This aluminum universal swing shaft set is an RC-scale drivetrain component specified for the TAMIYA TT-02 chassis. The light blue finish marks the set as an aluminum option designed to interface with the TT-02 drivetrain arrangement to help control alignment and lower unwanted movement during scale RC operation.
The components are made to mate with the TT-02's factory mounting points and drivetrain geometry, supporting uniform axle motion and helping the drivetrain transfer power with reduced slack. As this is an aftermarket accessory, check fitment on your chassis before installing and keep original fasteners if recommended.
Installation should emphasise alignment and driveline feedback rather than increased output. Installed shafts integrate with the gearbox and bearings to influence handling characteristics during setup and when driving.
