Tamiya 15344 JR DR 9mm Ball Bearings overview

These Tamiya 15344 JR DR 9mm Ball Bearings are built for Mini 4WD racers who want a straightforward performance upgrade. They are compact bearings made to fit common Mini 4WD wheel assemblies and help the car run with less drag.

Performance role and fit

The 9mm bearings cut down on friction inside wheel hubs, enabling smoother wheel spin and more efficient power transfer. Their dimensions suit a broad range of Mini 4WD chassis, making them useful for many setups from stock to tuned machines.

Installing these bearings can improve consistency through straights and corners by stabilizing wheel rotation. While not a guarantee of faster times on every track, they make tuning and fine adjustments more effective for competitive runs.
