficiencies he'd encountered. His vision called for a combination of sound design principles and reliable raw materials' a simple solution to an endemic problem. The concept was embraced when it hit the fledgling 4x4 market, and ARB the initials of Anthony Ronald Brown was founded. Today, ARB is Australia's largest manufacturer and distributor of 4x4 accessories. We also have an international presence, with an office in the US and an export network that extends through more than 80 countries around the globe. Our philosophy, however, has never wavered from its original course quality, reliability and practicality above all else.
