RockShox Damper Shaft

This shaft is specifically designed for Deluxe RL/RT (B1), Deluxe Select (C1-C2), and Deluxe Select Plus (B2-C2) models from 2023 and later. You should verify your shock's specific model year and tune code, usually found on the air can sticker, to ensure it matches these compatibility requirements.

Replacing a damper shaft requires specialized tools, including a shock pump, internal snap ring pliers, and a shaft clamp, as well as the ability to bleed the damper system. If you are comfortable performing a full air can service and damper bleed, this is a straightforward replacement; otherwise, it is best handled by a professional mechanic.

Not necessarily. While a worn shaft can contribute to seal failure, oil leaks are most commonly caused by worn or damaged internal O-rings and wiper seals. If your shock is leaking, you should first attempt a standard seal kit service before assuming the shaft itself needs replacement.

You should replace the shaft if you notice visible scratches, scoring, or pitting on the stanchion surface, as these imperfections will tear through new seals and cause persistent oil leaks. Additionally, if the shaft is bent or shows signs of structural fatigue, it must be replaced to ensure safe operation and consistent damping.

No, this is the bare damper shaft component only. You will need to purchase a separate service kit that includes the appropriate O-rings, glide rings, and seals for your specific shock model to complete the rebuild.
