The RockShox Charger 3.1 RC2 Crown Damper Upgrade Kit with ButterCups is the definitive upgrade for RockShox Pike C1+ (2023+) owners who want the most advanced damping available in the Pike platform. The Charger 3.1 RC2 adds independent high-speed and low-speed compression adjustment, while ButterCups target the high-frequency vibrations that conventional dampers miss entirely.

  • Charger 3.1 RC2 Crown — independent high-speed compression, low-speed compression, and rebound adjustment
  • ButterCups technology absorbs high-frequency trail buzz before it reaches the stanchion seals
  • Complete right-side internals for a full damper replacement
  • Crown-mounted configuration for Pike architecture
  • Fits Pike C1+ forks, 2023 model year and later

ButterCups are small compliant elements integrated into the top cap assembly that act as a high-frequency isolation system — they absorb the rapid, low-amplitude vibrations from trail texture and rough surfaces that a standard hydraulic damper cannot address. The result is a fork that feels more refined and communicative on high-speed rough terrain. Charger 3.1 RC2 then adds genuine high/low-speed compression independence for dialling in big-hit control separately from pedalling firmness.

This kit is specific to RockShox Pike C1+ forks (2023 and later). Confirm your Pike's model year and revision before ordering.
