Tamiya 94787 JR 19mm Aluminum Roller Set - Compact Handling Upgrade

For those refining a Mini 4WD setup, the Tamiya 94787 JR 19mm Aluminum Roller Set delivers two red aluminium rollers plus plastic rings to tidy up cornering performance. The set is intended to stabilise the car while keeping installation simple for hobbyists and racers alike.

Fitment Notes and Usage

This roller set fits both Mini 4WD PRO and standard Mini 4WD chassis and includes spacers and screws for mounting. Correctly positioned rollers reduce side slip and help maintain cleaner racing lines through tighter sequences and sweeps.

Why Choose Aluminium Rollers

Aluminium offers a good trade off between strength and lightness, helping the Tamiya 94787 JR 19mm Aluminum Roller Set withstand repeated use while not unduly adding mass. The reduced friction and improved handling make it a practical upgrade for tuning lap times and keeping consistent performance.

Are these rollers suitable for beginner builds?

Yes. The Tamiya 94787 JR 19mm Aluminum Roller Set is straightforward to fit and can be a helpful upgrade for newcomers wanting improved stability without complex tuning.

Do the rollers require bearing upgrades?

The set is supplied with plastic rings and works well as is, though some racers may choose to fit low friction bearings or alternative bushings to further reduce resistance.

Can they be used with wider bodies or custom shells?

They can, provided there is enough clearance. Always check body and chassis clearance after fitting to avoid contact during cornering or chassis flex.

What track conditions benefit most from these rollers?

Tracks with frequent turns and technical sections will show the biggest gains in stability and line consistency from these rollers.

How should I store spare plastic rings?

Keep spares in a clean, dry box away from direct sunlight to prevent warping. Label parts so you can replace worn rings quickly between race sessions.
