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

DT-03 rear lower arm information

This aluminum rear lower suspension arm is manufactured as an aftermarket replacement for the Tamiya DT-03 chassis, providing a stiffer alternative to the stock plastic part for improved stability during setup.

Installation follows the standard DT-03 procedure: remove the factory arm, reuse necessary pins and spacers, and secure the aluminum arm in the original mounting points with existing fasteners. Always confirm alignment before final assembly.

As a structural mounting surface, this arm helps lock in wheel geometry and reduces variance during tuning so adjustments to shocks and toe/camber remain consistent.

Select this arm when you need a compact, metal replacement that maintains DT-03 suspension geometry for both maintenance and competitive setup work.
