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

DT-03 rear lower component summary

This red aluminum rear lower suspension arm is offered as an aftermarket upgrade for the Tamiya DT-03 chassis, replacing the OEM plastic arm with a more rigid metal option. It is aimed at users who need reliable mounting geometry for setup consistency.

Installation is similar to the original part: remove the stock arm, transfer any retaining pins or spacers, and mount the aluminum arm at the factory locations using the existing fasteners. Verify hole alignment and fit prior to final assembly.

Because it provides a firmer reference point for suspension mounting, the arm supports stable wheel geometry and helps preserve tuning settings while you experiment with shocks, toe and camber adjustments.

Ideal when you require a metal replacement that retains DT-03 suspension geometry for precise tuning and dependable maintenance.
