This aluminum VVC swing shaft bone is an optional performance upgrade specifically designed for the Kyosho RB7SS 2WD racing buggy. Constructed from high-strength, lightweight aluminum, it directly replaces the heavier stock steel shaft, effectively reducing the rotating mass within the vehicle's drivetrain. The reduction in weight enhances throttle response, improves acceleration, and contributes to more responsive suspension action, providing a tangible competitive advantage for serious racers aiming to optimize their vehicle's performance on the track.
