The Serpent 904211 Midshaft brings precision engineering to the S990E driveline, smoothing torque delivery and reducing drivetrain lash. Its tighter tolerances make it a useful upgrade for club racers and workshop tuners seeking consistent response.
Designed to seat correctly in the S990E chassis, this midshaft balances strength with accurate alignment. It integrates with the existing driveline to help protect bearings and gears from uneven loading during spirited running.
