Top Plate Upgrade for the TRF419XR Chassis

The Tamiya 3404073 Carbon Fiber Upper Deck is tailored for the TRF419XR and manufactured from carbon fiber reinforced plastic (CFRP). Measuring 2.0mm thick, it boosts chassis rigidity to reduce flex and deliver cleaner steering input during competitive running.

Why Carbon Fiber Works Well

Because carbon fiber blends low weight with high stiffness, it gives more predictable handling without heavily loading the car. Installing this deck typically sharpens turn-in and improves mid-corner stability for quicker, repeatable laps.

Installation Notes and Care

Fit the deck with even screw torque and confirm alignment with the lower plate to avoid binding. Periodically inspect screw threads and mounting points to keep the setup consistent over multiple sessions.

Specifications

  • Material: Carbon Fiber Reinforced Plastic (CFRP)
  • Thickness: 2.0mm
  • Compatibility: Tamiya TRF419XR Chassis

A practical upgrade for drivers trimming their TRF419XR for club and regional events, offering improved rigidity and control.

Yes, it is designed to match the TRF419XR mounting pattern and should fit directly without trimming when used with the correct hardware.
The deck itself is thin, so it does not change ride height, but the added stiffness can alter handling feel which may require suspension tweaks.
Keep the surface clean, avoid overtightening fasteners, and inspect for delamination after heavy impacts. Small chips are common but monitor for structural damage.
