Fit the Tamiya 3404156 lower deck to reduce unwanted chassis movement and achieve a more controllable TRF421 setup. The design focuses on delivering reliable stiffness that helps drivers fine tune handling characteristics.
A stiffer lower deck improves predictability through braking and cornering, making setup changes more repeatable. That consistency helps when dialing in suspension geometry and tyre choices.
Produced from robust materials, the Tamiya 3404156 is intended to resist the wear of regular track use. Its compatibility with the TRF421 chassis makes it a straightforward upgrade for those prioritising longevity and consistent performance.
