The Vorsprung Luftkappe Upgrade Kit transforms the ride quality of Fox 36 forks equipped with the 2015–2017 NA2 air spring system. By increasing the negative air chamber volume, the Luftkappe softens the initial stroke while improving mid-stroke support, offering better small-bump sensitivity and overall control. It delivers a smoother, coil-like feel without compromising bottom-out resistance or requiring major damper changes.

Features:

• Enlarged negative air chamber for reduced breakaway force

• Improved small-bump compliance and mid-stroke support

• Coil-like ride feel with more support and control

• Compatible with stock volume spacers

• Less reliance on compression damping for support

• Can be installed by experienced users with appropriate tools

Compatibility:
Compatible with Fox 36 forks using the NA2 air spring system from model years 2015–2017. To confirm fitment, use the Vorsprung Compatibility Checker.

Installation Notes:
Self-installation is only recommended for individuals with the required suspension service knowledge and tools. See the Vorsprung Installation Guides.
