Tamiya DT-03 Aluminum Rear Lower Arm Upgrade - JR-DT301-OR by Jazrider  [JR-DT301-OR]

Rear lower arm in machined aluminum for DT-03

This machined aluminum rear lower suspension arm is produced for the Tamiya DT-03 chassis as a direct-replacement hop-up. The precise aluminium surface reduces variable flex versus the stock plastic part and gives a repeatable pivot point when tuning rear roll and toe characteristics.

Fitment is specific to DT-03 mounting locations, so install using the chassis' standard rear lower arm points. The orange finish helps visual setup checks and pairs with other upgraded components.

On the track the arm keeps rear geometry steady under load, helping to preserve handling changes you make to shocks and toe blocks across multiple runs.

Fit this arm when you want a consistent metal mounting point for DT-03 rear adjustments; confirm alignment before final tightening.
