Radflo Suspension

Model #5SB-003-00


Shopper Award

Our hydraulic bump stops are the perfect solution for vehicles that experience suspension bottoming at high speeds or when heavily laden. As the suspension reaches maximum compression, this secondary shock progressively increases damping resistance for maximum impact control. As a result, the vehicle and occupants are protected from high stress loads. Protects vehicle and driver from high stress loads caused by severe suspension impacts.

Radflo bump stops are engaged during the last few inches of compression travel to help cushion heavy impacts. When used correctly, they can significantly reduce dangerous stress loads that could otherwise harm the vehicle and driver.

Race ready construction and superior finish. Our hydraulic bump stops feature a smooth, mirror polished body manufactured from SSID steel tubing. Choose from 2.0 inch, 3.0 inch or 4.0 inches of stroke based on your performance and mounting requirements. A clear cadmium finish provides the highest level of corrosion resistance. Velocity sensitive valving automatically adjusts to terrain for improved control, handling and comfort.

Radflo's exclusive Freeflo racing piston utilizes adaptive damping technology to automatically match bump stop performance to surface conditions. Multi-stage compression and rebound damping characteristics can be independently customized to suit your vehicle setup and driving preferences.

Completely rebuildable, serviceable and tunable for virtually unlimited service life. We designed every single component to be easily serviced or replaced. Even the individual valve shims can be changed to fine-tune damping performance. Our highly experienced technicians can perform these services, or you can service the bump stops yourself for immediate results.

Exceptionally strong piston rod assembly designed for the harshest off-road racing conditions. Our chrome plated 1.25 inch alloy steel rod and slippery bronze rod guide provide unyielding performance in the roughest terrain. Multi-direction, triple lip sealing system prevents oil contamination while ensuring excellent gas and oil retention.

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.
