The Tamiya 15259 DR Hex Hole Ball Bearing Set is a sensible upgrade for Mini 4WD hobbyists seeking reduced friction in their drivetrains. These bearings allow drive shafts to rotate more freely, aiding smoother motion and helping models maintain steady speeds during laps.
Made to integrate with typical Mini 4WD layouts, the bearings reduce drivetrain load and support a cleaner transfer of power from motor to wheels. They are useful for racers refining performance and for builders aiming for reliable, low-friction operation.
