ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.\u003c\/p\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eLight to moderate pedal effort, smooth positive engagement, OE to mild gear rattle\u003c\/li\u003e\n\u003cli\u003eLonger friction life, extended by ACT's exclusive diaphragm design\u003c\/li\u003e\n\u003cli\u003eCarefully engineered, precisely assembled, accurately balanced, with premium organic friction materials for heat tolerance and reduced fade\u003c\/li\u003e\n\u003cli\u003eRecommended for street and race use\u003c\/li\u003e\n\u003cli\u003e100% clamp load tested and dynamically computer balanced for smooth high RPM reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eClutch Master Cylinder Included: No \u003c\/li\u003e\n\u003cli\u003eGrease Included: Yes \u003c\/li\u003e\n\u003cli\u003eGrade Type: Performance \u003c\/li\u003e\n\u003cli\u003ePilot Bushing Included: Yes \u003c\/li\u003e\n\u003cli\u003ePressure Plate Type: Heavy Duty \u003c\/li\u003e\n\u003cli\u003eRelease Bearing Included: Yes \u003c\/li\u003e\n\u003cli\u003eClutch Disc Diameter: 8.8 in\u003c\/li\u003e\n\u003cli\u003eClutch Disc Diameter: 224 mm\u003c\/li\u003e\n\u003cli\u003eDisc Material: Organic \u003c\/li\u003e\n\u003cli\u003eInput Spline Quantity: 24 \u003c\/li\u003e\n\u003cli\u003eInput Shaft Diameter: 1 in\u003c\/li\u003e\n\u003cli\u003eAlignment Tool Included: Yes \u003c\/li\u003e\n\u003cli\u003eDisc Type Sprung Solid: Sprung \u003c\/li\u003e\n\u003cli\u003ePressure Plate Bolts Included: No \u003c\/li\u003e\n\u003cli\u003eClutch Slave Cylinder Included: No \u003c\/li\u003e\n\u003cli\u003eFlywheel Bolts Included: No \u003c\/li\u003e\n\u003cli\u003eProduct Weight (lbs.): 15 \u003c\/li\u003e\n\u003cli\u003eTorque Capacity (ft\/lbs.): 305 \u003c\/li\u003e\n\u003cli\u003eTorque Capacity Over OE: 0.36 \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReferences\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInstallation Instructions\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c!-- tt-ap-content v1 --\u003e","brand":"ACT Clutch Kits \u0026 Flywheels","offers":[{"title":"Default Title","offer_id":67806442848575,"sku":"MAP ACT NS4-HDSS","price":493.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1639\/5151\/files\/ACT-Clutch-Kits-Flywheels-Advanced-Clutch-HDPerf-Street-Sprung-Kit-NS4-HDSS.webp?v=1792430707","url":"https:\/\/www.mobileigo.com\/en-au\/products\/act-clutch-kits-flywheels-advanced-clutch-hd-perf-street-sprung-kit-ns4-hdss","provider":"mobileiGo.com","version":"1.0","type":"link"}
