FOX DPX2 Full DIY Rebuild Toolkit

This toolkit includes all the critical tools you need to rebuild your FOX DPX2 shock at home safely, correctly, and with the right fit for the job. Built for serious home mechanics, it covers everything needed for a proper IFP reset and damper bleed. The DPX2 uses a needle-style IFP system and can be tricky, so this kit ensures you’re not improvising with the wrong tools.

Fox uses a lot of chamferless sockets for this rebuild, but it can all be done with normal wrenches. Just make sure to torque properly using the luggage scale method. We don’t include the chamferless sockets because they're not durable enough for sale and add unnecessary cost. We're keeping it lean and effective.

 What’s Included

• 1/2" Shaft Clamp (for the main shaft)
• Metal Pellet Retainer Tool (plastic version is too weak for DPX2)
• IFP Depth Tool (for setting 1.5" depth)
• Optional: DPX2 Rebound Adjuster Pin Socket

 Pellet Retainer Tip: You can make one yourself with a Dremel and a 4mm Allen key. DIY is cheap and works well!

⚠️ Safety & High Pressure Warning

This shock is pressurized in two places, the air can and the damper body. You must release both before opening anything.

• Release air spring pressure using the shock pump bleed button. Just do it 25psi at a time and pull on the shock after each drop in pressure to equalize the chambers.
  • If you go too fast and you can't pull the shock as it's getting sucked down, just add air again in the shock until you can pull it and equalize the chambers.
• Use the Needle Fill Tool to release damper pressure

A plastic ball is press-fit into the piggyback fill port. Remove it before doing the rebuild:

• Drill a shallow hole, do not go deep
• Hook with a pick and pull out
• The small hole in the middle of the piggy back screw is where you will use your Needle Fill Tool to release the pressure in the damper and to pressurize it after the rebuild.

• Never skip these steps. The IFP can shoot out violently if pressurized.
• IFP Pressure: 150 psi
• IFP Depth: 1.5 inches

 Bleeding Tips

• Use the glove method to push oil from the piggy back to the top of the damper shaft
• Both Rebound and Compression Circuits are connected right now so oil will just go up the center of the shaft as a whole.
  
• You can do a syringe Bleed from the damper side bleed port, just use the proper fitting from a break bleed kit. Doesn't work from the IFP port as it's the very small Fox fitting. We are working on a solution for a double syringe bleed.

DPX2 has two pellet ports: one in the eyelet and one in the piggyback. Use the piggyback one for all service. The one on the damper shaft is for non-piggyback shockslike the DPS, fox reuse the same damper tube.

 A Note on Adjusters

The rebound pin socket is only needed if the adjuster is leaking. Don’t open it unless necessary. We’re working on a compression tool too, but it’s not ready yet due to tricky geometry.

 Trunnion Mount Warning

If your shock is trunnion-mounted, use the Trunnion Shock Vise Holder. It prevents destroying the damper body in the vise. Also you need that if you need to change the damper shaft.
