Tamiya Mini 4WD Low-Profile Cuboid Weight 9g - M4WD-39/LB by 3Racing  [M4WD-39/LB]

M4WD-39/LB cuboid mass block for Mini 4WD

This light blue, rectangular 9g cuboid is supplied by 3Racing as a simple mass block for Tamiya Mini 4WD models. It serves as a fixed ballast for hobbyists looking to fine-tune static mass distribution on compatible performance chassis. It is not an active damper, but a reliable way to add measurable weight where space permits.

Fitment depends on chassis layout and any custom brackets in use. Many modelers install small rectangular blocks where they do not obstruct rollers, gears, or body mounts. The block is compatible with standard Mini 4WD accessory holes and universal damper clamps that accept compact rectangular masses.

Collectors may value consistent finish and colour matching. The light blue surface works well on visible mounting spots and coordinates with many aftermarket schemes. Always check mounting clearance and fastener security prior to track use; treat this item as a balance tool rather than a rule-based performance mod.
