This aluminium rear suspension arm mount and gearbox support is provided as the B8 parts set for Tamiya Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher chassis. It is intended as an aftermarket replacement at the rear arm/gearbox support location for routine repairs and chassis upgrades.
The aluminium design aims to improve mounting rigidity over basic replacements, helping to keep rear suspension geometry and the gearbox area more stable when subjected to cornering loads and jumps. That stability can reduce alignment drift and aid consistent handling over multiple runs.
Fitment advice: attach the component to the stock B8 positions on the stated Tamiya platforms and confirm hole alignment and local clearances on your own model before tightening. Keep original hardware if suitable and check interaction with your suspension pins and linkages. The product is supplied without additional mounting hardware or tools.
