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?.

Air Locker locking differentials allow you to tackle the toughest terrain. As the worlds premier traction aid, ARB Air Lockers keep you moving in all conditions. While developing the Air Locker for the 2012 T6 Ranger and Mazda BT50, ARB Engineers noted the similarities between the differential dimensions with the Landrover Discovery Series 3. With the only difference being the ring gear diameter, this resulted in development of the RD217. This Air Locker fits the front axle of the Land Rover Discovery 3 and 4. The Air Locker for the rear axle followed. The RD218 was developed so that customers have the opportunity to lock both axles of their Discovery 3s. Because Discovery 3 are built with IRS systems, the removal and installation of the differential assembly consumes more time that a typical live axle vehicle. Furthermore, as the rear section of the exhaust system is mounted underneath the axles, it will need to be removed before carrying out the above. Adequate time should be allocated for RD218 fitting, but overall complexity level is relatively low. Due to variation between the rear axles of the Discovery 3 and 4, the RD218 only applicable for the Discovery 3. Please also note that it does not suit vehicles with an original equipment, O.E., differential locker.
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 4?4 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 4?4 market, and ARB ? the initials of Anthony Ronald Brown ? was founded. Today, ARB is Australia's largest manufacturer and distributor of 4?4 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.
