The RockShox Charger 2.1 RC2 Damper Upgrade Kit brings independent high and low speed compression adjustment to BoXXer forks, giving riders precise control over damping feel on rough descents. Built around the Charger 2.1 RC2 platform, this kit suits 2010 and newer BoXXer forks, including the 27.5 and 29 inch C1 through C2 models produced between 2019 and 2023.
This upgrade kit includes complete right-side internals for straightforward installation into a compatible fork. The Charger 2.1 RC2 damper allows the fork to ride higher in its travel under compression, keeping the tires planted on the ground for improved control through chunky terrain and repeated impacts.
