Β Fox/Marzocchi Forks Basic Damper Shaft Driver
This is our take to make a tool to drive the tip of the damper shaft into the lower legs for a lower leg service. We tried to make it as cheap as possible so we can sell it at a fair price, with the same efficiency as the real metal tools.
Β What It Does:
- Threads into the exposed rebound shaft (damper side) of Fox or Marzocchi forks
- Lets you tap out the lower leg without damaging the low-speed rebound meter rod or rebound internals.
- Plastic tip is safe, cheap, and replaceable if it wears out
- Helps avoid $200+ mistakes like cracked leaf springs, VVC internals or rebound meter rod.
- Works with a rubber mallet, block of wood, or gentle hammer
Compatible With:
Fox 34, 36, 38, and 40 mm forks (all years) : damper side only.
Equivalent to FOX part number
β οΈ Not compatible with taper-cast forks. A solution is coming : most users do not have this issue.

You can upgrade to the Deluxe Dual-Sided Driver, which includes:

- Same (Cross-compatible) replaceable tip system for the damper side
- Two-sided compact body, ideal for regular fork service
How To Use our tool:Β
- Release all the air in the fork
- Remove the rebound adjusters (2mm allen)Β
- Unscrew both the damper side nut and the air shaft side nuts with a long socket (10mm/15mm) and a ratchet.
- Remove the small plastic crush washer on each side if you can
- Thread the driver tip fully onto the rebound shaft until it bottoms on the inside shoulder of the tool (Don't screw too hard, the threads are plastic)
-
- If you don't thread it fully, the impact will not go on the inside flat and break the threads, which is not a big dealΒ and will still work but it's nice when the tool holds itself up.
- Hold the fork upright and gently strike the tool with a rubber mallet
- Do not hit on the center smaller shaft directly without the tool!!
- Also hit on the air shaft side but with a normal rubber mallet or a block of wood to protect it.
- Once the shafts breaks free, remove the lowers and proceed with cleaning
Extra Tips:
- Use Slickoleum inside your dust wipers, never Vaseline, it destroys seals
- Oil volume for bath oil is in mL = "cc"
Use a 60ml syringe or measuring cup - Check your forkβs oil volume here: Fox Oil Volume Chart (Velodrop)
- Use Fox Suspension Fluid 20wt or as specified by model
β οΈ Warning:
Do not hit directly on the rebound shaft tip, especially on GRIP2 or VVC forks.
You can damage the low-speed meter rod, break rebound leaf springs, or crack the mid-valve stack. This tool avoids all of that.

Β For shops and advanced users: if you're doing 10+ services, consider buying the real fox tool.
