QSC Stage 1 clutch kit is designed for high performance street application. It provides a smooth engagement and an extended clutch life. Our clutch systems are engineered to maximize the durability and stability, and they can be easily installed without modification. This Stage 1 clutch kit includes a heavy-duty pressure plate, premium organic disc, throw out bearing, pilot bearing, flywheel, and alignment tool

Pressure Plate

QSC pressure plates are engineered to maximize the clutch life. The clamp loads are 35% to 60% higher than stock. The diaphragms of each pressure plate endure a four stage heat treated process to improve tension strength while preserving the structural integrity. All QSC pressure plates are CNC precision machined and computer balanced to ensure smooth operation. Each pressure plate also features heavy-duty drive straps and rivets to secure the contact face.

Clutch Disc

QSC stage 1 clutch disc is made of premium organic friction material. The organic friction materials enables more efficient heat transfer, and it also provides a good frictional surface for high performance street use. This stage 1 is designed to maximized the clutch life.


QSC forged flywheels are made of high quality chrome-moly steel. They are stronger, lighter, and more heat and corrosion resistant than stock. Our flywheels are engineered to reduce MOI (Moment of inertia) and thus provide a better engine response. They are also designed to increase air flow to enhance the overall thermal performance of the clutch system. All of our flywheels are CNC machined to ensure perfect balancing and to provide a flat surface for clutch disc bedding. In addition, the surface of the flywheels is designed to fit any kind of clutch disc material, ranging from organic to ceramic. All of the above make QSC flywheel an ideal choice for street or track applications**
