TAMIYA GP401 Heavy Mass Damper Set for Mini 4WD – Grade Up Parts

Overview

Introducing the GP401 Heavy Mass Damper Set from Tamiya, a Grade Up Part crafted to fine-tune the weight balance of Mini 4WD racers. This heavy damper adds concentrated mass to the damper assembly, enabling more controlled responses on varied terrains and during dynamic maneuvers.

Why pick the GP401 Heavy

The lightweight chassis still benefits from targeted mass where it matters most. By adding heft to the damper system, you can influence how the car settles after a jump, how it reacts on downhill runs, and how it handles quick direction changes on the straightaways.

• Improved balance on slopes, helping maintain grip during uphill and downhill runs.
• Seamless integration with Tamiya Grade Up Parts and the GP401 line for upgrade compatibility.
