TT-01d Front Upper Control Arm Aluminium Upgrade TT054D by GPM  [TT054D]

Replacement front upper control arm for TT-01d

This aluminium upper control arm is an aftermarket replacement intended for the TAMIYA TT-01d chassis, model TT054D. The component fits as a direct swap for the original part and is suitable for repairs or modest tuning without altering the chassis geometry.

Constructed from aluminium alloy, the arm improves structural rigidity compared with stock plastic arms. In practice this yields a firmer front-end feel while preserving the designed suspension geometry, which can subtly affect steering response and camber under load.

Fitment is straightforward: remove the factory arm, transfer the existing hinge pins and associated hardware, install the alloy arm in the same orientation, and check for unrestricted movement through the suspension cycle. After installation, inspect and adjust toe and camber to match your setup.

Use this arm as a stiffness upgrade rather than a way to change suspension geometry; combining it with your current shock and spring settings will keep handling predictable. It is supplied as an aftermarket part for model car hobby and track use.
