MY27 DHX Live Valve Neo Factory Trunnion Rear Shock

Fox MY27 DHX Live Valve Neo Factory is a coil rear shock built for riders who want the traction and consistency of a coil spring with the on-demand support of Live Valve automation. Its piggyback reservoir manages heat on long, rough descents, while terrain and rider-input sensors adjust damping in real time to help the bike stay composed when it’s getting hit hard and stay efficient when the trail smooths out.

Built-in tuning range is handled with a 2-position firm mode switch, plus precise external damping control via 11-click low-speed compression and 16-click low-speed rebound. Factory Series details—including Kashima coating, a detented preload collar, and updated bumpers—make setup repeatable and improve ride feel through the full stroke, from quiet top-out to more controlled end-stroke progression. The trunnion mount format supports modern frame layouts (mounting hardware and sensors sold separately).

Dialed features for modern DH and gravity builds

1. Coil spring + piggyback reservoir - Consistent damping and traction under sustained descending and repeated impacts
2. Live Valve Technology - Sensors read terrain and rider inputs to automatically adjust the shock for better efficiency and control without constant lever changes
3. On-the-fly adjustability - 2-position firm mode, 11-click LSC, and 16-click LSR provide practical, repeatable tuning for rider preference and track conditions
4. Factory Series Kashima coating - Low-friction, durable finish for smoother action and consistent feel over long runs
5. Updated bumper system - Revised MCU bottom-out bumper adds end-stroke progressivity; improved top-out bumper reduces noise for quieter suspension action
6. Smartphone integration - Choose factory or custom tunes, track rides, and manage suspension service intervals through the Live Valve app
