Tamiya TRF421 Graphite Bumper Upper Plate - Factory Pro O-TCP008  [FP-O-TCP008]

Graphite front bumper top plate for TRF421 tuning

This Factory Pro FP-O-TCP008 component is an RC-scale bumper upper plate produced for the Tamiya TRF421 chassis. The part is manufactured from graphite and is supplied as a direct-fit replacement to assist chassis tuning and setup tasks.

The plate is used solely within RC setup and adjustment: it secures to the bumper area of the TRF421 and modifies local stiffness and load transfer through the front end. Fitting this graphite plate allows drivers to compare chassis rigidity and observe effects on shock response and steering feedback without changing suspension geometry parts.

Installation is simple for experienced builders: remove the existing bumper upper plate from the TRF421 mounting points, fit the Factory Pro graphite plate to the same locations, and confirm screw engagement and clearance. After fitting, recheck ride height and shock alignment as part of the setup routine, then perform short test runs to validate changes before final tuning.
