DownSouth Motorsports » Radflo Suspension Technology

Founded in the 1980s by brothers Glenn and Warren Classen, RADFLO SUSPENSION TECHNOLOGY has grown from a small South African workshop into a global leader in premium damping solutions. Today the company’s Southern California headquarters designs, machines, and assembles an extensive range of monotube and remote-reservoir shocks in both OE-specific and universal lengths.

Radflo’s commitment to custom valving and exacting build quality quickly earned the brand a reputation as “The Choice of Champions.” Off-road trucks, buggies, Formula Vee cars, and even motorcycles have captured podiums on Radflo shocks, while OEMs such as Nissan relied on Radflo-equipped support vehicles to conquer the trans-Africa Dakar Rally. Beyond motorsport, Radflo’s engineering expertise has been tapped for military platforms—including the 19-ton Ratel infantry fighting vehicle—and for heavy-duty mining equipment.

Each Radflo damper features precision-machined components, race-inspired valving, and fully serviceable construction, allowing enthusiasts and professionals alike to fine-tune performance without compromise. From bolt-on 2.0″ coilovers for daily-driven pickups to massive 3.0″ bypass shocks for desert racers, Radflo continues to deliver superior products, unrivaled support, and exceptional value to clients around the world.
