Factory Pro FP-O-TCP004 Tamiya TRF421 Split Upper Deck Race Tuned 2mm  [FP-O-TCP004]

Track-focused split upper deck for TRF421

The Factory Pro FP-O-TCP004 Split Upper Deck is a practical upgrade aimed at Tamiya TRF421 drivers who want firmer chassis control without extra weight. Fabricated from 2mm graphite, it adds purposeful stiffness where needed.

Predictable handling and roll control

The split configuration offers targeted flex so the car responds more predictably through corner entries and exits. That refined response helps when fine-tuning toe and roll centres for faster lap times.

Straightforward replacement and setup

Specifically produced for the TRF421, this deck installs with standard tools and is a quick swap. After fitting, brief on-track testing and small suspension tweaks will help you lock in the ideal setup.
