{"product_id":"heavy-duty-race-sprung-4-pad-clutch-kit","title":"Heavy Duty Race Sprung 4-Pad Clutch Kit","description":"The ACT SB11-HDG4 is a Heavy Duty Race Sprung 4 Pad Clutch Kit, designed as a conversion kit to replace the original 230mm clutch with a 240mm unit. Each diaphragm undergoes a rigorous four-stage heat-treating process for exceptional performance and durability.\n\nThe included 4-pad spring-centered race disc is constructed from select ceramic friction materials, offering high heat tolerance and maximum performance suitable for high horsepower street or race applications. This disc design is well-suited for smaller engines and smaller disc sizes. While providing faster shifting, the 4-pad design results in a harsher engagement compared to other disc types. The kit also comes with a Streetlite flywheel, and all necessary pressure plate bolts (M8-1.25 x 16mm) are included.\n\nImportant compatibility notes: This kit replaces the original 230mm clutch and requires the use of the included ACT Flywheel. Subaru began incorporating 240mm clutch components into production starting mid-2018 (VIN J806877 and later). ACT clutch kits and flywheels are not compatible with these revised OEM components. The kit offers a torque capacity of 574 ft-lbs, which is approximately 78% over stock.\n\nWith its 100% clamp load testing and dynamic computer balancing, the ACT SB11-HDG4 ensures smooth high RPM reliability. The pedal effort is light to moderate, with aggressive engagement and potentially OE to mild gear rattle. ACT provides a 12-month warranty for this clutch kit.","brand":"ACT (Advanced Clutch Technology)","offers":[{"title":"Default Title","offer_id":52686758019384,"sku":"SB11-HDG4-ACT","price":1226.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178782.jpg?v=1784876390","url":"https:\/\/store.motormia.co\/products\/heavy-duty-race-sprung-4-pad-clutch-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
