Medium split top plate for TRF421 chassis

This Factory Pro component is a split upper deck made specifically for the Tamiya TRF421 touring car chassis. It is an RC-scale replacement top plate in graphite at 2mm thickness, intended as a direct-fit option for setup adjustments.

The medium split pattern gives racers the chance to tune local stiffness and fore-aft mass distribution without replacing the lower chassis parts. Once installed it becomes part of the chassis stack and affects flex traits used when tuning grip and balance on track.

Fitting is aimed at kit-savvy builders: remove the stock upper deck, carry over any spacers or mounting pieces, and attach the split panels to the factory points. Make sure bulkheads align and apply even torque to fasteners to prevent preload problems.

Will this fit a TRF421 without modification?

Yes. The O-TCP004 is designed to replace the stock upper deck on the Tamiya TRF421 and uses the same factory mounting locations.

Is the thickness and material listed correctly?

The part is made from graphite and is 2mm thick, matching the description provided with the product.

What should I check after installation?

After fitting, confirm the panels sit square at the bulkheads, re-use any spacers, and tighten screws evenly. Use test runs to see how the deck changes handling and stiffness.
