The Tamiya 3404073 Carbon Fiber Upper Deck is made for the TRF419XR chassis and crafted from durable carbon fiber reinforced plastic (CFRP). The 2.0mm thickness gives added torsional rigidity to help the car stay planted during fast directional changes.
CFRP offers strong stiffness with minimal weight gain, making it a preferred choice for track tuning. Adding this deck reduces flex and helps the car respond more directly to steering and throttle inputs.
When fitting the Tamiya 3404073 deck, align it carefully and tighten screws in a cross pattern to prevent warping. After fitting, recheck your suspension and toe settings as the stiffer chassis can shift handling balance.
Built for track enthusiasts who demand a firmer platform, this upper deck tightens up TRF419XR handling for cleaner lap performance.
