FOX 38 Air Shaft FLOAT NA3
FOX 38 Air Shaft FLOAT NA3
SKU:820-02-749-KIT
Description
Fox is introducing the new generation of NA3 Glidecore air springs inside their new 38 forks. The NA3 air spring offers more consistent performance than the previous NA2 air spring through the use of elastomers, allowing the air spring to maintain its alignment as the fork flexes.
Fox’s new NA3 air spring uses a novel design with elastomers to increase performance while the fork is under load, and if you’re looking to modernise your previous generation Fox 36, upgrading to this new air spring is a great way to do it. Retaining suppleness while the fork is flexing noticeably increases the tracking ability of the Fox 38, helping you keep traction and control through all kinds of riding scenarios.

Fits 2027+ Fox 38 forks (not backwards compatible to forks spec'd with NA2).
