Clutch Masters 1000 Series Twin Disc Clutch Kit with Steel Flywheel for 1JZ with R154
Even with basic bolt on mods the 1JZ motor, using the R154 transmission, the stock clutch becomes incapable of supporting the upgrades and more aggressive driving from track days. The 1000 series twin disk clutch is rated for around 1000 horsepower and is a must have to put the power to the ground for any track ready 1JZ using an R154 transmission, while also shaving rotating mass from your engine!
This 1000 series kit is a 10″ (254mm) twin disc clutch with a custom cover plate that is machined from billet aluminum and is then Type 3 hard anodized. By machining the strongest cover possible while maintaining minimal weight, Clutch Masters was basically able to eliminate any flex in the cover. The billet covers see only .003″ of flex where as a cast or stamped unit can see as much as .030″ of flex. By eliminating this flex in the cover, the driver is able to operate the clutch much more consistently and confidently. The strength of the covers also results in greater clamping force over the same amount of area vs a cast or stamped cover. This means the disc’s are easy to drive and have superior clamping force to make sure all the power your engine is making is being utilized.
What makes the 1000 kits truly special, and a feature unique to Clutch Masters is the QR System, or Quick Release Pressure Plate. The QR System Incorporates three spring-loaded bolts allowing the pressure plate to engage and disengage evenly and smoothly while reducing internal clutch noise/chatter by up to 50%. The QR System was developed to provide quiet and smooth operation for the user while delivering the performance a race clutch needs.
