This RC-scale aluminum 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 serves as a direct replacement for the rear arm/gearbox support location and is intended for hobby-level chassis maintenance and rear-end tuning.
Engineered to offer a firmer mounting point than common plastic replacements, the part helps stabilise rear suspension geometry and supports the gearbox during hard cornering and landing from jumps. Installing an aluminum support can help the chassis retain alignment under load and create a more predictable response when adjusting setup.
Installation notes: the component mounts to the stock B8 part positions on the listed Tamiya chassis; confirm hole alignment and clearance on your own model before final assembly. Retain original hardware if you plan to reuse it and verify fit with your suspension pins and linkages. No extra tools or replacement hardware are supplied with this item.
