Tamiya DT-03 Precision Rear Lower Arm for Setup, Aluminum Red - JR-DT301-RD by Jazrider  [JR-DT301-RD]

DT-03 rear lower arm overview

This rear lower suspension arm is machined from aluminum as a direct replacement designed for the Tamiya DT-03 chassis, offering greater rigidity than the stock plastic component. It suits builders who want a repeatable mounting surface for demanding track use.

Fitting follows the usual procedure: remove the original arm, carry over any spacers or pins, and install the aluminum arm into the OEM mounting positions with the original hardware. Check hole alignment and clearances during a dry fit before torqueing fasteners.

As a primary suspension mounting surface, the rear lower arm helps preserve geometry during tuning, making it easier to assess changes to shocks, anti-squat and camber settings without component flex masking results.

Pick this aluminum arm when durability and consistent suspension geometry are priorities for maintenance and performance tuning.
