Fox Suspension 34 FIT4 Damper Assembly

This specific damper assembly is designed for 2020 Fox 34 series forks with 130-160mm of travel. Before purchasing, verify your fork's model year and travel length to ensure compatibility.

If you are comfortable performing standard suspension maintenance, such as lower leg services and cartridge swaps, you can likely install this yourself. However, it requires specific tools like a cassette tool and torque wrench, so consult the official Fox service manual before starting.

While a standard service replaces seals and oil, a full damper assembly replacement addresses internal wear that cannot be fixed with new seals. If your compression or rebound adjustments are no longer effective, replacing the entire cartridge is the most reliable way to restore factory-level performance.

This kit includes the damper assembly itself. You will typically need to purchase the appropriate suspension fluid and a seal kit separately to complete the installation and ensure the fork operates smoothly.

Yes, this damper assembly is compatible with 26-inch, 27.5-inch, and 29-inch wheel sizes, provided your fork chassis is a 34 series model from the 2020 model year.
