This is an RC-scale alloy upper arm manufactured for the Tamiya CC01 platform and provided as a single pair in the vendor listing. The link adopts a tie-rod arrangement with M3 threaded connection points and offers an aluminium-type alloy alternative to the original plastic arms for performance-minded hobbyists.
In service it functions as the upper suspension and steering link on the CC-01 chassis, locating the hub carrier and contributing to camber and steering geometry. It is recommended to perform a direct comparison with the factory arm to confirm hole spacing and mounting orientation prior to final assembly.
Installation notes: the arm uses M3-threaded tie-rod ends, so retain or source compatible M3 hardware and verify full thread engagement. Tighten fixings to a controlled, firm setting and validate full steering and suspension travel after installation to ensure there is no binding with the servo, linkage hardware, or wheel hubs.
