Split upper deck option for TRF421

The Factory Pro O-TCP003 split upper deck is designed to suit the Tamiya TRF421 chassis. It uses a 2mm graphite plate with a softer layup to influence chassis flex and mid-corner behaviour while leaving the main chassis architecture untouched.

As a tuning accessory, the split upper deck changes how the chassis front and rear interact under cornering loads. Drivers employ it to tune understeer and oversteer balance and to control transient reaction when flicking between corners. The softer graphite offers measured compliance that helps grip without compromising mounting geometry.

Fitting the deck is straightforward for those familiar with touring car maintenance: remove the factory upper deck, transfer any necessary fixings, and secure the split deck to the existing screw points. Always check servo, motor and suspension clearances and alignment before final tightening to avoid rubbing or binding.

Compatibility

  • Tamiya TRF421
Yes. The softer graphite increases controlled flex which can improve mid-corner grip and make both entry and exit feel smoother, reducing abrupt handling shifts.
Typically it fits directly to stock fixing points, but you should confirm hole alignment and ensure no nearby components need adjusting during the trial fit.
Re-check roll centre, shock lengths and toe as a priority; small spring or damper changes may be required to return the car to your preferred balance.
