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

Factory Pro TRF421 main chassis

This Factory Pro main chassis is a direct replacement-style graphite plate intended for use on the Tamiya TRF421 1/10 on-road racing chassis. As a chassis component it concentrates on baseline rigidity and flex characteristics that influence balance and traction rather than adding features or hardware.

Use this chassis plate when you need a like-for-like graphite option to adjust the car's overall stiffness. Because it is a core structural part, fitment should be checked against existing mounting points and peripheral parts such as servo mounts, motor position, and suspension geometry before final assembly.

For tuners this chassis is a straightforward component to manage chassis stiffness and weight distribution; confirm alignment with existing TRF421 parts and test setup changes gradually to evaluate handling differences.
