RockShox Reverb Stealth Air Valve Assembly

You likely need this part if your Reverb seatpost is failing to hold air pressure or if you notice the valve itself is damaged or leaking during a service interval. If your post sags or won't return to full extension despite being properly inflated, the valve assembly is often the culprit.

This specific assembly is designed for Reverb and Reverb Stealth dropper seatposts. However, because RockShox has released several generations of the Reverb, it is highly recommended to verify your specific seatpost model year or serial number against the part number 11.6818.014.000 before purchasing.

If you are comfortable performing a standard air service on your dropper post, you can install this yourself. You will need specific tools to disassemble the post and access the internal air chamber, so ensure you have the correct service manual for your specific Reverb generation on hand.

This assembly is the valve mechanism itself. While it typically comes ready to install, it is standard practice to replace any O-rings or seals you encounter during the disassembly process to ensure a complete, airtight seal.

Using genuine RockShox parts ensures the exact tolerances required for the high-pressure environment inside your seatpost. Aftermarket alternatives may not provide the same seal integrity, which can lead to premature failure or inconsistent performance on the trail.
