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

M4WD-33/LB double aluminium rollers for 8-9mm mount centres

These double aluminium rollers are an aftermarket set designed for Mini 4WD use. Each piece is machined from aluminium and finished in anodised light blue. The description focuses on fitment, spacer considerations, and practical handling notes that experienced hobbyists rely on when selecting roller hardware for chassis types like Super-II, MA and MS.

They mount using standard 8-9mm spacing; check shaft clearance and spacer stacks with your chosen damper or stay configuration. The anodised surface shows less visible wear than bare metal, and good machining tolerance usually results in repeatable concentricity once installed correctly. The colour is handy for themed builds and display models.

This supply-level hardware is not a chassis-specific performance mod. Confirm thread sizes and spacer combinations before final assembly, and do not use these rollers on Wild Mini 4WD or Scale Mini 4WD lines where metal rollers are outside intended use.
