This pin socket interfaces with the rebound-side base valve adjuster on FOX DPX2 shocks.

• Allows clean removal of the rebound assembly
• Prevents damage to soft aluminum pins
• Maintains correct alignment during threading

Important: Do not use this tool on the compression side. That adjuster uses a different pin geometry and requires a separate tool.

Only if the rebound adjuster is leaking.

The rebound valve is not a normal service item and should be left untouched unless oil is leaking externally.

If the adjuster feels stuck:

• Soak with light penetrating oil (WD-40 is fine)
• Apply gentle heat
• Use slow, controlled torque
• Stop immediately if it resists

This pin socket is only part of the job. You will also need:

• Needle-style IFP fill adapter (mandatory for DPX2)
• Shock pump
• Valve core remover
• RockShox air fill adapter (FOX uses the same thread)
• Basic hand tools (Allen keys, wrenches)

If you don’t already own these, do not start the job.

This socket has no 3/8" drive.

Torque should be applied using a scale-based method, not a standard torque wrench.

• Use our luggage scale torque calculator
• Apply slow, even force only
• Over-torque can shear pins or crack the cap

For best control, pair this with our 2-Sided Zero-Play Pin Socket Wrench.

• This shock is pressurized in two places: air spring and damper
• Both must be fully depressurized before opening anything
• Use a proper needle IFP release technique
• Never open a damper under pressure

This tool is intended for experienced home mechanics only.
