The Clutch Masters FX850 strapped twin-disc clutch kit is specified for 2010–2017 Audi S4 B8 supercharged applications and ships with a steel flywheel. This conversion-style strapped cover kit requires Clutch Masters' flywheel and will not work with the OEM flywheel; it is intended for higher-capacity torque handling in modified drivetrain applications.
