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

Factory Pro TRF421 chassis plate for precision tuning

This Factory Pro main chassis is a replacement-style graphite plate designed for the Tamiya TRF421 1/10 on-road racing chassis. It concentrates on controlled stiffness and flex characteristics that affect balance and traction rather than incorporating extra features.

Install this plate when you want a comparable graphite option to change the car's stiffness profile. Because it is a primary structural part, verify fitment with existing mounting points and nearby components like servo position, motor placement, and suspension setup before completing assembly.

For competitive builders this chassis provides a simple way to adjust stiffness and weight bias; test changes gradually and confirm compatibility with other TRF421 parts.
