At the heart of the latest 40 is the updated GRIP X2 damper, featuring a completely new mid valve piston and revised valve stack design to improve support without adding harshness. The result is a fork that feels more composed under heavy loads while still delivering the supple, controlled feel riders expect from FOX’s top level downhill platform. Paired with the next generation GlideCore air spring, which introduces both vertical and horizontal compliance, the fork tracks rough terrain more effectively and helps reduce rider fatigue through repeated hits and demanding race stages.
The redesigned lower leg assembly further improves the package, using a generative design approach to optimise stiffness, strength and weight for modern gravity demands. Updated bleeders, relocated bypass channels and the new mudguard system all add to the fork’s refined real world performance and usability, while the splined cassette tool top cap makes setup and servicing more straightforward. With 203mm of travel, DH Boost 20mm floating axle spacing, 52mm offset and clearance for up to 2.5 inch tyres, the FOX 40 Factory GRIP X2 is built to deliver maximum downhill speed, control and confidence on the toughest tracks.
