Tamiya DT-03 Aluminium Front Upper Arm Replacement - DT3054 by GPM  [DT3054]

DT-03 Front Upper Arm in Aluminium

This aluminium front upper arm is an aftermarket replacement designed for the Tamiya DT-03 chassis, supplied as a pair and intended to replace the original plastic arms. It preserves the DT-03 mounting geometry while offering higher rigidity to reduce deflection under load.

Fitting the arm is a routine task for those familiar with DT-03 maintenance: remove the stock upper arm, reuse any suitable bearings and fasteners, then mount the alloy arm to the existing points. A set of hex drivers and basic hand tools are usually all that is required.

When used for suspension tuning, replacing plastic arms with aluminium changes front stiffness and steering feedback, which can affect cornering balance. Incorporate this arm into controlled setup changes to evaluate handling differences.

Choose this aluminium upper arm for more consistent front-end behaviour on DT-03 vehicles; check and replace worn hardware or bearings during installation.
