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

Solid aluminum rear lower arm for DT-03

This machined aluminum rear lower suspension arm is made specifically for the Tamiya DT-03 chassis as a direct-replacement hop-up part. The aluminum construction gives a stable mounting surface and reduces inconsistent flex compared with the stock plastic arm, which helps when you adjust rear roll stiffness or fine-tune camber and toe settings.

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

For practical tuning the arm acts as a rigid link in the rear suspension, holding geometry under load and enabling repeatable adjustments when you change shock valving or rear toe blocks.

Choose 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.
