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

DT-03 Aluminium Front Upper Arm Upgrade

This aluminium front upper arm is an aftermarket replacement for the Tamiya DT-03 platform, supplied as 1 pr and intended to directly replace the stock plastic component. It keeps the DT-03 mounting geometry while using a stiffer alloy to reduce flex under load.

Fitment is straightforward for anyone familiar with basic DT-03 maintenance: remove the factory front upper arm, transfer any reusable bearings and screws, then secure the alloy arm to the existing mounting points. Standard hex drivers and basic hand tools are sufficient for the swap.

In a tuning workflow the aluminium arm alters front-end stiffness and steering feedback, which can influence weight transfer in corners. Use this arm as part of stepwise suspension changes to assess its effect on handling and response.

Choose this aluminium front upper arm when you want firmer front response on DT-03 cars; inspect and reuse or replace existing hardware and bearings during installation.
