Upgrade your Mini 4WD with Tamiya 94758 JR 19mm rollers

The Tamiya 94758 JR 19mm Aluminum Ball Race Roller is a practical upgrade for Mini 4WD hobbyists who want better track manners. Machined aluminium construction gives long-term durability and consistent rolling under race conditions. The gun metal finish helps lower surface friction, which supports smoother cornering and improved stability on technical layouts.

Features, bearings and fitment

This roller set fits both standard Mini 4WD and Mini 4WD PRO chassis, making it a flexible choice for different builds. The included 520 ball bearings reduce rotational drag for a cleaner roll, and the package contains screws, rubber rings, and aluminium spacers so you have what you need to install them on most setups.

How do I install these rollers on my Mini 4WD?

Use the supplied screws and spacers to mount the rollers to compatible roller stays. Check alignment and clearance so the roller spins freely without rubbing the body or guide rails.

Will the gun metal finish affect durability?

The gun metal coating is primarily cosmetic and helps resist surface wear; the aluminium core provides the main strength for racing use.

Are the 520 bearings replaceable?

Yes, the 520 ball bearings can be replaced with the same size bearing if you want to service or upgrade the rollers over time.
