This two-piece set of machined aluminium rocker arms replaces the stock TC-01 plastic components and is intended for RC-scale use where consistent linkage behaviour and reduced wear are priorities. The arms are machined to align with the TAMIYA TC-01 geometry and come finished in red anodising.
Fitting is a direct replacement procedure: remove the original rocker assembly, transfer bearings or pins if appropriate, install the aluminium arms and reassemble while confirming full articulation and clearance. Maintain the original hardware orientation to preserve intended suspension geometry.
In tuning contexts the aluminium rocker arms provide a stable pivot that limits flex, helping you refine roll centre and leverage adjustments in a controlled, repeatable manner rather than masking changes with plastic compliance.
