Mini 4WD Double Aluminium Rollers 12-13mm M4WD-34/LB by 3Racing  [M4WD-34/LB]

Precision 12-13mm double aluminium rollers M4WD-34/LB for Mini 4WD

Designed for experienced Mini 4WD enthusiasts, these double aluminium rollers are machined and anodised in light blue for a reliable spare on 1/32 4WD cars. The pair accepts 12-13mm outer roller diameters and suits tight roller mounting arrangements.

They are intended for use with standard Tamiya Mini 4WD mounting locations that take 12-13mm double rollers. This is a replacement roller assembly only, not a motor or chassis unit; confirm shaft bore, spacer choices and bearing type before fitting to Super-II, MA, MS or similar performance chassis.

Fitting guidance: check bearing end play and shaft straightness, secure metal fastenings with the correct locking method, and verify roller height against bumpers and stabilisers. The anodised finish is decorative and resists wear better than paint, but do not overtighten fixings.

Service advice: keep bearings clean and lightly lubricated, inspect for burrs after abrasive track use, and change rollers as a matched set to maintain handling symmetry. These rollers are built for consistent roll and durability rather than for cutting weight or adding aerodynamic gains.
