FOX Racing Shox

Mud Guard 40

What Our Gearhead® Experts Are Saying:

"The Fox Mud Guard 40 is exactly what a downhill and bike park fork needs in wet conditions. The 4-point direct mount holds firm through the kind of high-impact terrain the 40 is designed for, and the long profile gives you genuine full-coverage protection rather than the token splash guard you get with shorter options. Verify your model year with the fork serial number before ordering and this is a straightforward, high-value addition to any Fox 40 build."

The Fox 40 is built for the most demanding downhill and bike park terrain on the planet, and the Fox Racing Shox Mud Guard 40 is the factory-engineered fender solution that matches that standard. Designed exclusively for the Fox 40 fork, it mounts via a proprietary 4-point direct attachment system that distributes load evenly across the fork lowers, delivering the kind of locked-in stability that holds firm through high-speed hits, rough brake bumps, and sustained wet and muddy conditions.

The long profile is the right choice for Fox 40 applications, providing maximum spray coverage across the front wheel arc on the kind of high-volume, high-speed terrain that defines downhill and enduro race tracks. Where shorter fenders leave gaps in coverage on fast and muddy descents, the long guard keeps mud, debris, and spray consistently clear of the rider's face and vision through full runs.

Compatibility is specific to Fox 40 forks from model year 2021 through 2025. Verifying the fork serial number before purchasing confirms correct fitment and ensures the guard integrates cleanly with the fork's existing mount points without modification.
