Faster Top-To-Bottom
The MY27 FOX 40 has been completely reworked from the damper to the air spring down to the lower leg. Every update has been driven by one goal: to create the fastest FOX 40 ever madeâboth on paper and on the track.
Gravity Gets The GlideCore Treatment
The next-generation GlideCore air spring introduces both vertical and horizontal compliance allowing the fork to better track rough terrain while reducing rider fatigue. Paired with an MCU bottom-out bumper and the updated GRIP X2 damper the 40 delivers improved support without sacrificing the supple feel riders expect from FOXâs flagship downhill fork.
New Grip X2 Damper
The biggest update is the entirely new mid valve piston and valve stack (AKA main piston assembly). FOX kept the same high-fidelity valve stack but updated shape of the valves. The shape of the ports in the piston are also different. These updates build upon GRIP X2âs already award-winning suppleness while preserving support without the harshness.
