The Tamiya 3454921 Blue Upper Bulkhead is a precision aluminum upgrade tailored for the TRF418 chassis. It brings a crisp blue finish and reinforces the car's upper structure to cut unwanted flex and deliver more predictable responses through corners.
Made from lightweight aluminum, this upper bulkhead strengthens the TRF418 while keeping weight low. The exact machining helps preserve suspension geometry under load, which improves steering consistency and mid-corner stability for lap-to-lap repeatability.
For racers wanting tighter control, this blue bulkhead refines weight balance and front-end feedback, helping you extract more speed from smooth and bumpy surfaces alike.
