The JR-TFD08-RD item is an aluminium front suspension arm mount and gearbox support intended for 1/10-scale TAMIYA Thunder Shot, Thunder Dragon, Fire Dragon and Terra Scorcher buggies. It replaces the A5 plastic mount with a metal alternative to increase front-end stiffness and add reinforcement around the gearbox area while keeping the stock configuration.
Use case and fitting: this part installs into the factory A5 front bulkhead mounting points and links to the suspension arm pivot, maintaining original geometry. It is intended as a direct accessory for maintenance, tuning and to replace worn plastic parts without modifying the chassis or drivetrain.
Tuning notes: fitting an aluminium mount will alter front-end feedback and may change understeer/oversteer balance in combination with shock valving or sway bar changes. Inspect screws and mating faces during installation to ensure correct alignment and unobstructed suspension travel.
