The Clutch Masters FX850 Series 10306-TD8R-S is an 8.5-inch (216mm) twin disc race clutch kit designed for high-horsepower applications in vehicles with smaller bell-housings. This complete kit includes an aluminum flywheel, making it a comprehensive solution for performance enthusiasts seeking ultimate power handling capability.

Race Configuration (TD8R):

• Features one sprung ceramic disc and one ceramic rigid disc for maximum grip and durability
• 8.5-inch diameter twin disc assembly provides superior holding capacity with reduced clutch chatter
• Billet aluminum cover assembly with Type 3 hard anodizing for 25% more tensile strength than cast units
• Engineered to hold tremendous horsepower and torque while maintaining reasonable pedal pressure
• Includes release bearing for complete installation

Advanced Engineering Features:

• QR System (Quick Release Pressure Plate) with three spring-loaded bolts for smooth, even engagement
• Billet 6061-T6 aluminum flywheel machined to meet SFI spec 1.2 for NHRA, NDRA, IDRC, IHRA, SCCA, and NASA competition
• Replaceable heat shield included with aluminum flywheel

• Over 50% lighter than OEM assemblies for improved throttle response

The FX850 Series represents pure racing technology that also performs exceptionally well in high-performance street applications. By increasing clamping force and usable disc area, this twin disc system significantly increases torque capacity with only an average 50% increase in pedal pressure, making it manageable for track use while delivering race-level performance.
