The Serpent SER903782 Servo Saver Shaft Inner for the S989 is a practical replacement part that helps restore sharp steering response. It is manufactured to align with the S989 steering components for reliable fitment.
Installing this shaft removes excess play and returns cleaner input from the servo to the wheels. It is suitable for track days and general maintenance alike where steering precision matters.
Installation is simple with standard tools; take the opportunity to inspect adjacent parts like the servo horn and link rods. Keep moving parts clean and lightly lubricated to minimise wear.
