Tamiya DT-03 Aluminum Rear Lower Suspension Arm by JAZRIDER JR-DT301-OR  [JR-DT301-OR]

Aluminum rear lower arm for DT-03

This aluminum rear lower suspension arm is produced for the Tamiya DT-03 chassis and intended as a direct-replacement hop-up part. The machined aluminum construction gives a consistent mounting surface and predictable flex compared with the stock plastic arm, which helps when you are adjusting rear roll stiffness or fine-tuning camber and toe geometry.

Fitment is limited to DT-03 layout and mounting points, so installation follows the chassis' standard rear lower arm locations. The part is finished in orange to match upgraded component sets and to make setup checks easier during maintenance sessions.

In practical tuning work the arm functions as a stable link in the rear suspension, maintaining geometry under load and supporting repeatable adjustments when you change shock settings or rear toe blocks.

Use this arm when you need a repeatable metal mounting point for DT-03 rear setup work; keep original fasteners and check fit before final assembly.
