Tamiya 15390 Fluorine Coated Straight Gear Shaft Set (2pcs) - Mini 4WD Drivetrain Polish  [15390]

Tamiya 15390 - Fluorine finish straight gear shafts (2pc set)

The Tamiya 15390 shafts are treated with a fluorine coating to encourage smoother rotation in Mini 4WD drivetrains. The surface treatment helps lower friction and can reduce dependency on external lubricants during regular running.

Compatibility across Mini 4WD chassis

These shafts fit many Tamiya Mini 4WD frames, including Mini 4WD Pro, MS, Super TZ-X, Super TZ, Super FM, FM, Super 1, Zero, Type 5, Type 4, and Type 2. Their wide fitment makes them a versatile replacement or upgrade part.

Trackside effects and practical gains

With reduced surface friction from the fluorine layer, gear movement becomes more consistent and less prone to drag. That smoother rotation supports stable lap times and fewer on-the-spot adjustments during events.
