8-9mm double aluminium rollers for Mini 4WD M4WD-33/LB compatible with Super-II MA MS by 3Racing  [M4WD-33/LB]

8-9mm double aluminium rollers M4WD-33/LB for Mini 4WD shafts

This aftermarket double aluminium roller set is made for Mini 4WD applications. The components are machined from aluminium and finished with an anodised light blue coat. The copy concentrates on compatibility, correct fit, and practical setup notes that experienced builders use when selecting rollers for common racing chassis such as Super-II, MA and MS.

They use standard 8-9mm mounting spacing; confirm shaft and spacer clearances against your damper or stay arrangement. The anodised layer helps mask surface wear compared with untreated metal, and consistent machining can yield repeatable concentricity when everything is installed squarely. For show builds the colour helps maintain a consistent theme.

This product is supply-level hardware rather than a bespoke chassis upgrade. Verify thread sizes and spacer combinations before final assembly and avoid deployment on Wild Mini 4WD or Scale Mini 4WD lines where metal rollers are not intended.
