Tamiya 94934 JR 17mm Roller Pack for Mini 4WD

The Tamiya 94934 JR 17mm Aluminium Rollers feature a durable aluminium hub and low-friction plastic rings to help control lateral forces through bends. Ball bearings are fitted at manufacture to ensure even spin and reliable rotation under load.

These rollers fit both Mini 4WD and Mini 4WD PRO machines, making them a versatile upgrade for hobbyists refining handling or preparing for competitive runs. They are well suited to setups where consistent roll behaviour matters.

Will they affect front end grip?

Roller material and size can change how the car tracks through corners. These low-friction rings aim to reduce drag rather than increase grip, so balance front and rear settings accordingly.

How often should bearings be checked?

Inspect bearings after heavy use or every few track sessions. Clean and relube as needed to prevent grit from reducing spin efficiency.

Are these allowed in organised club races?

Rules vary by club and event. Check class regulations before racing, but these rollers are commonly accepted in modified Mini 4WD categories where aluminium parts are permitted.

What simple tweaks improve performance with these rollers?

Fine-tune roller offset, adjust toe-in/out, and pair the rollers with suitable tyres. Small alignment changes often yield noticeable improvement in corner exits.
