Track-Focused Rear Damper Stay for the TRF419X

The Tamiya 3404066 Rear Damper Stay is a purpose-built upgrade for the TRF419X chassis, produced from carbon fiber reinforced plastic (CFRP) with a 3.0mm thickness. Its stiff yet lightweight construction helps the rear of the car resist flex and maintain composure under high load.

Why Use Carbon on Rear Structural Parts

Carbon fiber brings a high stiffness-to-weight ratio that benefits parts affecting handling precision. As a rear damper stay, CFRP reduces chassis twist and gives drivers a firmer baseline for suspension and alignment adjustments on race day.

Compatibility and Installation Notes

Made to match the TRF419X mounting points, this damper stay installs cleanly with existing hardware. It is suitable for racers replacing worn components or choosing a stiffer option to tighten rear-end behaviour.

Can I use this on older TRF models?

This part is intended for the TRF419X layout; older TRF models may have different mounting patterns and could require different parts.

Does the CFRP stay affect weight distribution?

The stay is lightweight, so overall weight shift is minimal, but the increased stiffness changes rear behaviour, which can affect balance and tuning.

How should I check the fit after installing?

Verify that mounting screws are secure and that the shock and damper geometry is unchanged. Perform a gentle test run and adjust toe or shock settings if needed.

Is the finish prone to damage?

CFRP is durable but can be scratched or chipped on heavy impact; inspect edges and fastener holes regularly.
