Tamiya 15401 Heavy Mass Damper Set - Mini 4WD Upgrade  [15401]

Introduction to the Tamiya 15401 Heavy Mass Damper

The Tamiya 15401 Mass Damper Set (Heavy) is an upgrade aimed at improving track stability for Mini 4WD cars. Its heavier damping helps reduce unwanted motion so drivers can hold cleaner lines through complex sections.

What It Does and Where It Fits

The mass damper soaks up vibration and limits bounce, which is especially useful on banked corners and raised track features. It can be mounted front or rear on many Mini 4WD PRO and standard chassis to tailor handling balance.

Benefits During Competition

By limiting excessive movement, the Tamiya 15401 helps maintain cornering precision and steadier exit speeds on technical tracks. The added weight contributes to better traction and lowers the chance of the car becoming unsettled under load.
