The Ultimate Downhill Racing Fork
The Fox 40 Float Factory Fork is precision-engineered for downhill racing at the highest level. Built in the crucible of World Cup competition, this fork delivers unparalleled performance, stiffness, and control to dominate the gnarliest descents. With the latest GRIP X2 Damper, advanced floating axle technology, and a host of race-ready features, the Fox 40 is the definitive edge for downhill racers pushing the limits of their sport.

Key Features

GRIP X2 Damper
The GRIP X2 is Fox's most tunable, descent-focused damper ever created. Riders benefit from a higher ride position in the travel for increased traction and better cornering. With fully adjustable high/low-speed compression and rebound damping, it ensures confidence, reduced fatigue, and unrivaled control on steep, technical terrain.

Lower Leg Bleeders and Bypass Channels
Integrated bleeders equalize atmospheric pressure at the push of a button, ensuring consistent fork performance. Bypass channels increase volume, alleviating pressure ramping for smoother suspension action and better small bump sensitivity.

Floating Axle Technology
The 40's floating thru-axle aligns the chassis perfectly, reducing unwanted friction between the upper and lower fork legs. This innovation results in smoother suspension movement throughout the entire range of travel.

Lightweight, Durable Design
The lower leg arch maximizes stiffness and steering precision without adding unnecessary weight, making it perfect for demanding downhill races.

Kashima Coating
The Factory Series Kashima Coat delivers ultra-smooth, durable performance with minimal friction, ensuring top-notch responsiveness and longevity.
