Tamiya TRF421 Graphite Main Chassis 2.25 for TRF421 - Factory Pro O-TCP001  [FP-O-TCP001]

Factory Pro TRF421 replacement chassis plate

This Factory Pro main chassis is a direct replacement-style graphite plate made for use with the Tamiya TRF421 1/10 on-road racing chassis. It focuses on baseline rigidity and controlled flex that influence balance and traction rather than adding extra features or hardware.

Choose this graphite plate when you need a like-for-like option to alter overall stiffness. As a core structural item, check alignment with existing mounting points and surrounding parts such as servo mounts, motor placement, and suspension geometry before final installation.

For tuners this chassis gives a straightforward way to manage stiffness and weight distribution; make setup changes incrementally and confirm alignment with other TRF421 components to assess handling effects.
