3RACING M4WD-34/LB Aluminium Double Rollers for Tamiya Mini 4WD 12-13mm  [M4WD-34/LB]

Technical summary for the Tamiya Mini 4WD double aluminium rollers (12-13mm)

The 3RACING M4WD-34/LB double aluminium rollers in light blue are engineered to enhance lateral stability and refine cornering precision on Mini 4WD platforms. They provide a durable contact surface that reduces deflection under load, assisting consistent lap performance.

Compatibility and mechanical fit

These rollers are machined to suit common Tamiya Mini 4WD chassis types including MS, MA, AR and VS. The aluminium construction improves dimensional stability so roller alignment is retained under dynamic corner forces.

Performance and tuning notes

Compared with plastic rollers, aluminium reduces unwanted flex and contributes to smoother corner transitions. Use these rollers alongside fine tuning of gearing, tyre selection and mass distribution to optimise lap times on technical tracks.

Installation and servicing

Fitting is standard via the chassis roller mounts; check for correct spacer usage and secure fastenings to avoid axial play. Routine inspection and light lubrication of contact points will extend service life and maintain performance consistency.
