The aluminium front lower suspension arm mount is sold as JR-TBB03-BK for fitment to the TAMIYA BB-01 (BBX) platform. This metal replacement combats wear at the lower pivot and offers a more stable mounting reference than many stock plastic components.
Practically the mount stiffens the connection between lower arm and chassis, affecting front-end feedback and cornering precision on varied surfaces. The black finish suits scale styling while serving as a durable tuning part for BB-01 (BBX) kits.
Installation notes: check that the BB-01 (BBX) chassis hole spacing and fastener type correspond to this mount before installation, and retain or source suitable screws for JR-TBB03-BK to ensure secure fitting.
