Tamiya 3404073 Carbon Fiber Upper Deck for TRF419XR - Precision Racing Upgrade  [3404073]

Improve TRF419XR Rigidity with a Carbon Upper Deck

The Tamiya 3404073 Carbon Fiber Upper Deck is specifically produced for the TRF419XR and uses carbon fiber reinforced plastic (CFRP) for a stiff yet lightweight component. Its 2.0mm profile reduces chassis flex and helps maintain consistent geometry under load.

How Carbon Fiber Affects Handling

Because carbon fiber is stiff relative to its mass, this deck helps tighten the chassis feel and improves turn-in accuracy. That makes setup changes more predictable when testing different spring and damper settings.

Practical Fitting Recommendations

Install the deck ensuring correct alignment and uniform screw torque to avoid point stresses. After the first session, recheck mounting points and make small trim adjustments to fine tune handling.

A straightforward upgrade for drivers seeking a firmer TRF419XR platform, supporting cleaner inputs and improved lap consistency.
