Description
Ten spare G-22 gears in pink for Mini 4WD PRO cars. They replace the G-22 gear used in the PRO drivetrain, or the equivalent gear supplied in Item 15349, so this is a maintenance pack for racers working through gears from wear or breakage rather than a single spare part.
Mini 4WD PRO cars run their own chassis and gearbox layout, separate from the classic Type/Super series, so PRO-specific gears like the G-22 aren't interchangeable with gears meant for those other cars — this pack exists because the PRO drivetrain uses its own gear rather than sharing one across the wider catalogue. Pink is Tamiya's colour code for this particular gear within the PRO parts range, letting it be picked out at a glance from a mixed parts box without checking the tooth count. Ten pieces is enough to keep a PRO car running through repeated wear over several seasons without needing a full replacement gear set each time.
- Gear: G-22
- Colour: pink
- Quantity: 10 pieces
- Compatibility: Mini 4WD PRO chassis; also replaces gears in Item 15349
