Introducing the Tamiya 94739 JR 19mm Blue Roller

The Tamiya 94739 JR 19mm Aluminum Ball Race Roller is a limited edition performance part that improves the behaviour of Mini 4WD cars. Made from lightweight aluminum with a blue anodized finish, these rollers house 520 ball bearings to promote smooth rotation and reduce unwanted resistance on straights and bends.

Suitability and What You Get

These rollers are compatible with both Mini 4WD and Mini 4WD PRO chassis, offering an easy way to refine handling. The kit contains screws, 520 ball bearings, rubber rings and aluminum spacers so you can fit them without sourcing extra parts. They make a practical upgrade for competitive racers and hobbyists who care about both function and appearance.

Will these rollers help lap consistency?

By reducing friction and delivering steadier rotation, the 520 bearings can contribute to more consistent lap times, particularly on technical tracks.

Are spare parts available for this set?

The pack includes essential spares like rubber rings and spacers; additional bearings and screws can be purchased separately if needed.

Can I mix these with different roller sizes?

You can combine these 19mm rollers with other size setups for specific handling goals, but ensure correct mounting and clearances to avoid contact with the track.
