FOX DHX Factory Trunnion shock, without spring
The FOX DHX Factory Trunnion is a rear coil shock for all-mountain and enduro riders who want maximum traction, sensitivity, and a reliable "coil" feel for both climbing and technical descents. The new monotube construction with a high-flow piston for the 2027 model year offers feedback and grip close to elite downhill shocks, but in a package optimized for all-day trail riding. An improved MCU bottom-out bumper ensures smooth travel at the end of the stroke, while the redesigned top-out bumper ensures quiet operation without unwanted noises.
Intuitive tool-free compression and rebound adjustment allow for quick fine-tuning of the shock according to the terrain and riding style. The two-position Open/Firm lever aids in efficient power transfer to the pedals when needed, and the indexed spring preload collar with lock prevents self-loosening of the setting. The shock uses a coil spring, which is sold separately – choosing the correct stiffness based on rider weight and frame specification is key to optimal SAG and suspension performance. The Trunnion mount and compatibility with bearing mounts on both sides simplify integration into modern frames.
The FOX DHX Factory shock is supplied without a spring, so it is important to check the mount compatibility and travel with your specific frame before purchasing to avoid damage during full compression. Regular servicing will help maintain the smooth operation of the new piston assembly and the long-term reliability of the shock.
