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

Aluminum rear lower arm for DT-03

This aluminum rear lower suspension arm is designed specifically for the Tamiya DT-03 chassis as a robust metal alternative to the stock plastic part. It provides a consistent mounting point for competitors and hobbyists seeking repeatable setup on track.

Installation is straightforward for those familiar with DT-03 suspension work: remove the original arm, carry over any pins or spacers you need, and locate the aluminum arm in the OE positions using the existing fasteners. Always check alignment and clearances before final reassembly.

During setup the rear lower arm forms a fixed reference for wheel geometry, roll center and rear track width adjustments, so a stable aluminum arm helps preserve settings while testing shocks, toe and camber changes.

Choose this arm when you want a metal replacement that keeps DT-03 suspension geometry stable for tuning and routine maintenance.
