TRF421X Split Graphite Rear Upper Deck, 2mm Upgrade for Tamiya - O-TCP012 by Factory Pro  [FP-O-TCP012]

Graphite split upper deck for TRF421X tuning

The Factory Pro O-TCP012 rear upper deck is an aftermarket, scale replacement crafted for the Tamiya TRF421X platform. Cut from graphite to a nominal 2mm thickness, the split configuration installs at the rear upper deck region to increase localized stiffness while maintaining necessary clearance for drivetrain and suspension articulation.

Choose this part when you want a controllable change in rear stiffness as part of your setup routine. Adding graphite to the upper deck alters how the chassis flexes and therefore affects traction and steering characteristics; balance these changes with adjustments to shocks, camber, and anti-roll elements.

Fitting is straightforward: remove the original rear upper deck component, locate the split graphite panel into position, and fasten using the chassis' existing screws. Take care not to over-torque the hardware to avoid damaging the graphite and confirm clearance before running.
