Factory Pro FP-O-TCP004 Tamiya TRF421 Split Upper Deck Medium 2mm Graphite  [FP-O-TCP004]

Refined chassis part for the TRF421

The Factory Pro FP-O-TCP004 Split Upper Deck gives Tamiya TRF421 pilots a practical route to tighter handling and clearer chassis feedback. Constructed from 2mm graphite, it keeps weight down while adding useful rigidity.

Better on-track balance and feeling

The split design separates the upper deck into sections so each side can react slightly differently, helping you tune roll characteristics and grip distribution for improved cornering consistency.

Designed for straightforward fitment

Made to match the Tamiya TRF421 layout, the part installs with common hand tools and minimal effort. Expect to make modest suspension adjustments to match your preferred driving style.
