The origins of ARB go back to 1975, when company founder, Tony Brown, was inspired by a 4WDing trip through the top end of Australia.

Back then, 4WDers relied on homemade or ill-fitting equipment that was not designed for extensive Outback expeditions. Endless corrugated roads, extreme temperatures, and the heavy loads carried by Australian travellers were tremendously punishing on vehicles that regularly tackled these kinds of conditions. Tony’s many years spent toiling on his Series 1 Land Rover proved extremely beneficial to others in the top end during his travels.

Damaged bull bars and broken roof racks ensured Tony’s expertise was regularly called upon, and through this experience an idea was born – well engineered, durable equipment that would meet the vigorous demands of 4WD owners. Upon his return to Melbourne, Tony put theory into practise, and began working in the family garage to address some of the product deficiencies he’d encountered on his trip. It was exactly what Australian 4WDers had been waiting for, and ARB, the initials of Anthony Ronald Brown, was founded. Today, ARB is Australia’s largest manufacturer and distributor of 4×4 accessories.
