3Racing M4WD-34/LB 1/32 4WD aluminum double rollers (12-13mm) light blue roller set for Mini 4WD  [M4WD-34/LB]

3Racing M4WD-34/LB double aluminum rollers for Mini 4WD

These double aluminum rollers are a spare part aimed at experienced Mini 4WD hobbyists who manage maintenance and visual consistency on 1/32 4WD models. Machined from aluminum and finished in light blue anodizing, the pair is sized to accept 12-13mm outer roller diameters and intended for applications where a compact, durable roller assembly is required.

Compatibility is with standard Tamiya Mini 4WD mounting locations that accept 12-13mm double rollers. The item is a replacement roller assembly rather than a chassis or motor component; users should verify shaft diameter, spacer thickness, and bearing type before installation to ensure fit with their Super-II, MA, MS or other performance-oriented chassis.

Installation notes for experienced builders: check for bearing play and preferrable shaft alignment, use appropriate thread-lock or lock-nuts where metal-to-metal contact may loosen, and confirm that roller height does not conflict with stabilizer or bumper clearances. The light blue anodized finish is primarily cosmetic; avoid overtightening fasteners that could deform the roller or strip threads.

Maintenance tips: clean and re-lubricate bearings periodically, inspect for burrs after use on abrasive track surfaces, and replace rollers as a matched set to preserve handling symmetry. The construction emphasizes durability and consistent rolling, not reduced weight or aerodynamic advantage.
