Tamiya TRF421 Upper Deck 2mm Graphite Tuning Part - Factory Pro O-TCP002  [FP-O-TCP002]

Aftermarket upper deck for TRF421

This option upper deck fits the Tamiya TRF421 competition chassis. The item is a 2mm graphite plate intended to replace the standard upper deck and fasten to the TRF421 upper-deck mounting points.

As a tuning component, the graphite deck increases local stiffness in comparison to softer stock plates, allowing drivers to adjust chassis flex and front to rear balance with predictable results during setup changes.

The part uses the factory TRF421 mounting pattern and lines up with the stock holes and fasteners. When installing, confirm screw engagement and check clearances around your servo, battery and suspension parts prior to final assembly.

Use this 2mm graphite upper deck as a direct tuning option on TRF421 models to refine stiffness and handling balance while keeping original suspension geometry intact.
