The Radflo 2.0 Air Shock with 1.25 shaft is the perfect solution for lightweight off-road builds looking to reduce suspension weight without sacrificing performance or control. Popular among rock crawlers and lightweight buggy applications, air shocks combine spring and damping functions into one compact, economical unit.

Similar to a coil-over in function, this air shock supports vehicle weight while controlling suspension motion. Spring rate and ride height are easily tuned by adjusting internal nitrogen pressure and oil volume, giving you flexibility without swapping springs.

Its ultra-compact size makes installation simple, even in tight mounting locations. Whether used as a primary suspension component or as a secondary spring carrier in more advanced setups, this 2.0 air shock delivers versatile performance at an economical price point.

Built with a mirror-polished SSID alloy steel body and clear cadmium plating for corrosion resistance, this shock is engineered for durability in harsh off-road environments. Radflos exclusive Freeflo Racing Piston and velocity sensitive valving automatically adapt to terrain conditions for improved handling and comfort.

Tech Insight

Air shocks are an excellent option for reducing unsprung weight while maintaining adjustable suspension performance. The 1.25 shaft increases structural strength while displacing additional fluid, helping balance durability and overall weight savings.

Spring rate and ride height are adjusted by modifying nitrogen pressure, typically starting around 200 PSI. This makes tuning simple without swapping coil springs. Radflos Freeflo Racing Piston and velocity sensitive valving automatically adjust damping characteristics based on shaft speed, providing improved traction and control across varied terrain.

Fully rebuildable and tunable, this air shock is designed for long-term serviceability and race proven reliability.
