The Factory Pro O-TCPF05 is an RC-scale centre damper stay produced for compatibility with the Tamiya TRF104 chassis. Machined in graphite 2.5 as described in the product name, it serves as the structural interface and mounting point for the centre shock setup on suitable TRF104 cars.
Functionally the stay determines damper angle and how forces are channelled through the chassis centre. Replacing the stay alters the relationship between damper and chassis flex, providing a discreet way to tweak mid-corner balance and transient response without changing the damper cartridges.
Fitting advice: follow your chassis manual to remove the stock stay, set the Factory Pro piece into the existing mounts and secure with original screws. After installation check stroke clearance and mounting symmetry. Standard hex keys are all that is normally needed, and a static setup check is recommended before running.
This component is supplied as an aftermarket spare for hobby tuning and maintenance, and it is specified for TRF104 compatibility as shown in the listing.
