Air Fill Adaptor | STL File (No physical product)
The Air Fill Adaptor is the digital version print file of the new adapter FOX uses on the DHX2 and Float X2. It is functionally equivalent to the 2026 FOX Float X2 & DHX2 Air Fill Adaptor (#803-04-357) and is also compatible with any shock that uses the standard red RockShox air fill adapter. Our version is the same design but longer.
If you have access to a 3D printer, you can print this adaptor and use it for your suspension service without needing the OEM tool.
You will need to buy a -006 N70 o-ring.
⚠️ Fair warning: this is a DIY printed tool. It will do the job, but at some point it will probably break off inside your shock. The threads on the shock side are very small, do not overtighten, be gentle. The o-ring does the sealing, not the torque. Check the photos, I show exactly how to use the knife technique to extract it when it breaks. If you're a pro or doing this regularly, the real OEM tool is worth buying. This one is for the home mechanic who needs to get the job done.
This is a digital STL product only. You print it yourself.
How It Works
The adaptor threads into your shock's air valve port and allows you to fill or bleed the air chamber during service. It works the same way as the OEM FOX and RockShox equivalents, just with a longer body because the rezi blocks the old one by 1-2mm.
The threads on the shock are very small and delicate, finger tight is enough. The -006 N-70 o-ring is what creates the seal, so do not rely on torque. Over-tightening is the fastest way to break the adaptor off inside your shock.
If it does break off, don't panic, check the photos for the knife technique. Insert a thin blade into the adaptor and carefully unscrew it out of the shock.
Important Notes
This tool is only intended for shocks compatible with the standard red RockShox air fill adapter or the FOX Float X2 & DHX2 air fill adaptor.
Always have your -006 N-70 o-rings ready before use. Without them, you will not get a proper seal.
Do not overtighten. The threads on the shock side are small and the tool is 3D printed. Finger tight is all you need, the o-ring handles the seal.
If the adaptor breaks off inside the shock, do not panic. Check the photos, insert a thin knife blade into the adaptor body to carefully unscrew and extract it. Take your time and work gently.
