Tamiya 3RACING M4WD-32/RE 19mm Red Aluminium Ball Race Rollers (Ringless)  [M4WD-32/RE]

Quick Look at the 3RACING M4WD-32/RE Rollers

The Tamiya 19mm red aluminium ball race rollers, identified as 3RACING M4WD-32/RE, provide a lightweight stability upgrade for Mini 4WD cars. Built without rings, these rollers favour direct contact while keeping overall mass low for nimble track behaviour.

Fitment and Function

These 19mm rollers suit a variety of Mini 4WD chassis types including MS, MA and AR. They help reduce rolling resistance at the guide rails and improve cornering predictability, making them a go-to choice for racers on technical circuits.

Practical Gains on the Circuit

By tightening lateral control and keeping alignment steady, the rollers aid consistent lap times. The ringless face increases rail feedback, which is beneficial when driving through sharp chicanes or quick direction changes.
