{"product_id":"heavy-duty-performance-street-sprung-clutch-kit-2","title":"Heavy Duty Performance Street Sprung Clutch Kit","description":"The ACT MB1-HDSS kit combines ACT's popular Heavy Duty pressure plate with their most popular street disc for a robust performance upgrade. The Heavy Duty pressure plate is engineered with an exclusive diaphragm design that boosts clamp load, minimizes deflection, and extends clutch life. ACT's diaphragms undergo a rigorous four-stage heat-treating process for reliable performance. Precision cover stampings ensure rigidity and consistent operation.\n\nThe Performance Street disc is constructed with premium organic friction materials offering high copper content for superior heat transfer. A steel-backed lining enhances burst strength and overall durability. This disc also features a reduced marcel for quicker shift action, complementing the pressure plate's capabilities with increased strength and reliability.\n\nSpecifications for this kit include a 320 ft-lb torque capacity (a 27% increase over OE), an 8.8-inch (224mm) clutch disc diameter, and a 0.875-inch input shaft diameter. It is recommended for both street and race use, offering longer friction life and 100% clamp load testing with dynamic computer balancing for smooth high-RPM reliability. The kit includes a 12-month warranty.","brand":"ACT Heavy","offers":[{"title":"Default Title","offer_id":52686763163960,"sku":"MB1-HDSS","price":475.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671539.jpg?v=1784876448","url":"https:\/\/store.motormia.co\/products\/heavy-duty-performance-street-sprung-clutch-kit-2","provider":"MOTORMIA","version":"1.0","type":"link"}
