Tamiya DT-03 Rear Lower Arm (Aluminium) JR-DT301-OR Upgrade by Jazrider  [JR-DT301-OR]

Precision aluminium rear lower arm for DT-03

This aluminium rear lower suspension arm is manufactured to suit the Tamiya DT-03 chassis as a direct-replacement hop-up component. The machined aluminium face yields a more consistent mounting point and predictable flex compared with the original plastic arm, which benefits adjustments to rear roll, camber and toe angles.

Compatibility is specific to the DT-03 mounting layout; fitting follows the chassis' standard rear lower arm positions. The orange finish aids visual inspection and matches many upgrade component sets for easy identification.

During tuning work the component functions as a stable rear link, keeping geometry steady under load and supporting repeatable setup changes when you modify shock rates or toe settings.

Select this arm when a durable metal mounting point is needed for consistent DT-03 rear setup; confirm fit and keep original fasteners if serviceable.
