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

Precision rear lower arm for DT-03 tuning

This machined aluminium rear lower suspension arm is a direct-fit replacement intended for the Tamiya DT-03 chassis to aid tuning and routine maintenance. Its rigid construction replaces the original plastic arm to reduce flex and help keep suspension geometry steady across setup changes and different driving surfaces.

Fitment uses the DT-03 factory pivot and mount points, so standard pins and fasteners apply. After fitting, verify pin retention and alignment, and re-torque hardware following initial runs. The component focuses on improving chassis feedback during adjustment rather than altering the underlying suspension geometry.

Usage advice: install this arm when you require repeatable pivot stiffness for rear toe and camber tuning, or when replacing a worn plastic arm. Minor servo endpoint and shock tuning tweaks can help retain predictable handling after the swap.

Opt for this machined aluminium arm when you need a durable replacement or a firmer rear mounting point for suspension tuning on DT-03 models.
