{"product_id":"heavy-duty-performance-street-sprung-clutch-kit","title":"Heavy Duty Performance Street Sprung Clutch Kit","description":"The ACT SB9-HDSS Heavy Duty Performance Street Sprung Clutch Kit combines ACT's most popular Heavy Duty pressure plate with their performance street disc, designed for reliable street and light race performance. The pressure plate utilizes an exclusive diaphragm design that increases clamp load and reduces deflection for maximum clutch life, with all diaphragms undergoing a four-stage heat-treating process.\n\nThe Performance Street disc features premium organic materials with high copper content for superior heat transfer and steel-backed lining for enhanced burst strength and durability. It includes a reduced marcel for faster shifting action.\n\nIncluded with the kit is ACT's patented Monoloc, a one-piece replacement for standard two-piece wedge collars and wire rings in pull-type clutches. Constructed from hardened chrome-moly steel, Monoloc provides uniform loading on the bearing and pressure plate for proper alignment under various driving conditions. The clutch assembly is 100% clamp load tested and dynamically computer balanced to within .25 oz-in for smooth high RPM reliability, exceeding stock production clutch balance tolerances.\n\nInstallation requires a break-in period of 300-500 miles for organic street discs, focusing on mild engagement to avoid overheating and potential surface damage. This clutch kit is recommended for street and race use, offering enhanced torque capacity. The kit is backed by a 12-month warranty. Specific fitment includes various Subaru Legacy, Impreza, and Baja Turbo models with specific engines and turbocharged configurations.","brand":"ACT","offers":[{"title":"Default Title","offer_id":52686759985464,"sku":"ACTSB9-HDSS","price":777.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661654981.webp?v=1784876410","url":"https:\/\/store.motormia.co\/products\/heavy-duty-performance-street-sprung-clutch-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
