RockShox Rear Shock Air Can Assembly

This assembly is specifically designed for RockShox Deluxe and Super Deluxe shocks from the A1 through B2 generations (2017 and newer). Before purchasing, verify your shock's model year and generation to ensure a proper fit, as internal dimensions vary significantly between different shock series.

Yes, this air can assembly typically comes with the essential seals and O-rings pre-installed or included to ensure an airtight fit. However, it is always best practice to use fresh suspension grease during installation to ensure the seals seat correctly and perform smoothly.

If you are comfortable performing routine suspension service, you can install this yourself with basic tools like a strap wrench, shock pump, and the correct suspension fluid. If you are unfamiliar with pressurized suspension systems or do not have the proper tools, we recommend having a certified mechanic perform the installation to avoid damaging the seals.

Replacing the entire air can assembly is often necessary if the inner surface of the can has become scratched or scored, which can cause air leaks that new seals alone cannot fix. It is a more comprehensive solution for restoring air pressure retention and suspension travel when the original housing has worn down.

Because this is a direct replacement part designed to match the original specifications of your shock, it should not alter the suspension's intended feel or progression. It is designed to return your shock to its factory-fresh performance rather than modify its characteristics.
