Strengthen Your TRF421 with the Upper Deck A

The Tamiya #3404157 Upper Deck A is an engineered upgrade for the TRF421 chassis that enhances structural integrity. With careful machining and fitment for the TRF421, it reduces unwanted movement in the chassis and helps deliver a crisper driver feel during aggressive laps.

Better Balance and Reduced Flex

This upper deck is matched to the TRF421 geometry to lower chassis flex and stabilise the platform. The result is more consistent handling and improved turn stability, which supports confident driving on a range of track surfaces.

Ideal for Tune-Oriented Drivers

Drivers refining their TRF421 for competitive or club racing will find the Upper Deck A beneficial for fine tuning weight distribution and improving traction consistency throughout a run.

Yes, it generally works with common aftermarket braces that follow TRF421 mounting conventions, though check clearances before final assembly.
The Upper Deck A is designed to add structural benefit without excessive mass, keeping weight impact minimal while improving rigidity.
Inspect mounting screws and contact points periodically and tighten as needed to retain the deck's performance over time.
Expect subtle shifts in handling that may require small setup tweaks, such as roll centre or shock settings, to optimise balance.
