This gun metal aluminum front suspension arm mount and gearbox support is catalogued JR-TFD08-GU as an RC-scale A5 replacement for compatible TAMIYA chassis. It is produced to match the A5 mounting footprint found on those vehicles.
The part is suitable for TAMIYA Thunder Shot, Thunder Dragon, Fire Dragon, and Terra Scorcher models where the A5 mount applies, offering a firm pivot point for suspension arms and a support location for the gearbox during setup and maintenance.
Installation: align the mount in the A5 position on the chassis and secure with the original fasteners where appropriate. Verify pivot alignment, gearbox engagement, and steering clearance before applying final torque to fasteners.
Tuning role: this component maintains repeatable pivot geometry to aid toe, caster, and shock travel adjustments on the supported TAMIYA models.
