Fox Racing Shox 40 Grip X2 Cartridge Assembly 2025

The major innovation in Fox fork line lies in the hydraulics, with the introduction of the GRIP X2 damper, born from motocross experience and wich is a true flagship of the brand in terms of adjustability and performance. The GRIP X2 damper  allows the fork to stay higher in its travel and offers a high level of customization for compression and rebound settings. To achieve this, Fox reworked the internal parts of the cartridge, increasing the piston rod diameter from 8 mm to 10 mm, the base valve from 20 mm to 24 mm, and the valve stack from 7 shims in the previous version to 23 shims in this new generation, providing more customization options
