Description
Taking everything Vorsprung learned with the Corset air sleeves, the Luftkappe is a new air piston assembly that enlarges the negative air chamber to reduce the initial spring rate. This lets you run higher air pressure for more support in the middle and end of the stroke with improved sensitivity at the start of the stroke. User-installable and simple to set up, the Luftkappe transforms a good fork into a great fork.
Key Features
  • Coil-like feel without the harsh bottoming of a completely linear spring.
  • Lower initial spring rate increasing sensitivity.
  • Improved mid-stroke support & control.
  • Compatible with stock bottomless tokens.
  • Superior bump compliance and traction.
  • Reduced hand fatigue.
  • Reduces required compression damping.
  • Optional 10mm shaft clamps available for self-install.

Note: If your MY2018 36 Evol tops out noticeably, you will need to replace your air shaft assembly before purchasing the Luftkappe. For 2019 onwards, Fox have updated this part due to the topout issues that many of the 2018 36 Evol forks had. 34 forks do not have this issue.

Relevant Fox part numbers for the new air shaft assemblies, by travel:

180mm: 820-02-534-KIT
170mm: 820-02-535-KIT
160mm: 820-02-536-KIT
150mm: 820-02-537-KIT
140mm: 820-02-538-KIT
100mm (36 831): 820-02-539-KIT

If your fork does not have noticeable top-out issues, you don't need to replace the shaft before installing the Luftkappe.

Fox 36 (Float NA2 Evol) E-bike Specific [SPD-PED-ELEC]

Note that this fork usually requires the 34 Float NA2 Evol Luftkappe due to its thicker stanchions having a smaller ID.

Exceptions exist - eg Giant e-bikes, which still use the 36 Float NA2 Evol Luftkappe as they are standard 36s despite the e-bike stickers on the fork.
