FOX Racing Shox

Mud Guard 40

What Our Gearhead® Experts Are Saying:

"I run the Fox Mud Guard 40 on my downhill build and the long profile makes a real difference on bike park days when the trails are running wet. The 4-point direct mount stays completely locked in through big hits and rough terrain, and the fit on the 40 is clean and precise right out of the box."

Bike park laps and downhill runs in wet conditions put serious demands on every component, and the Fox Racing Shox Mud Guard 40 is built to handle them without flinching. Designed specifically for the Fox 40 fork, this long-profile direct-mount fender locks securely to the fork lowers using a proprietary 4-point attachment system that stays put through the kind of high-impact, high-speed terrain that the Fox 40 is built for.

The long profile delivers maximum spray coverage for riders pushing hard through muddy tracks and wet bike park terrain, keeping mud and debris off the face and out of the line of sight when it matters most. Model year compatibility applies to 2025 and earlier Fox 40 forks from 2021 onward, so checking your fork serial number before purchasing ensures a clean, precise fit.
