Like other Mod-Twin kits, the T2SS-N04 doubles the organic friction surface area of a single-disc clutch, so it manages torque through the factory AWD driveline without the abrupt engagement typical of a full race clutch. The T2SS-N04 pressure plate uses ACT's four-stage heat-treated diaphragm springs, engineered to hold consistent clamp force through repeated high-load cycles. A chromoly XACT Streetlite flywheel ships as part of the T2SS-N04 kit, matched to the clutch assembly so the whole rotating system is balanced and ready to install together.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eT2SS-N04 uses a 225mm Mod-Twin pull-type design rated up to 875 ft-lb of torque capacity\u003c\/li\u003e\n\u003cli\u003eExtreme Sprung Street clamp load, higher than the HD variant, for higher-output RB26DETT builds\u003c\/li\u003e\n\u003cli\u003eDoubled organic friction surface area for high-power AWD applications\u003c\/li\u003e\n\u003cli\u003eFour-stage heat-treated diaphragm springs for consistent clamp force\u003c\/li\u003e\n\u003cli\u003eIncludes a chromoly XACT Streetlite flywheel matched to the T2SS-N04 kit\u003c\/li\u003e\n\u003cli\u003eSprung Mono-Drive hub reduces driveline shock versus a rigid race disc\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1999-2002\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003eSkyline GT-R\u003c\/td\u003e\n\u003ctd\u003eR34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003eT2SS-N04\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClutch Diameter\u003c\/td\u003e\n\u003ctd\u003e225mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eMod-Twin pull-type, sprung disc, Extreme clamp load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTorque Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 875 ft-lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHub Type\u003c\/td\u003e\n\u003ctd\u003eSprung Mono-Drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlywheel Included\u003c\/td\u003e\n\u003ctd\u003eChromoly XACT Streetlite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine Application\u003c\/td\u003e\n\u003ctd\u003e2.6L Twin Turbo RB26DETT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmission\u003c\/td\u003e\n\u003ctd\u003e6-speed manual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1x T2SS-N04 Mod-Twin 225 XT Sprung Street clutch disc set and pressure plate assembly\u003c\/li\u003e\n\u003cli\u003e1x Chromoly XACT Streetlite flywheel\u003c\/li\u003e\n\u003cli\u003eClutch hardware, release bearing, pilot bearing, and alignment tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout ACT\u003c\/h4\u003e\n\u003cp\u003eAdvanced Clutch Technology (ACT) builds its Mod-Twin lineup, including the T2SS-N04, around modular twin-disc assemblies that let R34 GT-R owners select the clamp load matched to their power level.
