This is an aluminum rear upper suspension link arm designed for TAMIYA CC-02 chassis fitment, manufactured and sold under the JAZRIDER JR-CC208-LB designation.
As a direct-replacement hop-up for the rear upper link location, the alloy arm provides a stiffer mounting point compared with common plastic pieces, helping to reduce flex at the upper link pivot during cornering and load transitions. It interfaces with the existing CC-02 chassis mounting points and standard link ball/posts without requiring chassis modification.
Installation is straightforward: remove the stock rear upper link, transfer any existing hardware and pivot balls, and fit the aluminum arm using the same attachment points. After installation, check alignment and suspension travel through the full stroke to confirm there is no binding and to set desired roll center and toe influences during tuning.
In tuning use, aluminum rear upper links are typically paired with matching uprights and lower links to maintain predictable suspension geometry. Use this part when you need crisper rear response and more consistent toe change under load, especially on rough or high-speed sections where plastic links may deflect.
