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.
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.
