SHS 12:1 Gear Set for Version 2 and 3 — the shortest ratio in the range, and the one that asks most of everything around it. A gearbox part, not a bolt-on gain.

A 12:1 ratio turns the motor's work into speed rather than torque, which is why it sits at the top end of the range for rate of fire.

It is also the least forgiving choice. A short ratio wants a strong motor, a healthy battery and a spring it can actually pull, and it punishes a gearbox that has been shimmed carelessly.

If you are not chasing a high rate of fire specifically, a longer ratio will give you an easier life and a longer-lived gearbox.

Good to know before you buy

Short ratios pull hard on the motor. Check the motor height and the battery before fitting one.

Frequently asked questions

Will this raise my rate of fire on its own?
It changes the ratio, but the result depends just as much on the motor, the battery and the spring. Treat it as one part of a setup rather than a bolt-on.

How short is 12:1 really?
It is the shortest ratio commonly sold, a long way from the 18:1 most guns leave the factory with. Expect it to change how the whole gearbox behaves.

Do I need to reshim after fitting?
Yes, always. Any gear change means shimming from scratch, and a 12:1 set is unforgiving of a rushed job.

⚠ Not a beginner's first upgrade: a short ratio loads the motor and the trigger contacts hard, and a poorly shimmed box will not survive it.
💡 Titan Forge Airsoft tip: Shim it properly and check the motor height twice. A short ratio shows up every mistake in the build. Browse gearbox parts.
