Quick look at the Tamiya Mini 4WD 17mm rollers

The Tamiya Mini 4WD 17mm Aluminum Ball Race Rollers (Ringless) in red are a practical upgrade for hobbyists aiming to refine their Mini 4WD handling. These rollers help improve stability in turns while keeping setup changes simple and predictable.

These aluminium ball race rollers deliver a low-friction rolling action that helps the car track cleaner through corners. The ringless configuration cuts drag and supports higher corner speed. They fit common Tamiya layouts like MS, MA, AR and VS, making them straightforward to add to most race cars.
