Fox Float/X/DPX2 Air Volume Tuning Kit

Changing volume spacers in a rear shock is an internal adjustment that allows you to change the amount of mid stroke and bottom out resistance. 

• If you have set your sag correctly and are using full travel (bottoming out) too easily, then you could install an additional spacer to increase bottom out resistance. 
• If you have set your sag correctly and are not using full travel, then you could remove a spacer to decrease bottom out resistance.
