Tamiya TRF421 Upper Deck Graphite 2mm Upgrade - Factory Pro O-TCP002  [FP-O-TCP002]

Option upper deck for TRF421

This option upper deck fits the Tamiya TRF421 racing chassis. It is a 2mm graphite plate designed to replace the standard upper deck and bolt into the TRF421 upper-deck locations.

As a tuning item, the graphite plate increases local stiffness relative to softer stock parts, helping to alter chassis flex and front/rear weight transfer in predictable ways for setup refinement.

The upper deck uses the TRF421 stock mounting geometry and aligns with existing mounting points and fasteners. During installation, confirm screw engagement and clearance around servo, battery, and suspension before finishing assembly.

Use this 2mm graphite upper deck as a tuning choice on TRF421 cars to alter chassis stiffness and handling balance without changing suspension mounting points.
