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

DT-03 rear lower suspension arm — precision aluminum

Designed as a direct-replacement hop-up, this aluminum rear lower suspension arm fits the Tamiya DT-03 chassis and delivers a machined mounting face for predictable flex characteristics. Aluminum construction improves repeatability compared with the stock plastic arm during setup changes.

Because the part matches DT-03 mounting points, installation uses the chassis' standard rear lower arm positions. The orange finish gives a clear visual reference when checking setups between runs.

In tuning scenarios the arm acts as a stable link that maintains geometry under acceleration and corner loads, which helps when you alter shock settings or rear toe.

Install this arm to gain a consistent metal mounting point for DT-03 rear tuning; verify fit and torque values during final assembly.
