The RockShox SID RLC Charger Upgrade Kit is designed for riders who want to unlock the full potential of their SID suspension fork. Built around RockShox’s proven Charger damper technology, this upgrade kit delivers smoother, more controlled damping performance on rough trails and technical singletrack. By replacing the stock damper with a Charger unit, you gain more consistent support, better small-bump sensitivity, and improved control under hard braking or repeated hits, helping your front wheel track the ground with greater precision.
This kit is ideal for cross-country and marathon riders who demand race-ready performance without having to replace their entire fork. It is engineered to integrate seamlessly with compatible SID models, using RockShox’s established internal architecture and high-quality seals and fluids. The result is a fork that feels more refined, with easier-to-tune compression and rebound characteristics. Whether you are refreshing a well-used fork or upgrading a newer one, the RockShox SID RLC Charger Upgrade Kit offers a cost-effective way to modernize your suspension and gain a more confident, efficient ride.
