• Enables a complete damper rebuild (oil + dynamic seals).
• Allows safe shaft clamping on both DHX shaft diameters.
• Provides accurate IFP depth reset after bleeding.
• Supports proper servicing without opening non-leaking components.

With basic hand tools and this kit, you can restore proper damping function at home without shop-only fixtures.

• FOX DHX RC2 (2010–2015)
• FOX DHX RC4 (2010–2015)
• Both 1/2" (≈12.7 mm) and 5/8" (≈15.8 mm) shaft versions

• Schrader valve core tool (mandatory).
• Essential non-printable tools used across damper service: Essential Tools .

• DHX Shaft Clamp (1/2" + 5/8") : choose the correct clamp based on your shaft diameter.
• Damper Body + Reservoir Clamp : optional, only required if the body or piggyback is leaking.
• IFP Depth Tool (Graduated) : precise and repeatable IFP height reset after bleeding.

• MTB Hydraulics – 1/2" shaft
• MTB Hydraulics – 5/8" shaft
• Anso – 1/2" shaft (includes valve core)
• Anso – 5/8" shaft (includes valve core)

IFP pressure: ~160 psi

Measure depth from the flat surface (not the raised rim):

• 10.500 × 3.500 → 1.100"
• 9.500 × 3.000 → 1.020"
• 8.750 × 2.750 → 0.980"
• 8.500 × 2.500 → 0.940"
• 7.875 × 2.250 → 0.900"
• 7.875 × 2.000 → 0.860"
• 7.500 × 2.000 → 0.860"

• Most issues come from dynamic seals or the IFP seal.
• Dead rebound is often caused by poor bleeding or incorrect IFP pressure.
• Do not unthread the piggyback unless it is leaking.
• Clean shafts with isopropyl alcohol and wrap with dry paper towel before clamping.
• Heat eyelets and Loctited parts before removal.

Follow the MTB Hydraulics method instead of FOX’s official manual. You don’t need to open the adjuster and the process is safer. Watch the rebuild video.
