28mm Toyota Supra JZA70 – 1JZGTE R154 Gearbox – R3C Clutch Kit
This race proven triple plate clutch kit features three 215mm full faced disks and has a recommended horsepower range of 800-1250whp (horsepower recommendation may vary per vehicle*). Our full faced clutch disk design allows for increased clutch modulation and drivability versus the commonly used puck style from other brands, which can result in a very on/off clutch feel. Many Supra owners have posted detailed product reviews stating that their OS Giken clutch retained an OEM feel and drivability, even in stop and go traffic!!!
All OS Giken clutches feature mono-piece, heat treated, lightweight steel flywheels. Unique to an OS Giken multiplate clutch is our 360 billet clutch housing, which provides an incredible amount of rigidity and durability to the entire clutch/flywheel assembly.
The triple plate clutch/flywheel assembly weighs in at 34 lbs, which is 36% lighter than the OEM single plate clutch/flywheel assembly. Understandably, the lighter assembly weight and smaller than OEM disks greatly reduces total rotating mass, resulting in quicker engine response and increased drivetrain efficiency!!!
