This RC aluminium rear suspension arm mount and gearbox support is supplied as the B8 parts set for Tamiya Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher chassis. It acts as a direct replacement location for the rear arm/gearbox support to assist with tuning and maintenance tasks.
The stiffer aluminium mount aims to reduce flex compared with generic replacements, helping to stabilise rear geometry and support the gearbox during heavy cornering and landings. That stability aids in tuning decisions by making changes more predictable under load.
Fitting notes: the unit installs at the stock B8 positions on the listed Tamiya models; always check hole alignment and clearance on your own chassis before final assembly. Retain or match original hardware and confirm compatibility with your suspension pins and linkages. The item is sold without extra mounting hardware or tools.
