Race Grade Support Plate for TRF421 Chassis

The Tamiya 9803475 Upper Deck B improves torsional rigidity on the TRF421 chassis, helping the car track truer through a sequence of corners. Machined and finished to tight tolerances, this plate helps keep setup changes predictable run after run.

Better Response Under Load

Reducing unwanted chassis flex gives more immediate steering feedback and steadier front traction under heavy cornering forces. That stability helps when you are dialing in sensitive steering settings.

Direct Fitment for TRF421 Builds

Made to match the TRF421 mounting points, this upper deck integrates cleanly into the stock layout and reinforces key structural areas for extended durability during club or track racing.

The Upper Deck B is produced from a high quality material chosen to balance stiffness and durability for racing conditions.
Any added mass is minimal compared to the handling gains; the part is engineered to increase rigidity without penalising balance excessively.
After fitting the Upper Deck B, check camber, toe and shock settings as the chassis behaviour will tighten and may require small adjustments for best lap times.
