Fox Suspension Float X Air Volume Spacer Tuning Kit

This kit is specifically designed for 2022 and newer Float X shocks, as well as the 2025 Float X Live Valve Neo. If your shock is an older model or a different series, these spacers will not fit.

Adding spacers reduces the air volume inside your shock, which makes the suspension more progressive. This means the shock will feel more supportive deeper in its travel and resist bottoming out on big hits or harsh landings.

No, you should only install one spacer at a time. The kit includes a range of sizes so you can experiment with different volumes to find the exact level of progression that suits your weight and riding style.

It is a straightforward process for a home mechanic with basic tools. You will need to deflate the shock, remove the air sleeve, snap the spacer onto the air piston, and reassemble, but always refer to the Fox service manual for your specific shock model to ensure safety.

If you are frequently bottoming out your shock even with the correct sag, start with a smaller spacer and test ride. If you still feel like you are blowing through your travel too easily, move up to the next size until you find the right balance of support and full travel usage.
