The Serpent 902133 Servo-saver Shaft Inner is a replacement component for 1/10 scale RC vehicles, meant to bring back firm and predictable steering. Its straightforward design makes it a sensible swap when steering becomes loose or less responsive.
As part of the servo-saver mechanism, the inner shaft reduces slack and helps the steering follow servo input more faithfully. Replacing worn parts helps maintain consistent handling and makes tuning more effective.
