Now in its fourth generation, our patented FIT4 (FOX Isolated Technology) closed cartridge system provides three on-the-fly compression damping positions - Open, Medium, and Firm - to adapt to varying trail conditions. Factory Series forks feature an additional 22 clicks of low-speed compression adjust in the Open mode, allowing riders to fine-tune their exact damping preferences.

The FIT4 cartridge damper was redesigned based on our award-winning RC2 damper, resulting in a much higher performing damper across all forks.


To make maintenance easy, fun and enjoyable, provide the right tool for the job, and share our passion for biking with all riders.

We believe in giving riders the freedom to express themselves without constraints. Through tireless research and innovation, we produce tools that are durable, supremely efficient and highly innovative. By doing so, we provide riders with the best possible platform to get out there and ride!
