Quick look at the Tamiya 15449 roller upgrade

The Tamiya 15449 JR 17mm Aluminum Rollers with Plastic Rings provide a robust option for Mini 4WD hobbyists seeking cleaner cornering. The aluminium roller core is matched with a plastic outer ring to cut contact drag and keep runs predictable.

Features plus model compatibility

• Material: Aluminum roller cores with plastic outer rings
• Design: Three-spoke layout for reliable spin
• Compatibility: Suitable for Mini 4WD and Mini 4WD PRO models

How these rollers change handling

By lowering friction at the contact surface, these rollers help maintain speed through sequences of corners. The included ball bearings aid steady rotation, which is especially useful on technical or bumpy circuits.
