Fox Rail Damper Basic Open Bath Service Guide

Basic service for FOX Rail and Rail 2.0 dampers, simple open bath design. Super reliable and easy to refresh at home.

Use this for 34 AWL, 36 AWL, Z1, Z2, and Marzocchi forks with Rail dampers (2020–2025+).

What's Included
  • GRIP damper body clamp (same size)
  • 10mm shaft clamp (for gently holding the shaft)
Oil Info
  • Use Fox 4wt or equivalent light damper oil
  • DO NOT overfill, these dampers can hydrolock
  • Always confirm the correct oil volume for your model
  • If unsure, check the table below or Fox documentation
References
Oil Volumes (Approx.)
  • Take quite a lot of oil compared to a normal cartridge style damper.Β 
  • Always over 125ml, so buy a big bottle.

If your fork isn’t listed, check Fox tech documents or reliable video guides.

Warnings
  • NEVER overfill,Β hydrolock will blow seals
  • These dampers are not pressurized (no IFP)
  • If damping disappears, it’s almost always low oil or base valve seal
Pro Tips
  • These dampers are extremely reliable, rarely need full rebuilds
  • Flush old oil/metal particles every 200h if riding hard
  • If compression feels weak β†’ replace base valve seal + new oil
  • If full rebound β†’ rebuild LSR
  • Always cycle the damper shaft slowly after filling, watch for bubbles
  • If compression vanishes after a few strokes β†’ you may be low on oil
  • If the shaft won’t compress at 70% travel β†’ you overfilled
  • Open bath = volume-critical, no self-bleed
