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?.

ARBs Air Locker Differential Spreader is a professional automotive tool that no differential installer should be without. Most common Salisbury style axle assemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve the required carrier bearing pre-load during set-up. Stretching the housing casting (or pumpkin) open by sufficient enough force as to allow extra shim to be added to create the pre-load is the method that the OEM manufactures endorse, and most manufacture's have included special spreader sockets in the housing for exactly this purpose. Insufficient pre-load can result in bearing failure, or ring and pinion failure on any differential, and possible oil/air leakage issues in an Air Locker Differential. As a part of ARBs Air Locker Tools range of differential service/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.
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.
