What customers say
This volume spacer kit is highly praised for significantly improving rear suspension performance. Riders consistently note the straightforward installation process, allowing easy customization of shock progression. The core benefit is enhanced bottom out resistance, enabling lower air pressures for better small bump sensitivity without losing support on big impacts. Users report a more controlled and predictable feel, boosting confidence on aggressive trails. The kit effectively tailors the air spring curve to individual riding styles and bike kinematics. This ability to precisely tune the shock behavior is seen as an essential, inexpensive upgrade for unlocking the full potential of the Float X or DPX2 shock, delivering a tangible improvement in ride dynamics.
Know before you buy
Volume spacers change the air spring curve of your shock. Adding spacers reduces the internal air volume, which makes the shock more progressive and harder to bottom out, while removing them makes the shock feel more linear and supple.
No, this specific kit is designed exclusively for Fox Float X and DPX2 rear shocks. They will not fit other models like the Float DPS or DHX series.
If you are frequently bottoming out your shock even with the correct sag, you should add a spacer to increase bottom-out resistance. If you find you cannot use the full travel of your shock despite hitting big features, you may want to remove a spacer.
You will need basic tools to remove the air sleeve from your shock, such as a shock pump, a strap wrench, and potentially a pick tool to remove the existing spacer. Always ensure you release all air pressure from the shock before attempting to open the air sleeve.
Yes, you can use multiple spacers to achieve your desired level of progression. However, always check the manufacturer's documentation for your specific shock model to ensure you do not exceed the maximum allowable number of spacers.
