How does the VSS for Fox 40 / Bomber 58 differ from a standard volume spacer token?

Standard volume tokens are static—they reduce air chamber volume by a fixed amount at all times. The VSS uses patent-pending virtual volume technology to react to shaft speed: during slow or technical riding it behaves like 1–2 tokens, but ramps to the equivalent of 5–6 tokens (Standard) or up to 8 tokens (DH version) only during fast, high-energy impacts. This means riders get progressive support without sacrificing small-bump sensitivity.

Which version of the VSS should I choose for my Fox 40—Standard or DH?

The Standard version suits most riders: it builds support equivalent to ~5–6 tokens on hard hits while feeling soft everywhere else. The DH version is designed for aggressive bike park riding, racing, or very high speeds, reaching up to ~8 tokens during extreme impacts—yet it still feels controlled and relatively soft during normal riding. Neither version is harsh; the ramp-up only activates under fast, high-energy shaft speeds.

What is included with the VSS for Fox 40 / Bomber 58 and what does setup require?

Each VSS ships with one Smart Air Token (Standard or DH, as selected), three nozzles—your recommended size plus one softer and one firmer option—and a nozzle wrench. Before ordering, riders complete the VSS Configuration Tool (takes roughly 30 seconds) which automatically determines the correct baseline nozzle size. No ongoing maintenance is required; the token is 100% plastic with no moving parts.

Does the VSS for Fox 40 / Bomber 58 ship to Canada, and what does it cost?

Yes. Shockwave Parts is a Canadian retailer and the VSS for Fox 40 / Bomber 58 is priced at CAD $79.49 and listed as in stock. Canadian customers purchase directly through shockwaveparts.com.

Is the VSS for Fox 40 / Bomber 58 compatible with single-crown forks or other fork models?

No. The VSS for Fox 40 / Bomber 58 is explicitly designed for dual-crown configurations only and is compatible solely with the Fox 40 and Marzocchi Bomber 58. It is not rated for single-crown forks or other fork models. Shockwave Parts offers separate VSS variants for other fork platforms; check the Adaptive Air Tokens (VSS) collection for the correct fitment for your fork.

Adaptive Air Token for Fox 40 / Marzocchi Bomber 58

Patent Pending Technology

Compatible with Fox 40 and Marzocchi Bomber 58. Dual-crown only.

Run lower pressure. Get insane support when it matters. Stay composed everywhere else.

The VSS is 100% polymer and uses virtual volume technology to dynamically change your fork’s effective air chamber volume based on impact intensity and duration. No moving parts.

More Grip Lower pressure, better traction

Extreme Adaptive Support 2 to 6 or up to 8 tokens (DH version) on demand

Zero Maintenance 100% plastic, no moving parts

VSS Configuration Tool (Required)

Get your exact nozzle size in 30 seconds. The system selects the correct baseline automatically.

Two additional nozzles are included for fine tuning.

Choose Your Setup

1. Support Level (Required)

Standard: Builds up to ~5–6 tokens on hard impacts. Best for most riders.
DH Version: Can reach up to ~8 tokens in rare extreme hits. Still feels like 1–2 tokens during normal riding.

2. Nozzle Size (Required)

Controls how fast pressure builds inside the VSS. Your ideal size is selected automatically using the configuration tool.

Important: The DH version is not harsh. It only ramps aggressively during very fast, high-energy impacts.

What's Included

1× VSS Smart Air Token for Fox 40 / Bomber 58 (Standard or DH version)
Your selected nozzle
+1 softer nozzle
-1 firmer nozzle
Nozzle wrench

Pro tip: Start with the recommended nozzle. Adjust only if needed.

How It Works

Virtual volume, not physical volume. The VSS reacts to shaft speed, not position.

Slow riding / setup sections: Feels like 1–2 tokens
Fast terrain: Builds strong mid-stroke support (3–6 tokens)
Extreme impacts: Standard version peaks around 6 tokens, DH version can reach ~8

You get maximum support when needed, without killing small bump sensitivity or making the fork harsh.

Common Questions

Q: Should I choose Standard or DH?
A: Standard fits most riders. DH is for aggressive riders, bike parks, racing, or very high speeds.

Q: Is the DH version harsh?
A: No. It only ramps harder during extreme hits. Most of the time it still feels very controlled and relatively soft.

Q: Do I need to change pressure?
A: Usually no. Some riders drop pressure slightly for more grip.

Q: Does it need maintenance?
A: : No. 100% plastic with no moving parts. Conservative lifespan is 2-3 years, but realistically it could last a lot longer.

Q: Is this just a bigger token?
A: No. It adapts dynamically. It’s soft when you need grip and ramps hard only when required.

About the nozzles: Slower airflow = more support. Faster airflow = softer feel. Fine-tune in minutes.
