FOX GRIP X shock absorber cartridge (2027)
The complete original FOX GRIP X cartridge for the 2027 model year is a top upgrade and replacement part for FOX all-mountain and enduro forks. The closed-back damping system is delivered fully assembled, filled and bled, so it is ready for direct installation into the right fork leg without the need for further assembly.
Three-way independent damping adjustment – low-speed rebound (LSR), high-speed compression (HSC) and low-speed compression (LSC) – allows you to fine-tune the fork's behavior from big impacts to technical root-filled sections. The integrated Firm Mode in the extreme position of the HSC controller firmly closes the fork for efficient pedaling, while the safety blow-off valve immediately opens it in the event of an unexpected hard impact, protecting both the rider and the bike structure. The cartridge uses high-quality aluminum alloy and sealing components for high rigidity, reliability and stable damping even on long descents.
When replacing the cartridge, it is recommended to use new original FOX lower oil according to the lubrication chart of the specific fork and replace the crushing pads on the lower legs. Before purchasing, it is essential to verify compatibility using the 4-digit ID code on the back of the lower legs, as the cartridge is designed for a specific inner leg diameter and stroke. Installation requires advanced mechanical skills, special tools for cassettes/topcaps, and adherence to correct tightening torques.
