LUK F-Body Master Cylinder. Made in the USA. Other master cylinders have been known to cause problems with the SSM clutch pedal kit because the pushrod is not held to very tight tolerances. They have been known to crimp them on too short, not allowing the master to fully stroke and release the clutch. Don’t waste time with cheap copies, go with this OEM supplier. Includes the remote reservoir hose, outlet seal and retaining pin. Ships in the SSM pedal kit package.
