Nissan 350Z Twin Disc Clutch Kit – Clutch Masters 850 PRO Series (2003-2006). A purpose-built twin-disc ceramic clutch and aluminum flywheel conversion for enthusiasts who demand confident engagement and repeatable performance.

Built on the FX 850 PRO 8.50 in (216 mm) platform, this kit replaces the old 6-post cover with a heat-treated steel 12-post, 12-point nut-and-stud system that resists flex, wear, and heat. The next-generation single driven hub speeds installation and provides cleaner alignment, maintaining consistent engagement with the input shaft to help reduce spline wear. Available as Sprung Race (PTD80: 1 sprung ceramic disc connected to a second ceramic disc) or Rigid Race (PTD8R: 2 ceramic discs with a rigid hub). Clutch Masters clutch kits and flywheels are SFI certified. This conversion is designed to work with the included Clutch Masters aluminum flywheel and will not fit the OEM flywheel.
