Factory Pro FP-O-TCP005 Tamiya TRF421 2mm Rear Split Upper Deck Hard Graphite  [FP-O-TCP005]

Graphite Rear Upper Deck from Factory Pro for Tamiya TRF421

If you run a Tamiya TRF421 and want to tighten the rear end, the Factory Pro FP-O-TCP005 Split Upper Deck Hard (Rear) is a sensible choice. Fabricated from 2mm graphite, it increases structural stiffness to lower flex and improve stability at speed.

Handling Gains from Graphite Material

Graphite keeps the upgrade light while adding strength, which helps the car respond more predictably to steering inputs. That balance is useful for maintaining speed through bends and when accelerating out of turns.

Designed Fit and Quick Swap

Made specifically for the TRF421 chassis, this split upper deck swaps in with minimal fuss, making it accessible to hobbyists and racers alike. The part matches the chassis mounting points for a neat fit without major modification.
