This machined aluminum rear upper adjustable suspension arm is made for the Tamiya TT-02 chassis and finished in red anodize to resist wear. It serves as a direct, stronger alternative to the original plastic upper arm.
Its primary role is to allow accurate rear camber adjustment and to stabilise rear tracking during setup. Replacing the stock arm with this aluminium piece reduces flex at the upper mount, which can improve handling consistency for on-road use.
Installation follows the standard TT-02 procedure: remove the stock rear upper arm, transfer any spacers or pins required, then secure the aluminium arm into the factory mounting points. This information is applicable to model RC vehicles only.
