Clutch Masters 02029PTD8RS FX850 PRO Twin Disc Clutch Kit Sprung Race Steel Flywheel

The Clutch Masters FX850 PRO Series Twin Disc Clutch Kit represents the next evolution in multi-disc clutch performance. Part number 02029-PTD8RS features an 8.50" (216mm) twin disc assembly engineered to bridge the gap between pure motorsport racing technology and demanding high-performance street and track applications. This kit includes a steel flywheel and is configured in the Sprung Race stage, featuring one sprung ceramic disc directly connected to a second ceramic disc for optimized engagement characteristics.

FX850 PRO Series Key Features:

• 8.50" (216mm) twin disc assembly — a larger diameter platform designed specifically for high-horsepower applications
• Sprung Race (PTD8RS) configuration — 1 sprung ceramic disc directly connected to a second ceramic disc for controlled, consistent engagement
• 12-point nut and stud mounting system — replaces the traditional 6-post aluminum setup with a 12-post, heat-treated steel foundation for unmatched structural integrity
• Next-generation single driven hub design — precision-driven hub enables faster installation, cleaner alignment, and constant even engagement with the transmission input shaft, reducing spline wear
• Billet aluminum cover assembly — machined to minimize flex (only .003" vs. up to .030" on cast or stamped units), maximizing clamping force and driver consistency
• Steel flywheel included — precision manufactured and zero-balanced for true, vibration-free operation
• SFI certified — clutch kits and flywheels meet SFI performance standards for motorsport competition
• Higher holding capacity — the 850 Series delivers greater torque capacity, less clutch chatter, and smoother engagement versus smaller diameter twin disc systems
• Average 50% increase in clamping force — achieved by increasing pressure plate clamping force and expanding usable disc surface area
• Components available separately — for cost-effective future repair and maintenance

The FX850 PRO Series is built for drivers who demand maximum performance without sacrificing drivability. With ceramic friction materials rated for serious abuse, positive release for high-RPM staging and shifting, and custom friction surface options available, this twin disc system is a proven upgrade for high-output engines in both track and spirited street environments.
