Compatibility

This is a damper service kit. It is not a complete shock, a universal air-sleeve service kit or a guarantee that every component required for a complete shock rebuild is included. Do not assume compatibility with DHX coil, DHX RC2/RC4, DHX2 or other FOX shocks based on similar names.
