The JR-TFD05-BK set provides two black aluminum lower suspension arms intended for front and rear use on selected Tamiya buggy platforms. These arms replace stock plastic items to stiffen the lower link and give a more predictable response during tuning changes.
Supplied as a two-piece black set, they are described for use on Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher chassis. They are positioned as upgrade parts to adjust roll stiffness and steering behaviour by cutting flex at the lower link while retaining compatibility with the original mounting points.
Installation notes: mount the arms in the stock lower-arm positions on compatible vehicles. Inspect hinge pins and retainers for wear and verify alignment after fitting. The package does not guarantee included hardware, so have the vehicle's existing fasteners ready before swapping components.
A practical aluminum alternative for builders wanting firmer lower arms on the listed Tamiya buggies while keeping the factory fitment points unchanged.
