The Clutch Masters 850 PRO Series Twin Disc Clutch Kit is engineered for high-performance street and track applications, offering exceptional durability and reliable engagement for Nissan Skyline models equipped with RB25DET and 2.6L RB26DETT engines from 1989 to 1998. Featuring a unique multi-disc design, this clutch system combines a sprung ceramic disc (PTD80) with a rigid ceramic disc (PTD8R) to deliver optimal torque handling, smooth engagement, and enhanced heat resistance. The kit’s construction utilizes high-quality ceramic friction materials that withstand intense abuse, making it ideal for motorsport enthusiasts and heavy-duty fleet operators alike. The 8.50-inch (216mm) diameter clutch assembly is designed with a next-generation 12-point stud and nut mounting system, replacing traditional six-post configurations for superior structural integrity and resistance to flex, wear, and failure under extreme conditions. The re-engineered driven hub employs a single, precision-driven hub instead of multiple contact points, simplifying installation and ensuring consistent, even engagement with the transmission input shaft. This reduces spline wear and enhances reliability during high-torque operation. Specifically built to work exclusively with Clutch Masters flywheels, this conversion kit does not fit OEM flywheels, ensuring optimal performance and safety. The kit’s twin disc rigid configuration allows for quick, responsive power delivery while maintaining smooth pedal feel, making it suitable for aggressive street driving or competitive motorsport environments. All components meet or exceed industry standards, with the clutch kit and flywheel being SFI Certified, ensuring compliance with automotive and motorsport performance regulations. Designed for heavy-duty use, this clutch system provides a dependable upgrade for Nissan Skyline owners seeking maximum performance and fleet-level durability.
