ARB 4x4 Accessories Banner

Who is ARB?

ARB was founded by Tony Brown back in 1975. He was inspired by his offroading trip to Australia. And soon afterward, he decided to create a company that would provide quality offroad parts for various 4x4 vehicles. During those times, offroaders resort to homemade do-it-yourself parts that often fail during the trip.

The Australian outback is known for its harsh conditions like bumpy roads, extreme temperatures, which are punishing on the vehicles. Broken parts are a common occurrence and Tony decided he could do something better. Using his experience and know-how, he developed more durable equipment that would be able to handle any harsh condition. 

Starting in his small garage, he made his prototype, and from then on the rest is history. Today, ARB has become synonymous with 4x4 and offroading and has been the leading offroading brand in the world. They have become the largest offroad parts manufacturer with a presence in different parts of the globe.

Built with Only the Best

ARB heavily invests its resources in its research and development. The company uses the latest CAD, CAM modeling system that enables them to create and fine-tune its design down to the smallest detail. ARB also partners with some of the top brands in the world like IPF, WARN, and more. This allows them to create products that are unmatched when it comes to performance and quality.
