The Tamiya 15107 Hollow Propeller Shaft trims excess weight from the drivetrain, yielding faster spool up and an improved top end for Mini 4WD cars. Lightweight construction helps reduce stress on the motor while maintaining reliable drive transfer on race lines.
Installation is straightforward on compatible Tamiya Mini 4WD gearboxes, making this a practical upgrade for racers and weekend builders alike. Use it alongside balanced wheel and tyre choices to get the most from the reduced rotating mass.
