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.

BEST OF THE BEST

I am new to the off road scene. When researching for which compressor to go with for airing up, the only brand I saw over and over was ARB. I finally got this installed and it does not disappoint! Hands down a must for all off-roaders.

Great investment!

Definitely worth the investment! I was originally on the fence due to the cost, but it was a no brainer after I aired up that first time. My time was cut down by 75%! Highly recommend to anyone that's considering it. One of my best investments so far.
