Improve lap consistency with Tamiya 94758 JR 19mm rollers

The Tamiya 94758 JR 19mm Aluminum Ball Race Roller is a solid upgrade for Mini 4WD racers focused on consistency. Built from aluminium for reliable wear resistance, the rollers keep their shape under repeated use. The gun metal finish helps cut friction at contact points, which supports neater cornering and steadier handling on varied tracks.

What is included and where it fits

This roller kit works with both Mini 4WD and Mini 4WD PRO cars, making it a handy part for many builds. Equipped with 520 ball bearings to lower drag, the set also includes screws, rubber rings and aluminium spacers for a complete install.

Will these rollers help on technical circuits?

Yes, reduced friction and stable roll can improve line holding on technical sections, as long as you match the roller height and tyre setup to the track.

Are the supplied spacers aluminium as well?

The kit includes aluminium spacers that work with the rollers to set correct clearance and maintain reliable rotation under load.

Do I need special tools to fit them?

Basic hobby tools such as a small screwdriver and pliers are enough; ensure screws are snug but not over tightened to avoid binding the bearings.
