FOX 40 Factory GRIP X2 Fork

The FOX 40 Factory GRIP X2 Fork is FOX's flagship dual-crown downhill suspension fork, now updated with the revised GRIP X2 damper and FLOAT EVOL GlideCore air spring for increased tunability, traction, and control at speed.

Designed for aggressive downhill riding, the latest FOX 40 combines 203mm of travel with the stiff, precise 40 chassis, Kashima-coated upper tubes, lower-leg pressure bleeders, and a floating axle system. The new GlideCore air spring is designed to reduce binding under dynamic loads, helping the fork remain smooth and responsive as the chassis flexes through rough terrain.

The GRIP X2 damper provides extensive external adjustment for riders who want precise control over suspension feel and support. Together with FOX's updated air spring and proven dual-crown chassis, the new 40 Factory is built for riders looking for maximum downhill performance without unnecessary weight.
