This is an aluminum front lower suspension arm in light blue designed for the Tamiya TT-02 scale RC chassis. The item is intended as a direct replacement for the TT-02 front lower arm and is provided as an aftermarket RC accessory only.
The alloy arm reduces flex compared with many stock plastic arms, helping to stabilise the front suspension pick-up and support more consistent steering response during driving. The part is finished in light blue aluminium as indicated in the product name.
Installation notes: fit the arm to the TT-02 front lower suspension mounting points using the chassis' existing attachment locations. Verify fitment with your TT-02 variant before completing assembly and ensure your fasteners and ball studs are the correct specification for the replacement arm.
For tuning: incorporate this arm into step-by-step front-end adjustments such as roll centre, caster and anti-squat changes; modify one parameter at a time and test on a suitable surface to judge handling differences.
