Make a good fork a great fork.

Introducing the Luftkappe air piston kit for:

  • Fox 34, 36 & 38
  • Rockshox Pike, Yari and Lyrik Solo Air forks
  • Rockshox Zeb

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.


  • 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

All Luftkappes are considered an easy-medium difficulty to install. If you've rebuilt forks before - they're a walk in the park.

Luftkappes do NOT come with the installation tools.


"The Luftkappe's change to the feel of the Lyrik was immediately noticeable on the trail. Traction was increased across chatter and the fork remained higher in its travel and more stable, improving the dynamic ride height without sacrificing the top end. My confidence soared when hitting sections with a lot of chatter and mid to large-sized hits, and the result meant more comfort and speed through such sections."

Vital MTB:

The Luftkappe blends sensitive small-bump compliance, mid-stroke support, and bottom-out resistance perfectly; pretty close to the holy grail of suspension performance - as good as the stock fork is, we no longer want to be without the Luftkappe.

Key things to note before you start (from the installation manual):

  1. You need a torque wrench. Don’t try it without one. Beg, borrow, rent, buy or steal one from a friend.
  2. You will need 10mm shaft clamps to hold the air spring shaft. Please don’t try grabbing the shaft in a vice or in V-blocks, you WILL
    damage it.
  3. We refer to the Rockshox service manuals for all aspects of the servicing OTHER than the specific installation of the Luftkappe to the
    Debonair Air Shaft.
  4. Record your air pressure and rebound settings before you start doing anything else.
  5. Don’t do it drunk. Even if you’re Australian.
  6. The Luftkappe only replaces the piston - not the entire air shaft. We will be removing the existing piston from the air shaft, and
    replacing it with the Luftkappe.
