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

Aftermarket front upper arm for TT-01d

This aluminium front upper arm is an aftermarket replacement for the TAMIYA TT-01d chassis, identified as model TT054D. It fits as a direct replacement for the original front upper arm and is intended for repair work or minor tuning without changing the chassis layout.

Built in aluminium alloy, the component increases stiffness compared with typical plastic arms. That added rigidity helps keep suspension geometry stable while producing a firmer front-end feel that can subtly affect steering precision and camber under cornering loads.

Fitting is straightforward: remove the original arm, transfer hinge pins and original hardware, fit the alloy arm in the same orientation, and verify there is free movement through the suspension travel. After installation, recheck wheel toe and camber to match your previous setup.

Use this part as a passive way to stiffen the front suspension; it is best paired with your existing spring and damper settings for consistent handling. The arm is supplied as an aftermarket component for model cars and hobby running.
