Clutch Masters has been engineering performance clutch systems in the United States since 1988. Their PRO Series twin-disc kits are developed and tested in-house, providing everything needed for a complete installation including flywheel, bearings, and hardware. Clutch Masters is trusted by drag racers, road racers, and high-output street builds across the globe.
The CLM06045PTD80S is the Clutch Masters 850 PRO Series twin-disc clutch kit with forged steel flywheel designed for the 1989-1998 Nissan Skyline with RB25DET or RB26DETT engines. It is rated at approximately 850 lb-ft of torque capacity and features SFI-certified components for race event compliance.
Does the CLM06045PTD80S fit both RB25DET and RB26DETT Skyline engines?Yes. The CLM06045PTD80S is engineered to fit both the RB25DET single-turbo and the RB26DETT twin-turbo versions of the 1989-1998 Nissan Skyline. Always confirm your specific transmission variant before ordering.
Does the CLM06045PTD80S include a flywheel?Yes. The S suffix in CLM06045PTD80S indicates the forged steel flywheel is included. The kit ships complete with the twin-disc clutch pack, forged steel flywheel, release bearing, pilot bearing, alignment tool, and hardware.
What is the torque rating of the CLM06045PTD80S?The 850 PRO Series is rated at approximately 850 lb-ft of torque capacity, making it suitable for highly modified RB26DETT builds with upgraded turbos, intercoolers, fueling, and engine internals pushing well beyond factory output.
Is the CLM06045PTD80S street drivable on a Skyline?The 850 PRO twin-disc has a more aggressive engagement profile than a stock or lower-stage clutch. Many Skyline owners use this system on the street, though you should expect a firmer pedal and quicker engagement point than stock. It is best suited for track-focused or high-powered builds.
Does the CLM06045PTD80S meet SFI certification requirements?Yes. Both the pressure plate and the forged steel flywheel included with the CLM06045PTD80S carry SFI certification, qualifying this system for sanctioned drag racing and road racing events with SFI drivetrain requirements.
What break-in is required after installing CLM06045PTD80S?Clutch Masters recommends a 500-mile break-in period avoiding hard launches and sustained clutch slip. Following the break-in procedure ensures the ceramic friction surfaces seat properly and maximizes longevity of the CLM06045PTD80S system.
How does the CLM06045PTD80S 850 PRO compare to the 725 PRO version for the Skyline?The CLM06045PTD80S 850 PRO offers higher torque capacity and more aggressive ceramic friction material than the 725 PRO version (CLM06045PTD7RS). If your Skyline is pushing well beyond 600-700 whp on a built RB26, the 850 PRO is the appropriate choice for maximum holding power and heat tolerance.
