34 Rhythm/Bomber Z2 Air Shaft FAQ

Which models of Fox and Marzocchi forks does this air shaft fit?

The Fox/Marzocchi Air Shaft for 34 Rhythm/Bomber Z2 fits all models of Fox 34 Rhythm and 2018 +Marzocchi Bomber Z2. Fox currently owns and manufactures Marzocchi products, and the Fox 34 Rhythm share the same chassis specs as the Marzocchi Bomber Z2.

This air shaft is NOT compatible with any other models of Fox or Marzocchi forks. It is NOT compatible with non-Rhythm models of the Fox 34 forks including Factory Series, Performance Series Elite, or Performance Series.

How do I properly install and lubricate this air shaft in my fork?

Below is the installation procedure we follow in our shop:

  • REMOVE THE AIR, remove the lower legs, and remove the current air spring.
  • Clean the inside of the air-side stanchion and lower legs like you normally would during a fork service.
  • On the new air shaft, carefully remove the upper piston seal, dip it in Fox 20wt Gold Oil, and reinstall it.
  • Place a dab of 20wt Gold on the top and bottom of the lower seal that slides on the shaft (base plate), and slide it back and forth to lubricate the lower seal.
  • Next, take a fingertip-sized dab of Slickoleum and dunk that finger into 20wt Gold Oil. Swab that mixture inside of the first few inches of the air-side stanchion. We do this about two times to accomodate for the 3cc's of factory recommended oil volume in the air chamber.
  • Install the new air shaft into the stanchion while depressing the air valve at the top of the stanchion to allow the air spring to slide in easily. The outer seal on the base plate wil now be lubricated when you insert the air shaft into the stanchion
  • Install the new snap ring, and you're all set. Reassemble the fork as you usually would during a normal fork service.

Will I need a new damper that matches the same length of travel as the new air shaft?

You do not need to pay any attention to your damper if you are changing the travel to be shorter than what it is now, because the damper will just compress to accomodate for the decreased travel. Yes, you can even decrease your 150mm fork all the way down to 100mm and your damper will simply compress to the new travel without any negative effects.

However, if you are extending the travel of your fork, then you need to check to ensure that you are not going above the maximum travel of your specific damper. Below is a list of the common dampers that fit in the Fox 34 Rhythm/Marzocchi Bomber Z1 chassis, along with their maximum travel according to the fork's wheel size:


Maximum Damper Travel (DO NOT EXCEED):

  • Fox 34 GRIP2 Damper Maximum Travel : 29" Fork = 140mm / 27.5" = 150mm
  • GRIP Damper Maximum Travel : 29" Fork = 140mm or 150mm depending on CSU model (must confirm with Fox) / 27.5" = 160mm
  • RAIL Damper Maximum Travel : 29" Fork = 150mm / 27.5" = 150mm
