It replaces the factory clutch with a stronger, more durable street-oriented setup that holds up to 430 lb-ft of torque while retaining smooth, daily-drivable pedal feel. This kit is designed to be used exclusively with the Spec SF33A-4 billet flywheel (sold separately) and is not compatible with the stock flywheel or other Spec flywheels. It is the ideal upgrade for a lightly modified Focus ST that needs more clamping force than stock without sacrificing streetability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStage 1 non-ratcheting clutch kit for the 2012-2018 Ford Focus ST 2.0T EcoBoost\u003c\/li\u003e\n\u003cli\u003eRated for up to 430 lb-ft of torque\u003c\/li\u003e\n\u003cli\u003eHigh-carbon organic friction disc for smooth engagement and long life\u003c\/li\u003e\n\u003cli\u003eIncreased clamp-load pressure plate for improved holding power over stock\u003c\/li\u003e\n\u003cli\u003eRequires the Spec SF33A-4 billet flywheel; the stock dual-mass flywheel is not compatible\u003c\/li\u003e\n\u003cli\u003eDesigned for daily-driven, street-focused Focus ST builds\u003c\/li\u003e\n\u003cli\u003eSpec manufacturer part number: SF331-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThe SF331-4 must be installed together with the Spec SF33A-4 billet flywheel. If your Focus ST still has its factory dual-mass flywheel, you must order the SF33A-4 separately and install both at the same time. Installation requires removal of the transaxle and is best performed by an experienced technician. Always inspect the release bearing, pilot bearing, and slave cylinder during installation and replace as needed. Bed the clutch in with 300-500 miles of moderate, no-slip driving before applying full power.\u003c\/p\u003e\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eRequired Flywheel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2012-2018\u003c\/td\u003e\n\u003ctd\u003eFord\u003c\/td\u003e\n\u003ctd\u003eFocus ST\u003c\/td\u003e\n\u003ctd\u003e2.0T EcoBoost\u003c\/td\u003e\n\u003ctd\u003eSpec SF33A-4 billet flywheel (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eConfirm your vehicle is a 2.0T EcoBoost Focus ST for these model years before ordering.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSpec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part number\u003c\/td\u003e\n\u003ctd\u003eSF331-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStage\u003c\/td\u003e\n\u003ctd\u003eStage 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisc type\u003c\/td\u003e\n\u003ctd\u003eHigh-carbon organic, non-ratcheting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTorque capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 430 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRequired flywheel\u003c\/td\u003e\n\u003ctd\u003eSpec SF33A-4 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIntended use\u003c\/td\u003e\n\u003ctd\u003eStreet \/ daily driver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eWhat vehicles does the Spec SF331-4 fit?\u003c\/strong\u003e\u003cbr\u003eThe SF331-4 fits 2012-2018 Ford Focus ST models equipped with the 2.0T EcoBoost engine, when installed with the required Spec SF33A-4 billet flywheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the SF331-4 come with a flywheel?\u003c\/strong\u003e\u003cbr\u003eNo. The flywheel is not included.
