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

Light blue 12-13mm double rollers M4WD-34/LB for Mini 4WD

These double aluminum rollers are intended for experienced Mini 4WD builders who need a durable spare for 1/32 scale 4WD models. Machined from aluminum and finished in light blue anodizing, the pair accepts 12-13mm outer roller diameters and is made for compact roller mount layouts.

Compatibility is with standard Tamiya Mini 4WD mounting locations that accept 12-13mm double rollers. This listing is for replacement roller assemblies only, not for a chassis or motor; confirm shaft diameter, spacer stack and bearing type before fitting to Super-II, MA, MS or other tuned chassis.

Installation notes for experienced users: verify bearing clearance and shaft alignment, use appropriate thread locker or lock-nuts on metal-fastened joints, and check roller height against stabiliser or bumper clearances. The anodized finish is cosmetic; avoid overtightening fasteners which can deform rollers or strip threads.

Maintenance tips: clean and lightly re-lubricate bearings on a regular schedule, inspect rollers for burrs after abrasive track use, and replace rollers as a matched pair to preserve handling balance. These rollers prioritise durability and consistent rolling over weight savings.
