The Story Behind Radflo Suspension

Radflo Suspension Technology was started in the 1980s in South Africa by two brothers named Glenn and Warren Classen. Their vision was to build a superior and more efficient high-performance shock absorber for professional motorsports that would outlast the competition.

The Classen brothers were highly regarded for their skilled preparation and tuning of race suspensions, in addition to their knowledge of international business. In no time, the duo was prepared to release a selection of coilovers and shock absorbers for off-road racing applications. Before they knew it, Radflo’s reputation for efficacy and versatility quickly transcended the motorsport industry. 

Widespread Demand for Quality Suspension

In 1994, the South African Defense Force turned to Radflo Suspension when it needed a dependable steering damper for its infamous Ratel, a huge 19-ton infantry fighting machine. This led to other industrial projects, including specialized damping units for the mining industry.

Through focusing their know-how on custom valving solutions, the brothers quickly established Radflo shock absorbers as the performance benchmark for all competition series. Off-road trucks, buggies, production cars, open-wheel Formula racers, and even motorcycles were winning races with Radflo shocks. The world's top automakers were also paying attention to the brothers’ success, as Nissan chose to equip its support vehicles with Radflo shocks for the trans-Africa Dakar Rally in 2003 and 2004.
