RockShox BoXXer C1 Uppertube

No, this specific upper tube is designed exclusively for the BoXXer C1 model. It will not fit older BoXXer generations or other RockShox fork models, so please verify your specific fork version before purchasing.

No, this is a standalone replacement upper tube. It does not include the crown or steerer tube, so you will need to transfer those components or have them pressed in by a professional mechanic.

Replacing an upper tube requires specialized tools, such as a hydraulic press, to ensure the crown and steerer tube are seated correctly and safely. Unless you have the proper workshop equipment and experience, we strongly recommend having a professional mechanic perform the installation to avoid structural failure.

This specific upper tube is designed for the damper side of the fork. Ensure you are ordering the correct side, as the internal dimensions and threading are often specific to the damper assembly.

Using a factory-spec replacement ensures the exact tolerances required for your fork's seals and bushings to function correctly. Aftermarket parts often lack the precise finish and material specifications needed to maintain the BoXXer's intended damping performance and structural safety.
