Tamiya TRF421X Split Upper Deck Front - Graphite 1.6mm O-TCP011S by Factory Pro  [FP-O-TCP011S]

Front section split upper deck designed for TRF421X

This Factory Pro front split upper deck is a 1.6mm graphite replacement made for the Tamiya TRF421X chassis, built as an aftermarket hop-up to align with the stock mounting points. The component forms the front half of a split upper deck layout, allowing model builders to alter front deck material and thickness without changing the mid or rear sections.

On-track the 1.6mm graphite plate increases front-section stiffness and changes response compared with the factory plastic deck, delivering a predictable shift in front-end behavior. Fit the plate using the TRF421X's existing screw locations and hardware, and verify alignment and clearance around the servo, steering linkages and front suspension components before running.

Fitment is specific to the TRF421X platform; confirm your chassis uses a split upper deck configuration prior to replacing the stock front piece. As this is an RC-scale component, inspect mating surfaces for burrs and follow the chassis manufacturer's recommended fastener torque to avoid creating stress concentrations in the graphite.
