This aftermarket RC component provides front and rear upper arms for use with TAMIYA Thunder Shot, Thunder Dragon and Fire Dragon chassis, supplied as a pair in black. The parts are machined aluminum intended to fit the vehicle's existing mounting points as a direct upgrade over plastic.
Installation guidance: the arms are designed to substitute factory plastic arms and typically mount at the same hinge locations and with the same hardware. No extra tools are required in most cases; verify the original pins and screws for reuse where compatible.
Tuning notes: using aluminum upper arms increases structural stiffness relative to stock plastic, which can alter suspension dynamics and feedback. Incorporate them into a setup aimed at reducing arm flex and refining response while keeping other suspension geometry in mind.
