Tamiya 15393 JR Steel Bearings 4pcs - Fluorine Coated Mini 4WD enhancement  [15393]

Product highlights

The Tamiya 15393 JR Steel Bearing set provides a practical upgrade for Mini 4WD fans focused on reliability and smoother axle spin. These 620-size bearings use a fluorine coating to lower friction and resist wear under racing loads.

Where they fit and why size matters

Engineered to the 620 bearing standard, these units slot into typical Mini 4WD wheel assemblies. They fit popular chassis forms including MS, MA and AR, so integration into existing models is generally straightforward.

Performance gains on the circuit

Switching from plastic or plain metal bushings to fluorine-coated steel bearings results in cleaner rotation and improved stability. This upgrade helps cars hold speed through straights and maintain composure in tight turns.
