This is an RC-scale centre chassis mount for TAMIYA Scania R620 tractor truck models, supplied as a 3pcs alloy set TRU009SC. It is intended as a reinforcement and tuning component to increase rigidity through the midsection and to provide consistent attachment points for suspension and drivetrain linkages.
The alloy mount replaces stock plastic or weaker brackets to cut down on flex under load and to yield repeatable alignment during setup. The design targets use of the existing chassis holes and fasteners where possible to avoid extra drilling; confirm clearance and use thread locking on steel fasteners if recommended by your chassis instructions.
In tuning terms the mount offers a mechanical, low-risk improvement: by restraining mid-chassis deformation it helps maintain suspension geometry and driveline alignment when you adjust ride height, suspension travel or weight distribution for handling changes.
Install this mount where a robust centre-chassis support is needed for scale tractor truck setups, and check gearbox and suspension clearance before completing the installation.
