AIR SPRING VOLUME SPACERS
Changing volume spacers in FOX 34 Step-Cast forks is an easy 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 one or more spacers to increase
bottom out resistance. If you are not using full travel, then you could remove one or more spacers to
decrease bottom out resistance.
1. Remove the air cap.
2. Release all air pressure from the fork by depressing the Schrader valve.
FOX forks may contain high air pressures. Release ALL air pressure from the main air
chamber before disassembly. Failure to do so may result in parts or fluids ejecting
from the fork, which can cause SEVERE INJURY OR DEATH.
3. Carefully unthread the topcap from the fork with a 6-point chamfer-less 26 mm socket.
4. Pull up to remove the topcap assembly from the fork crown.
5. Slide the air volume spacer or spacers horizontally to install or remove them from the topcap.
Do not exceed the maximum number of volume spacers for your fork. This can
damage your fork. Find volume spacer information online at www.ridefox.com.
6. Reinstall the topcap assembly into the fork crown and tighten to 24.8 N•m (220 in-lb) with
a 6-point chamfer-less 26 mm socket.
7. Add air pressure to your desired setting using a FOX high-pressure pump. Set the sag according
to instructions online at www.ridefox.com.
