40 – The Downhill Racer's Edge
Target Locked: Top of the Podium. Developed for this world's World Cup tracks, the FOX 40 has the Hot Seat in its sights. Thanks to its versatility and enormous traction, the Double Crown fork transforms into a true performance marvel in every DH race.
As a representative of the Factory series, this fork with the proven FLOAT air suspension is, of course, feature-rich. Technically, the Gravity-focused GRIP X2 damper particularly stands out, generating maximum traction and thus creating the confidence needed for racing. While the shape of the fork's arch and lowers intelligently increases stiffness to the maximum with minimal material use, the stanchion tubes impress with their smart detail solutions. Both the "Bypass" channels and the special bleed valves are dedicated to pressure management to exploit the suspension's maximum travel potential on one hand and to optimize the fork's response on the other. With its smooth and extremely durable Kashima coating, the 40 is also visually impressive.

GRIP X2 Greater Traction. Even more Control and Speed. When it comes to tuning, support, and plushness, this downhill-oriented damper stands out not only in the FOX lineup. Leveraging the advantages of long travel, GRIP X2 generates maximum ground contact and immense cornering traction. This not only combats fatigue but gives riders the confidence needed to push the limits in Downhill and Enduro races.
Lower Leg Arch To ensure an aggressive riding style even in Downhill use, the arch and lowers have a design that maximizes steering stiffness and stability. At the same time, any unnecessary additional weight has been avoided, to best meet both the highest requirements and performance demands.
Lower Leg Bypass Channels Air pressure increases during compression, which can prevent the fork from reaching its maximum travel. The channels in the lowers solve this problem by significantly increasing the air volume. This not only reduces the occurrence of unwanted pressure spikes but also allows oil to circulate into the upper areas of the lowers, keeping the internal seals and bushings constantly lubricated.
Lower Leg Bleeders To further improve sensitivity and responsiveness to small bumps, in addition to the "Bypass" channels, the lowers are equipped with bleed valves that allow equalizing atmospheric pressure with the simple press of a button.
Floating Axle The 20 mm floating through axle allows for frame alignment that avoids unwanted friction between the upper and lower fork legs. This ensures a smoother suspension movement throughout its entire travel.
