For Tamiya DT-03 Rear Lower Suspension Arm — Aluminum Green JR-DT301-GR by Jazrider  [JR-DT301-GR]

Rear lower suspension arm — DT-03 upgrade

This machined aluminum rear lower suspension arm is a direct replacement tailored for the Tamiya DT-03 chassis to improve setup consistency. The aluminium construction replaces the flexible plastic original, offering a firmer mounting pad for the rear suspension to stabilise geometry when adjusting setups or running on varied surfaces.

Fitment uses the DT-03 factory pivot and mounting points so standard pins and fasteners are compatible. After the install, confirm pin retention and alignment, and retorque hardware after an initial run. The upgrade is intended to refine chassis feedback during tuning rather than to rework baseline suspension geometry.

Tuning advice: choose this arm to achieve repeatable rear pivot stiffness for toe and camber tuning, or when replacing aged plastic parts. Complement the change with small shock or servo endpoint tweaks to keep handling balanced.

Install this precision aluminium arm for a simple upgrade that tightens rear mounting for improved tuning feedback on DT-03 vehicles.
