This rear upper suspension link is an aluminium upgrade part for the TAMIYA CC-02 chassis, designed to replace the OEM plastic link while keeping the original mounting positions unchanged.
The stiffer alloy link reduces flex at the upper pivot, giving a more consistent geometry through compression and rebound. That consistency makes tuning spring rates, shock positions, and anti-roll setups easier to evaluate.
Installation uses the stock link locations on the CC-02. If the mounting holes are aligned, reusing the factory screws and ball studs is acceptable; verify free movement across the suspension travel and correct any binding at extreme positions.
View this as a tuning aid rather than a performance upgrade that changes fundamentals. Use it alongside proper shock tuning and chassis trim to achieve balanced rear traction and cleaner turn-in response.
