Tamiya Mini 4WD Double Roller Set 12-13mm M4WD-34/LB by 3Racing  [M4WD-34/LB]

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

Crafted for hobbyists who maintain 1/32 Mini 4WD machines, these double rollers are CNC-machined from aluminium and anodized light blue. The pair is made to accept 12-13mm outer diameters and suits compact roller mount configurations.

They are compatible with standard Tamiya Mini 4WD mounting points that accept 12-13mm double rollers. This product is a replacement roller assembly rather than a chassis or motor part, so check shaft diameter, spacer thickness and bearing type to confirm fit on Super-II, MA, MS and similar performance chassis.

Fitting advice: inspect for bearing play and ensure shafts run true, use thread-lock or locking hardware on metal joints that might loosen, and verify roller clearance with bumpers and stabilisers. The anodised coating is mainly cosmetic; avoid overtightening to prevent deformation or thread damage.

Care advice: remove grit after running on abrasive tracks, re-lubricate bearings periodically, and swap rollers in matched pairs to keep handling predictable. These rollers focus on consistent roll and longevity rather than shaving grams.
