MY27 DHX Factory Trunnion Shock

Fox MY27 DHX Factory Trunnion Shock is a gravity-focused coil rear shock built for consistent performance on long, rough descents. A piggyback reservoir helps manage heat and maintain damping control when runs get repetitive, while the Factory Series Kashima coating reduces friction for smoother small-bump response and more consistent feel through the stroke.

Key tuning advantages for demanding terrain

1. Trunnion mount layout - Supports modern frame packaging and leverage designs for precise shock fit and suspension kinematics
2. 2-position firm mode switch - Adds an on-the-fly firmer setting for transitions and smoother sections without losing the core coil feel
3. 11-click low-speed compression (LSC) - Fine-tunes support under braking, pumping, and corner loads
4. 16-click low-speed rebound (LSR) - Dials return speed for traction and control across different spring rates and trail speeds
5. Updated MCU bottom-out bumper - Increases end-of-stroke progressivity to reduce harsh bottom-outs on bigger impacts
6. Detented preload collar + improved top-out bumper - Makes preload adjustments more repeatable and keeps suspension action quieter at full extension

Note: Coil spring and mounting hardware are sold separately.
