Tamiya 3404179 TRF421 Bumper Support Replacement for TRF421X TRF421  [3404179]

Robust Bumper Support for TRF421X

This Tamiya 3404179 bumper support serves as an RC-scale replacement component for TRF421-series upkeep and setup. It acts as a reinforcing piece at the front bumper area on TRF421-compatible chassis to help retain alignment after knocks and during setup changes.

Built as a hop-up replacement, the part is used when replacing worn items or when fine-tuning front-end geometry for track conditions. Its role is to keep mounting points consistent so suspension and steering adjustments yield repeatable results.

Fitment is direct on TRF421-configured frames, swapping in for the stock bumper support without changing base suspension geometry. During installation, confirm fastener torque and bumper positioning, then re-check after the first run to ensure proper seating and clearances.
