Airshock 2.5 Bypass – Radflo Suspension Technology

🔧 Maximum performance, total simplicity

The Radflo 2.5 Bypass Airshocks combine the simplicity of air shocks with the advanced performance of bypass dampers.

Designed for rock crawler, light buggy, and off-road proto applications, they handle:

✔ vehicle support (spring)
✔ damping
✔ bottom-out control

All in a compact and ultra-high-performance format.

⚙️ Integrated Bypass technology

Unlike a standard air shock, the Bypass version allows for precise suspension tuning via an external circuit.

Operation:

✔ Differentiated operating zones
✔ Rebound bypass
Allows for very firm rebound damping → avoids “bouncing/imbalance” issues

➡ Result: more progressive suspension that is much more effective on technical terrain.

💡 Air shock principle

Like all air shocks:

• Nitrogen pressure defines the spring rate
• Oil volume influences progressivity
• No coil spring required

➡ Ideal solution for lightweight vehicles and compact builds.

💪 Advantages

✔ Significant weight savings
✔ Simple and effective adjustments
✔ Compact format (saves space)
✔ Progressive behavior
✔ Ideal for rock crawling & trail riding
✔ Cost-effective alternative to coilovers
