Tamiya 10312 AO-1041 G-18 Yellow Gear Set (10pcs) - Mini 4WD Spare  [10312]

Quick look at the Tamiya 10312 AO-1041 G-18 yellow gear set

This 10-piece yellow gear set from Tamiya is built as a no-nonsense replacement option for Mini 4WD racers. Keep a set in your toolbox to swap in fresh gears when wear starts to affect lap times.

Where these gears fit

The G-18 gears suit several popular Tamiya chassis: Super X, Super XX, VS, Super TZ, Super TZX, AR and Super II. Their fit and tooth form make them a practical choice for mixed fleets and tuning sessions.

Performance notes

Paired with the GP.434 high-speed EX counter gear, the G-18 supports a 3.7:1 gear ratio that helps balance low-end punch with top speed. Low friction and accurate moulding help keep power delivery consistent under race conditions.

Practical upgrades

Use these gears to trial different ratios or replace fatigued parts after heavy running. They are a good baseline part for anyone building or maintaining a competitive Mini 4WD car.
