RockShox Charger Damper Upgrade Kit

This kit is designed specifically for RockShox BoXXer forks manufactured between 2010 and 2018 (models A1 through B2). It will not fit newer BoXXer models or other RockShox fork lines.

The extruded bladder design creates a sealed system that prevents air from mixing with the damping oil. This ensures consistent damping performance during long, rough descents where heat buildup would otherwise cause performance fade.

Once installed, you gain three distinct settings: an Open mode with adjustable low-speed compression for technical terrain, a Pedal mode for efficiency, and a firm Lockout mode for climbing stability.

Yes, you can expect a noticeable reduction in weight. This upgrade is approximately 100 grams lighter than the previous damper version, which helps reduce unsprung mass for better suspension sensitivity.

While the installation is straightforward for someone comfortable with basic suspension service, it does require specific tools like a cassette tool or socket for the top cap, a torque wrench, and fresh suspension oil. If you are not familiar with fork internals, we recommend having a professional mechanic perform the swap.
