The ZEB Charger 3.1 RC2 Crown upgrade kit with ButterCups is a complete drop-in damper cartridge designed to upgrade your ZEB fork to the latest Charger 3.1 performance. It features a fully assembled right-side damper with refined compression range and improved small-bump sensitivity, providing better support and control across a wide range of terrain.

The Charger 3.1 damper offers truly independent adjustment of high-speed and low-speed compression, plus low-speed rebound, all with noticeable changes per click. Fitted ButterCups at the base of the damper absorb trail chatter and vibration, reducing hand fatigue and delivering a smoother, quieter ride.

This upgrade is ideal for enduro and e-MTB riders seeking better grip, increased comfort, and precise tuning—all in a quick and easy package.
