Aftermarket Rear Lower Arm for DT-03

This aluminium rear lower suspension arm is an RC-scale aftermarket replacement made for the TAMIYA DT-03 chassis. Intended as a direct aluminium alternative to the stock plastic arm, it provides a stiffer mounting point for the rear suspension and is for hobby use only.

Fitment is aimed at the DT-03 rear lower position and relies on the chassis' existing mounting geometry and fasteners. Installation generally follows standard arm removal and refit steps and requires only common hobby hex drivers and screwdrivers.

Specifications

Use this arm to increase durability and reduce flex at the rear lower mount when setting up DT-03 suspension tuning on the track or for hobby maintenance.

No special machining is needed for standard DT-03 mounts; clean the mounting area and use the chassis' existing fasteners unless they are damaged.
Occasionally worn or stripped screws should be replaced to ensure a secure fit with the aluminium arm; otherwise the original hardware normally suffices.
Expect reduced rear flex and a more consistent suspension response, which can improve predictability when adjusting setup settings.
Yes, it is designed for hobby track and recreational competition where the DT-03 chassis is used, offering better repeatability than the stock plastic part.
