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

DT-03 Rear Lower Suspension Arm Overview

This machined aluminium rear lower suspension arm is offered as a direct replacement for Tamiya DT-03 chassis owners requiring a more rigid rear mounting point. The aluminium build replaces the stock plastic arm to limit unwanted flex and to support consistent geometry under different setup conditions.

Installation uses the original DT-03 pivot and mounting layout so existing pins and fasteners fit. Verify alignment and pin retention after installation and recheck fastener torque following the first sessions. The component is focused on improving chassis feedback during setup fine tuning rather than altering core suspension design.

Practical notes: this arm is suited when you need repeatable pivot stiffness for rear toe and camber work, or when replacing a degraded plastic arm. Small adjustments to shocks or servo endpoints can help maintain predictable handling after the upgrade.

This precision aluminium arm is a straightforward solution for wear replacement and for gaining a firmer rear mounting point during DT-03 suspension tuning.
