Tamiya 42350 TRF420 Aluminum Lower Deck - High Grip Chassis Upgrade  [42350]

Stiffen Your TRF420 with Precision Aluminum

The Tamiya 42350 Aluminum Lower Deck is a practical upgrade for hobbyists who want to dial in their TRF420 chassis on high-grip surfaces. Its 2mm thick aluminum plate and diagonal slits give a controlled mix of rigidity and flex for corner bite and mid-corner stability.

Track-Oriented Stability and Finish

Made to match the TRF420 layout, this lower deck improves handling on sticky circuits while the black anodized coating helps resist wear. For a complete stack, use it with the carbon fiber upper deck Item 42349 to fine-tune torsional response.
