Volume tuning kits for Fox rear suspension. Changing volume spacers in your shock is an internal adjustment that allows you to change the amount of mid-stroke and bottom out resistance. If your sag is set properly on your bike but you're either using too much travel or not enough travel, then you could install the proper spacer to increase your shock's performance.

Specs:

• Compatible with 2013 or newer Fox Float CTD/DPS
• 9mm Shaft
