QSC Stage 3 clutch kit is designed for high horsepower street or race application. It provides an aggressive engagement and low to moderate gear rattle. Our clutch systems are engineered to deliver high performance while maintaining durability, and they can be easily installed without modification. This Stage 3 clutch kit includes a heavy-duty pressure plate, premium ceramic disc, chromoly flywheel, throw out bearing, alignment tool, slave cylinder with release bearing, and pilot bearing

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 6 puck clutch disc is made of ceramic pads with high coefficient of friction. It enables quick engagement and performs reliably for extreme duty friction applications. The 6 spring designs also boosts the overall power and durability of the disc. This 6 puck disc is engineered to deliver high torque and holding capacity, and it is ideal choice for the serious enthusiasts.

Flywheel

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**

Looks great buy too short
Color: Red, Size: 4X-Large
Purchased for my son for a Christmas event at his job. He is 330pds and 6ft tall so I got the 4xl for him. It's fits perfectly in width BUT it's short. I know because he is tall I should have searched for a 4XLT but could not find one in the colors needed. But I purchased a white 4xlt tee for him to wear underneath and leave the shirt open it's looks great. So great shirt comfy and cozy well made and colors exactly as shown but if you are on the taller side maybe wear it as an over shirt with a tee underneath.

Well made, warm.
Color: Brown, Size: X-Large
A heavy yet soft flannel shirt. Nice on a foggy or light misty day. Flannel is a bit loosely woven but well sewn. Size reflects its lable. Its become a 'got to' shirt this fall.

Quality look
This is my second purchase of this shirt. Soft, thick, good quality. Usually worn open with a tee underneath. Sizing is normal and a good length. But it could also be tucked in. Looks great!

Great shirt
Color: Khaki, Size: XX-Large, Color: Khaki, Size: XX-Large
Wonderful shirt. Bought this for my husband to wear for family photos and it fit great, wasn't scratchy and he was so comfortable in it he actually wears it to work sometimes even to this day. I would buy this brand again. It washed it before he wore it, I didn't notice any shrinking.
