2mm Pink Spacer Rings M4WD-01/PK

These 2mm pink spacer rings are a colour-coded accessory for making precise clearance adjustments on Tamiya Mini 4WD cars. They are intended to manage spacing around rollers and axle stacks and are not a replacement for drivetrain components. The pink finish helps when visually confirming stack height and lateral movement on finished builds.

Model builders fit 2mm spacers to refine roller stacks, reduce side play, or reconcile minor tolerances between third-party rollers and stock axles. The set acts as an affordable spare for service work, display preparation, or quick fixes.

The product description does not include material or tolerance specifications, so check axle and roller bore sizes prior to installation. Use the spacers for consistent fitment rather than treating them as a handling modification.
