Tamiya 15523 Racing Low Friction Bearing Set for Mini 4WD  [15523]

Smooth rolling upgrade for mini 4WD setups

The Tamiya 15523 Low Friction Plastic Bearing Set is built to reduce drivetrain drag and boost the efficiency of your Mini 4WD car. The kit contains several bearing types intended to fit common shaft and gear positions on racing models.

Bearing types and fitment

• Low-Friction 620 Plastic Bearings: Suited for hex shaft axles, these bearings cut rotational resistance and help maintain speed through straights.
• Low-Friction 520 Plastic Bearings: Made for counter gears in Mini 4WD PRO setups, these bearings help the drivetrain run with less energy loss.
• Compatibility: Works with both Mini 4WD and Mini 4WD PRO cars, making it a versatile upgrade across popular chassis.

On-track benefits and setup tips

Fitting low-friction bearings reduces mechanical drag so wheels and gears spin more freely, which can improve lap consistency. They are a straightforward modification for racers and hobbyists wanting cleaner drivetrain behavior without changing core components.
