These JAZRIDER upper arms are a straightforward durability upgrade for Tamiya Thunder Shot, Thunder Dragon and Fire Dragon models. The aluminium construction reduces flex compared to stock plastic arms and helps the vehicle retain setup during everyday running and rougher use.
Manufactured to give consistent fitment, the JR-TFD04-BK arms provide reliable mounting points and preserve factory geometry. They are intended for hobbyists who value low-maintenance, long lasting parts that improve handling without complex tuning.
Installation is a direct replacement for the original upper arms on compatible Tamiya models and requires only common RC tools. Inspect existing hardware before reuse and replace any worn pins or screws for best results.
