- FLOAT Air Spring
Inspired by the operation of Fox shocks, the small internal connection system between the negative and positive air chambers of the FLOAT system allows for automatic suspension compensation at all times, with perfect operational balance. The system self-adjusts by reducing the initial force required to activate the fork, resulting in a suspension that is much more sensitive to small terrain irregularities. The system's curve can be modified through internal spacers.

- FIT4
The patented Fox FIT4 (FOX Isolated Technology) closed cartridge system offers three selectable on-the-fly adjustment positions: Open, Medium, and Firm, to adapt to road conditions. In Open mode, Factory series forks have over 22 clicks of low-speed compression adjustment to perfectly tailor the damping response to the rider's preferences.
The FIT4 cartridge damper has been redesigned starting from the award-winning HSC/LSC damper to achieve a much more advanced damper compatible with all Fox forks. The result is increased sensitivity with the same support.
