The Factory Pro FP-O-TCP003 split upper deck is tailored for the Tamiya TRF421. Built from 2mm soft graphite, it introduces tuned flexibility to the chassis so you can hone handling characteristics for tight or flowing layouts. It is a practical upgrade for racers who want a more adaptable TRF421 setup.
The soft graphite composition of the FP-O-TCP003 helps the chassis absorb small impacts and chatter, improving tyre contact and overall stability. This can translate to cleaner exits and more predictable responses when pushing the limit.
The deck matches the TRF421 chassis geometry and installs using the original mounting points. Installation is straightforward, making it easy to test different deck flex options between practice runs.
For Tamiya TRF421 owners aiming for a balanced handling feel, the Factory Pro FP-O-TCP003 delivers a useful blend of durability and give. The 2mm soft graphite is ideal for fine tuning rather than radical chassis changes.
