Tamiya DT-03 Aluminum Rear Lower Suspension Arm (Red) by JAZRIDER JR-DT301-RD  [JR-DT301-RD]

Rear lower suspension arm — DT-03

This aluminum rear lower suspension arm is specified for the Tamiya DT-03 chassis and is offered as a metal alternative to the original plastic arm. The part is intended for builders who need a direct-fit replacement for DT-03 rear lower arms and want a consistent mounting point during setup and tuning.

Installation is straightforward for anyone familiar with DT-03 suspension work: remove the stock part, transfer any necessary pins or spacers, and fit the aluminum arm in the original locations using the existing hardware. Because this is an RC-scale replacement part, verify fitment on your chassis before full reassembly.

In a tuning workflow the rear lower arm serves as a fundamental mounting surface for wheel geometry, roll center and rear track width adjustments, so using a stable metal arm helps maintain setup while experimenting with shocks, toe and camber settings.

Select this arm when you need a metal replacement that preserves DT-03 suspension geometry for setup work and routine maintenance.
