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

Front bumper upper plate in graphite for TRF421

The Factory Pro FP-O-TCP008 is an RC-scale bumper upper plate made specifically for the Tamiya TRF421 chassis. Constructed from graphite, it serves as a direct replacement to support chassis setup and tuning work.

This plate is intended purely for RC setup: it mounts to the TRF421 bumper area and alters local stiffness and how loads transfer through the front end. Swapping to the graphite plate lets tuners explore changes in chassis rigidity and measure the resulting effects on shock behaviour and steering feel without touching suspension geometry pieces.

Fitment is straightforward for competent model technicians: remove the original bumper upper plate from the TRF421, fit the Factory Pro graphite plate into the same points, and check fastener engagement and clearance. After installation, revisit ride height and shock alignment and perform brief running to confirm the change before final adjustments.

The description applies only to an RC hop-up for the Tamiya TRF421 and does not apply to full-size vehicles.
