Fox Boost Valve Assembly Service Kit

You should consider a service if you notice a loss of damping consistency, unusual noises, or if the shock feels less responsive than it did when new. If your suspension is bottoming out too easily or failing to hold its tune, replacing the internal seals and components in this kit is a standard first step to restoring performance.

No, this kit is specific to shocks utilizing the Boost Valve system. Before purchasing, verify your specific shock model and year to ensure compatibility, as Fox produces various internal configurations that are not interchangeable.

While this kit contains the necessary replacement parts, servicing a Boost Valve assembly requires specific tools and a high level of precision to avoid damaging the shock's internal surfaces. If you are not experienced with suspension maintenance or lack the proper tools, we recommend having a certified suspension technician perform the work.

Fox generally recommends a full service interval based on ride hours, typically every 100 to 125 hours of riding. If you ride in particularly muddy or dusty conditions, you may need to perform this maintenance more frequently to prevent premature wear.
