Upgrade your off-road suspension with hydraulic bump stops built to control harsh bottom-outs and protect your vehicle and occupants from high stress loads. Acting as a secondary shock during the last inches of compression, these bump stops progressively increase damping for maximum impact control at high speeds, on rough terrain, or when heavily laden.

Engineered for race-ready performance, the smooth, mirror-polished body is crafted from SSID alloy steel tubing with a clear cadmium finish for exceptional corrosion resistance. Velocity-sensitive valving automatically adapts to changing terrain to improve control, handling, and comfort, while Radflo’s exclusive Freeflo racing piston delivers adaptive damping you can tune to your driving style. Multi-stage compression and rebound characteristics are independently customizable, and every component is fully rebuildable, serviceable, and tunable for long-term reliability.

Designed for the harshest off-road conditions, the chrome-plated alloy steel rod and CNC-machined bronze rod guide ensure unyielding performance and reduced friction. A multi-direction, triple-lip sealing system maintains excellent gas and oil retention while preventing contamination. Choose the stroke length that best matches your mounting and performance requirements, and fine-tune valving as needed—either at home or through professional service.
