RockShox Damper Shaft for Deluxe Select+ C1

No, this specific assembly is engineered exclusively for the C1 version of the Deluxe Select+ rear shock, produced in 2023 and later. It will not fit older shock generations, so please verify your shock's model year and version before purchasing.

This assembly includes the core components: the shaft, the damper rod, and the lockout piston. While it covers the primary mechanical elements, you will still need to source the appropriate seal kits, damper oil, and specialized suspension tools to complete the service.

This part is specifically designed for shocks with a stroke length between 37.5 mm and 45 mm. Using it on a shock outside of this range will likely result in improper damping performance or potential damage to the internal components.

You should consider a replacement if you notice visible scoring, scratches, or pitting on the shaft surface, which can cause oil leaks and seal failure. Additionally, if you experience inconsistent damping or a loss of lockout function that persists after a standard seal service, the internal rod or piston may be worn.

Yes, performing a damper shaft replacement requires specific suspension tools, including a shaft clamp, a torque wrench, and potentially a vacuum bleeder for the damper oil. Because this is a precision component, we recommend having the proper service manual for your specific shock model on hand.
