Cheap and reliable seal kits from MTB-Hydraulics:

• 2016–2017 DHX2 Routine Kit
• 2018–2020 DHX2 Routine Kit

Includes all seals needed and often ships via untracked mail for only a few dollars.

Do not open the piston nut, this is a common cause of shaft damage. Instead, remove the sealhead from the eyelet side (only possible with the O-ring style sealhead from the MTB-Hydraulics kit). If you’re using the official FOX kit, you’ll typically need to use the bullet tool from the piston side.

• Shaft Clamp (2016–2020 only)
• Graduated IFP Depth Tool
• Bullet Tool for Fox DHX2 / Float X2 (2016–2020)

The shaft may still be usable. If enough thread remains, you can install a thin-profile 1/4-28 nut with red Loctite. Any industrial hardware store should have it (usually around $1).

If the break is too low, you’ll need a new shaft. Use this link to find the correct replacement (choose carefully): X2 9mm Shaft Search

• All Years DHX2 Clamp (2016+)
• Trunnion Torque Tool (for M10 trunnion bolts)

• Bench vise
• Knipex 10" pliers (recommended)
• Adjustable wrench (only if the sealhead is not overtightened)
• Shock oil + compatible DHX2 seal kit
• Torque wrench or luggage scale
• Foot pump with balloon fitting (to eject the IFP)

See our Essential Tools page for these.

Use a compressor on the bleed port (after draining oil), or use a foot pump with a balloon adapter and tape to blow the IFP out from the reservoir. Cover it with a rag, it can eject fast.

• Depressurize the damper before opening
• Open the bleed port slowly to release trapped pressure
• Use the IFP Depth Tool guide to set depth accurately
