Fox MY27 Float X Factory Rear Shock is a performance-focused air rear shock built for modern all-mountain and trail bikes that demand consistent damping on long descents and efficient support on the way back up. Its piggyback reservoir and pressure-balanced monotube design help maintain control when the shock is working hard, while the
Factory Series Kashima coating reduces friction for smoother small-bump sensitivity and more consistent feel through the travel.
Tuning range is broad and practical: a
2-position firm mode switch adds on-demand efficiency, while independent low-speed compression and rebound adjusters make it easy to match the shock to rider weight, leverage curve, and terrain. The
large EVOL air chamber supports lower operating pressures and a wider window of setup options, with a stated maximum of
350 psi. Updated top-out and bottom-out bumpers further refine feel at the ends of travel for better composure under repeated hits.
Key setup and ride advantages
- Piggyback Reservoir - Improves heat management for more consistent damping on long, rough descents
- Pressure-Balanced Monotube + High-Flow Main Piston - Delivers controlled support with improved oil flow for sustained performance under heavy use
- 2-Position Firm Mode Switch - Adds efficient pedaling support without giving up descending tune
- 11-Click LSC / 16-Click LSR Adjusters - Clear, repeatable tuning for traction, pop, and stability across changing terrain
- Large EVOL Air Chamber (Max 350 psi) - Enables lower pressures and a wide tuning range to dial in feel and support
- Factory Series Kashima Coating - Reduces stiction for smoother response, especially on small bumps and chatter
