The T1SS-N04 doubles the organic friction surface area versus a single-disc setup, so it can handle high-power AWD applications while keeping pedal effort manageable. An exclusive four-stage heat-treating process on each diaphragm spring keeps the T1SS-N04 engagement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eT1SS-N04 uses a 225mm Mod-Twin pull-type design rated up to 875 ft-lb of torque capacity\u003c\/li\u003e\n\u003cli\u003eDoubled organic friction surface area compared to a single-disc clutch for high-power AWD use\u003c\/li\u003e\n\u003cli\u003eFour-stage heat-treated diaphragm springs for consistent, repeatable engagement\u003c\/li\u003e\n\u003cli\u003eSprung Mono-Drive hub absorbs drivetrain shock and reduces chatter\u003c\/li\u003e\n\u003cli\u003eIncludes a chromoly XACT Streetlite flywheel matched to the T1SS-N04 kit\u003c\/li\u003e\n\u003cli\u003eMaintains factory clutch stack height for a bolt-in installation\u003c\/li\u003e\n\u003cli\u003eExact ACT manufacturer part number T1SS-N04 for confident product matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\u003ctd colspan=\"4\"\u003eMatch the exact ACT MPN, vehicle, engine, transmission, clutch diameter, spline, and flywheel configuration before ordering.\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eVehicle fitment is a starting point.
