The RockShox Charger 3.1 RC2 Crown Damper Upgrade Kit with ButterCups is the premium damping upgrade for the ZEB A1+ (2021+). The ZEB is RockShox's big-travel enduro and e-MTB fork, and this kit brings Charger 3.1 RC2 damping — with independent high and low-speed compression control — plus ButterCups to reduce high-frequency fatigue on rough, high-speed enduro terrain.

  • 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 ZEB architecture
  • Fits ZEB A1+ forks, 2021 model year and later

The ZEB platform runs 38mm stanchions and is designed for 150-190mm travel applications where big-hit control and long-day durability matter most. Charger 3.1 RC2 gives you independent high-speed and low-speed compression dials to manage both rough terrain impacts and pedalling efficiency separately. ButterCups add a further layer of refinement, absorbing the high-frequency buzz that conventional dampers pass through to the rider.

This kit is specific to RockShox ZEB A1+ forks (2021 and later). Confirm your ZEB's model year and revision before ordering.
