TAMIYA DT-03 Aluminum Rear Lower Suspension Arm by JAZRIDER JR-DT301-GU  [JR-DT301-GU]

Rear Lower Suspension Arm for DT-03

This is an RC-scale rear lower suspension arm designed for the TAMIYA DT-03 chassis, supplied as a metal replacement part intended for routine repair and setup adjustments. The part is offered in a gun metal aluminum finish and is presented as a drop-in option for builders who prefer metal components over stock plastic arms.

Compatibility is limited to DT-03-compatible layouts and mounting points. The arm is intended to occupy the same mounting locations as the original rear lower arm on DT-03 models, retaining alignment geometry while changing material properties for durability and tuning feel.

Use this arm as a tuning component to alter long-term wear characteristics and to provide a firmer mounting point for suspension pivots. It is described as suitable for maintenance replacement and incremental suspension setup changes within scale RC running and track preparation contexts.

Choose this arm when replacing worn rear lower arms on DT-03 cars or when switching to metal parts for a different suspension response during setup and testing.
