RockShox Rear Shock Air Can Assembly

This assembly is specifically designed for RockShox Deluxe and Super Deluxe models (A1-B2 generations) from 2017 and newer. You should verify your shock's model year and series before purchasing, as internal dimensions and seal configurations vary significantly between generations.

Yes, this is a complete air can assembly, which typically includes the air sleeve and the pre-installed seals required to refresh the air spring system. It is intended to replace the entire outer housing to resolve air leaks or stiction issues.

If you have experience with suspension maintenance and the proper tools—such as a shock pump, strap wrench, and suspension-specific grease—it is a manageable task. However, if you are uncomfortable working with pressurized systems or lack the specific tools, a professional mechanic is recommended to ensure the seals are seated correctly and the shock is pressurized safely.

If your current shock is suffering from air leaks, inconsistent sag, or increased friction, replacing the air can assembly will restore the factory-level smoothness and support. It effectively resets the air spring system, which is often the most significant factor in how supple your rear suspension feels on the trail.

This specific assembly is compatible with shocks sized 185/210 with a stroke length between 47.5mm and 55mm. Always double-check the eye-to-eye length and stroke measurements printed on your existing shock body to ensure a match.
