Super-II MA MS compatible double aluminum rollers 8-9mm M4WD-33/LB by 3Racing  [M4WD-33/LB]

Double aluminum rollers M4WD-33/LB for 8-9mm shaft spacing

These double aluminum rollers are an aftermarket roller set made for Mini 4WD racers and hobby builders. The parts are CNC-style machined from aluminum and finished in anodized light blue. The text emphasises fitment, clearance checks, and real-world handling notes that experienced builders use when choosing roller hardware for common racing chassis such as Super-II, MA and MS.

Installation uses standard 8-9mm spacing; verify shaft length and spacer stacks against your damper or stay layout. The anodized finish hides surface marks better than raw metal, and precise machining helps deliver consistent concentricity once fitted correctly. For display or themed builds the colour gives a neat, coordinated look.

This is supply-level roller hardware rather than a chassis-specific performance upgrade. Check thread sizes and spacer combinations before final assembly, and avoid using these metal rollers on Wild Mini 4WD or Scale Mini 4WD series where metal rollers are not intended.
