Tamiya 3RACING M4WD-29/RE 9mm Red Race Rollers Ringless  [M4WD-29/RE]

Quick intro to Tamiya 3RACING M4WD-29/RE rollers

Tamiya's red 9mm aluminum ball race rollers are a ringless upgrade aimed at racers who want reduced drag and smoother rotation. The compact, lightweight design keeps your Mini 4WD nimble while supporting aggressive driving lines.

Friction reduction and fitment

The ball race mechanism minimises bearing drag and suits multiple Mini 4WD chassis standards. Because they are aluminium and ringless, these rollers add minimal unsprung weight and help preserve handling balance.

Race day improvements

These rollers lock in steady rotation to help maintain momentum through corners and reduce incidents of bounce on chicanes. Their durable build stands up to frequent club and event use.

Installation tips for reliable performance

Fit the rollers to the standard mounting points and check for smooth free spin after tightening. Avoid overtightening which can bind the bearing and degrade performance.
