Bumper Support for TRF421X

This Tamiya 3404179 bumper support is an RC-scale replacement part intended for TRF421 series maintenance and tuning. It serves as a straightforward structural component that supports the front bumper area on TRF421-compatible chassis, helping retain alignment after impacts and during setup changes.

Designed as a hop-up replacement, the part is primarily used when refreshing worn components or when adjusting front-end geometry during track tuning. Its role is to provide consistent mount points for the bumper assembly so suspension and steering settings remain repeatable between runs.

Installation is direct on TRF421-configured layouts, replacing the stock bumper support without altering core suspension geometry. When performing installation, verify fastener torque and bumper alignment before test running, and re-check after the first session to confirm seating and clearances.
