3Racing M4WD-33/PK Double aluminum rollers 8-9mm for Tamiya Mini 4WD 4WD chassis spare roller accessory  [M4WD-33/PK]

3Racing M4WD-33/PK double aluminum rollers for Mini 4WD setups

These double aluminum rollers from 3Racing come in an 8-9mm size and a pink anodized finish. The component is a pair of matched rollers made from machined aluminum intended as a replacement or visual upgrade for Mini 4WD that accept 8-9mm roller fittings.

The double-roller format keeps the roller assembly compact while providing two contact surfaces on each side. The aluminum construction and anodized coating focus on dimensional stability and surface durability rather than rubber traction. Fitment depends on the roller post and spacer arrangement of the host chassis; verify axle and post clearances before installation.

For experienced builders: these rollers are best considered a hardware-level spare or styling part. They do not include bearings or mounting hardware unless listed by the vendor. Avoid using this item on non-compatible series that require specific roller profiles; confirm compatibility with the target MA, MS, AR, FM-A, VS, Super-II or other performance-oriented chassis if applicable.
