Fox Racing Suspension Oil

This oil is specifically formulated for use in Fox Racing Shox components that require a 4wt viscosity. Always check your specific fork or shock service manual to confirm the required oil weight before performing maintenance.

While it may function in other systems, it is best to use the oil weight and brand recommended by your suspension manufacturer. Using the wrong viscosity can significantly alter your damping characteristics and performance.

Fox generally recommends a full service, including an oil change, every 125 hours of ride time or once a year, whichever comes first. If you ride in muddy or dusty conditions, you may need to service your suspension more frequently to maintain optimal performance.

Yes, using the correct, high-quality suspension fluid like this 4wt oil is essential for reducing internal friction. It ensures your seals and bushings remain lubricated, which leads to a more responsive and supple ride.

This 4wt oil is primarily designed for use in the damper cartridge to manage rebound and compression. Refer to your specific service guide, as some Fox components require different types of fluid for the air spring chamber versus the damper.
