Conquer harsh terrain with confidence. These off-road hydraulic bump stops deliver progressive, velocity-sensitive damping that engages in the final inches of suspension travel to control bottoming, cushion heavy impacts, and protect your vehicle and occupants from high stress loads at speed or under payload.

Built for race-ready performance and extreme durability, each unit features a smooth, mirror-polished body formed from SSID alloy steel tubing with a clear cadmium finish for maximum corrosion resistance. Radflo’s aluminum Freeflo racing piston uses adaptive damping technology to automatically match performance to changing surface conditions, enhancing control, handling, and comfort. Multi-stage compression and rebound characteristics can be independently tailored to your setup and driving style.

Serviceable, rebuildable, and tunable for a virtually unlimited service life, every component is designed for easy maintenance—down to individual valve shims for fine-tuning. Choose professional service from experienced technicians or handle routine service yourself for immediate results.

The piston rod assembly is engineered for the harshest off-road racing environments. A chrome-plated alloy steel rod, CNC-machined bronze rod guide with PTFE coating, and a multi-direction, triple-lip sealing system ensure excellent gas and oil retention while resisting contamination. Charged with nitrogen gas and filled with high-temp, foam-resistant suspension fluid, these bump stops provide consistent performance run after run.
