MY27 Float X LiveValve Neo Factory Trunnion Shock

Fox MY27 Float X LiveValve Neo Factory is a piggyback, air-sprung rear shock built for modern all-mountain and trail bikes that need both traction on rough descents and efficient support when the pace picks up. Its LiveValve Neo system uses onboard sensors to react to terrain and rider inputs in real time, helping the bike stay composed through impacts while reducing unnecessary bob during hard pedaling efforts.

With a trunnion mount layout for contemporary frame fit and stiffness, the Float X platform pairs a pressure-balanced monotube design with a high-flow main piston to keep damping consistent on long, demanding runs. The Factory Series finish adds Kashima coating for smooth initial movement and durability where the shock sees constant contamination and wear.

Dialed advantages for aggressive trail riding

1. LiveValve Neo automatic damping control - Sensors continuously adjust shock behavior to balance pedaling efficiency with impact readiness when the trail turns rough
2. Piggyback reservoir + pressure-balanced monotube - Helps maintain damping consistency and control on extended descents where heat and repeated impacts can overwhelm lighter shock designs
3. Wide, rider-relevant adjustability - 2-position firm mode plus 11-click low-speed compression and 16-click low-speed rebound for precise support, traction, and recovery speed tuning
4. Large EVOL air chamber (max 350 psi) - Enables lower operating pressures for improved small-bump sensitivity while preserving a broad tuning range for different rider weights and leverage curves
5. Updated top-out and bottom-out bumpers - Refines end-stroke control and reduces harshness when the suspension reaches its limits
6. App-enabled setup and service management - Use the LiveValve app to select tunes (factory or custom), track rides, and set suspension service interval reminders from a smartphone

Note: mounting hardware and sensors are sold separately. Claimed weight is 669 g for the system including shock, sensors, and battery.
