Direct-Fit Lower Bulkhead for TRF421 from Tamiya

The Tamiya #9803481 Lower Bulkhead is a genuine replacement part for the TRF421 chassis that restores factory geometry and helps keep handling consistent. It is aimed at modellers who service their cars regularly.

Stable Chassis Support for Better Feedback

By supporting suspension mounting points, this lower bulkhead contributes to steady handling and improved driver feedback on technical track layouts. The design reduces unwanted movement under load.

Replacement Part for Maintenance and Tuning

Whether fitting a fresh replacement or using it as part of a setup change, the Tamiya #9803481 Lower Bulkhead is compatible with TRF421 layouts and supports common tuning adjustments.

No chassis modification is required when used as a like-for-like replacement on a TRF421; it fits the original mounting points.
Lifespan depends on driving style and track conditions, but replacing damaged or warped bulkheads promptly avoids handling irregularities.
You can paint the part, but avoid heavy coats that may affect tolerances; test fit after painting to confirm screw clearances remain correct.
