This Radflo 2.0 Hydraulic Bump Stop and Short Bump Stop Can Kit provides a complete solution for adding controlled suspension bottom-out protection to your off-road build. Designed for rock crawlers, Ultra4 race cars, prerunners, and custom tube chassis vehicles, this kit combines Radflos race-proven hydraulic bump stops with precision laser-cut weld-on bump cans - all with a bundled price discount.

Radflo hydraulic bump stops act as a secondary shock absorber during the final inches of suspension compression. Using velocity-sensitive damping and Radflos exclusive Freeflo Racing Piston, they progressively increase resistance as suspension speed increasesabsorbing impact energy while protecting the chassis, suspension components, and driver from damaging loads.

Tech Insight

Hydraulic bump stops are critical for managing suspension compression during hard impacts. Instead of acting like a solid stop, they function as a progressive hydraulic damper that slows suspension movement in the final inches of travel. This dramatically reduces shock loads transmitted into the chassis and suspension components.

Radflo bump stops use velocity-sensitive valving combined with their Freeflo Racing Piston to automatically adjust damping based on impact speed. When paired with properly positioned bump cans, they provide a reliable and serviceable solution for protecting high-performance off-road suspension systems.
