AIR SPRING VOLUME SPACERS
Changing volume spacers in Marzocchi BOMBER Z1 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.
Marzocchi 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 32 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.Marzocchi.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 32 mm socket.
7. Add air pressure to your desired setting using a high-pressure pump. Set the sag according to
instructions online at www.Marzocchi.com.
