TAMIYA DT-03 Aluminum Front Lower Suspension Arm (Red) - JR-DT300-RD by Jazrider  [JR-DT300-RD]

Function and fitment overview

This aluminum front lower suspension arm is an RC-grade replacement made to fit the TAMIYA DT-03 chassis. It installs in place of the stock plastic arm to retain factory steering geometry while giving a metal option for those who prefer a stiffer mounting point.

The part is described in the title as aluminum with a red finish; this provides greater rigidity compared with molded plastic and helps maintain alignment under heavier loads or when paired with upgraded components. It is intended for maintenance and routine replacement, not to alter chassis geometry beyond factory limits.

Installation follows standard DT-03 service steps: remove the wheel and hub, free the lower-arm fasteners, swap the arm while keeping existing bushings or bearings, and reassemble with the original hardware. After fitting, check for clearance and confirm the steering linkages move freely through full suspension travel.

Choose this arm to replace worn plastic pieces or when a metal component is preferred for consistent handling and easier servicing; verify torque settings and fit during installation.
