The Xtreme pressure plate's diaphragm design increases clamp load and reduces deflection to extend clutch life, with every diaphragm undergoing ACT's four-stage heat-treating process and precision cover stampings for rigidity and consistency. The Performance Street disc uses premium organic friction material with higher copper content for improved heat transfer and steel-backed lining for greater burst strength, with reduced marcel for faster shift action and quiet, reliable operation. Monoloc is a one-piece, direct replacement for the standard two-piece wedge collar and wire ring used in pull-type clutches; its hardened chrome-moly construction provides uniform loading on the bearing and pressure plate for consistent alignment regardless of driver input or vehicle modifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePressure Plate: Xtreme, four-stage heat-treated diaphragm\u003c\/li\u003e\n\u003cli\u003eDisc: Performance Street, organic friction material, steel-backed lining\u003c\/li\u003e\n\u003cli\u003eRetaining Ring: ACT Monoloc, one-piece hardened chrome-moly (included)\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 16.4 lbs\u003c\/li\u003e\n\u003cli\u003eTorque Capacity: 511 ft-lb (50% over OE)\u003c\/li\u003e\n\u003cli\u003ePart Number: SB9-XTSS\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1991 Subaru Legacy Sport\u003c\/li\u003e\n\u003cli\u003e1992 Subaru Legacy Sport\u003c\/li\u003e\n\u003cli\u003e1993 Subaru Legacy Sport\u003c\/li\u003e\n\u003cli\u003e1994 Subaru Legacy Sport\u003c\/li\u003e\n\u003cli\u003e2002 Subaru Impreza WRX\u003c\/li\u003e\n\u003cli\u003e2003 Subaru Impreza WRX\u003c\/li\u003e\n\u003cli\u003e2004 Subaru Baja Turbo\u003c\/li\u003e\n\u003cli\u003e2004 Subaru Forester XT\u003c\/li\u003e\n\u003cli\u003e2004 Subaru Impreza WRX\u003c\/li\u003e\n\u003cli\u003e2005 Subaru Baja Turbo\u003c\/li\u003e\n\u003cli\u003e2005 Subaru Forester XT\u003c\/li\u003e\n\u003cli\u003e2005 Subaru Forester XT Premium\u003c\/li\u003e\n\u003cli\u003e2005 Subaru Impreza WRX\u003c\/li\u003e\n\u003cli\u003e2008 Subaru Legacy GT spec.B\u003c\/li\u003e\n\u003cli\u003e2009 Subaru Legacy GT spec.B\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWarning: This product can expose you to chemicals including carbon black, glass wool fibers, or silica (in clutch discs), chromium and nickel, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
