RockShox Boxxer Fork Upper Tube

This upper tube is designed for RockShox Boxxer forks manufactured between 2013 and 2024+. Because compatibility can vary by specific model year and chassis design, we recommend checking your fork's serial number on the RockShox TrailHead app to confirm the exact part number required for your specific build.

Yes, this part is engineered specifically for the 38mm chassis found on modern Boxxer forks. However, always verify your fork's stanchion diameter before purchasing, as older Boxxer models utilized different diameters that are not interchangeable with this component.

While it is technically possible to replace a single stanchion if only one is damaged, it is generally recommended to replace them as a pair. Replacing both ensures that the wear patterns, friction levels, and structural integrity are perfectly matched, which helps maintain consistent suspension performance.

Installing an upper tube is a major service procedure that requires specialized tools, including a crown press, a torque wrench, and potentially a bushing sizing tool. If you do not have experience with suspension overhauls, we strongly recommend having a professional mechanic perform the installation to ensure safety and proper alignment.

If your stiction is caused by scratches, scoring, or worn-out coating on the stanchion surface, replacing the upper tube will absolutely restore smooth travel. If the issue persists after replacement, you may also need to service your seals, bushings, or damper fluid.
