Tamiya 94731 JR 19mm Aluminum Ball Race Rollers - Performance Upgrade

The Tamiya 94731 JR 19mm Aluminum Ball Race Rollers are a precision upgrade for Mini 4WD crews who want smoother cornering and steadier runs. Machined from durable aluminum with a black dish finish, these rollers cut friction and help keep your car planted through technical sections on the track. They suit both Mini 4WD and Mini 4WD PRO platforms for racers fine tuning their setups.

Each roller ships with pre-installed 520 ball bearings chosen for low friction to promote consistent rotation and speed stability. The package also contains the necessary screws, spacers and rubber O-rings so you have the hardware needed to install and start testing right away.

Will Tamiya 94731 fit stock Mini 4WD chassis?

Yes, the rollers are designed to work with standard Mini 4WD and Mini 4WD PRO chassis; check mounting points and clearances on modified bodies before final fitment.

What handling benefit do 520 ball bearings give?

520 ball bearings reduce rotational friction, which helps rollers spin more freely and contributes to smoother corner transitions and steadier top-end behaviour.

Does the kit include installation hardware?

Yes, the set includes screws, spacers and rubber O-rings so you can mount the rollers without sourcing extra parts.
