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

Medium split upper plate designed for TRF421

This Factory Pro part is a split upper deck created for the Tamiya TRF421 touring car chassis. It serves as an RC-scale replacement top plate in graphite at 2mm thickness and fits as a direct replacement for the original deck.

The medium split layout permits builders to tune local stiffness and fore-aft mass distribution without modifying lower chassis elements. Installed into the chassis stack, the panels influence flex behaviour that is useful when adjusting grip and handling balance during setup.

Installation is aimed at experienced kit builders: remove the original upper deck, transfer any spacers or mounting hardware, and bolt the split panels to the factory mounting points. Ensure correct bulkhead alignment and apply even screw torque to prevent unwanted preload on the chassis assembly.
