Tamiya DT-03 Compatible Rear Lower Arm, Aluminum (Red) - JR-DT301-RD by Jazrider  [JR-DT301-RD]

DT-03 rear lower suspension arm details

This red aluminum rear lower suspension arm fits the Tamiya DT-03 chassis and is offered as a durable aftermarket option to replace the original plastic component. It is aimed at drivers who want a firmer mounting surface for consistent setup repeatability.

Fitting is teacher-friendly for anyone used to DT-03 suspension maintenance: remove the stock arm, transfer required pins or spacers, then position the aluminum arm in the factory locations using the existing hardware. Perform a trial fit to verify clearances before final tightening.

For tuning, the rear lower arm is a primary datum for wheel alignment, roll center and rear track width; a rigid metal arm reduces variation when iterating shock and toe/camber adjustments.

Opt for this arm to secure more consistent suspension geometry during tuning sessions and maintenance checks.
