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

DT-03 Aluminium Front Upper Arm

This aluminium front upper arm is an aftermarket replacement produced by GPM for the TAMIYA DT-03 platform, supplied as 1 pr and intended as a direct replacement for the plastic original. It keeps the DT-03 mounting geometry while offering a stiffer material choice to reduce flex under load.

Fitment and installation are straightforward for anyone familiar with basic DT-03 maintenance: remove the factory front upper arm, transfer any reusable hardware and bearings, then secure the aluminium arm onto the existing mounting points. Standard tools such as hex drivers are sufficient for the swap.

In a tuning context this part is used to alter front-end response; replacing a plastic arm with aluminium changes stiffness and can affect steering feedback and weight transfer during cornering. Use this arm as part of measured changes when adjusting suspension and steering setups to understand its effect on handling.

Choose this aluminium front upper arm to replace DT-03 plastic arms when you need higher rigidity and consistent response for setup work; verify existing hardware and bearings during installation.
