In the late 1980s, two highly talented and spirited brothers from South Africa had a vision; to build a superior high performance shock absorber for professional motorsport applications. Their goals were simple. They would develop a more efficient shock design to outlast the competition. They would provide their customers with unparalleled service and support. And they would make the sport more affordable to racers by offering unbeatable prices.

That vision materialized in 1992 when Glenn and Warren Classen formed Radflo Suspension Technology. The Classen brothers were highly regarded for their skilled preparation and tuning of race suspensions, as well as their equally impressive knowledge of international business and finances. In no time at all, the brothers were prepared to release a selection of coil-over and smooth body shock absorbers for off-road racing applications.

By embracing unique applications and challenges that other shock manufacturers wouldn't consider, Radflo's reputation for versatility and effectiveness quickly transcended the motorsport industry. In 1994, the South African Defense Force turned to Radflo when it needed a dependable steering damper for its infamous Ratel, a ferocious 19-ton infantry fighting vehicle. This led to other industrial projects, including specialized damping units for the mining industry.

Meanwhile, Glenn and Warren's passion for professional motorsports remained paramount. By focusing their knowledge and experience on custom valving solutions, the brothers quickly established Radflo shock absorbers as the performance benchmark for all forms of competition. Off-road trucks, buggies, production cars, open wheel Formula Vee racers, and even motorcycles were winning races with Radflo shocks. The world's leading vehicle manufactures were also paying attention, as Nissan chose to equip their support vehicles with Radflo shocks for the trans-Africa Dakar Rally in 2003 and 2004.

To better serve the company's expanding international customer base, Radflo Suspension Technology relocated its operations to the USA in 2005. During the same year, a Nissan Super Production truck driven by Hannes Grobler won the South African Off Road Championship on Radflo shock absorbers. Proving that the accomplishment was by no means an accident, Grobler repeated this incredible feat in 2006 to become one of very few drivers to earn back-to-back SAORC victories.

In spite of the progress and worldwide achievements, Radflo Suspension Technology remains true to its original vision. This unrelenting attitude ensures the company will continue to provide racers and enthusiasts with superior products and unrivaled support at the best possible price.
