{"product_id":"stage-3-sprung-hub-clutch-kit","title":"Stage 3+ Sprung Hub Clutch Kit","description":"The SPEC Stage 3+ Sprung Hub Clutch Kit (SB533FS-NR) is a high-performance clutch solution engineered for BMW 135i, 335i (N54 engine), and 335d models manufactured between 2007 and 2012.\n\nThis clutch kit is ideal for enthusiasts seeking to handle significant power increases, such as those from hybrid or big turbo N54 builds, as well as for fast road cars, drag racing setups, and track day projects. It combines robust torque holding capabilities with a street-friendly pedal feel and precise engagement, transforming the driving dynamics of tuned BMWs.\n\nThe sprung hub design of the clutch disc offers smoother engagement and improved drivability compared to rigid discs used with solid flywheels. This feature helps to mitigate harshness, especially during take-up, providing a more compliant and controlled experience. The kit is rated to hold 671 ft-lbs of torque when fitted with a new MFactory flywheel.\n\nProfessional installation is recommended for this clutch kit. To ensure precise fitment, Nforcd will verify compatibility before dispatch and requests the customer's UK registration number or the last 7 digits of their VIN at checkout. The clutch is backed by a lifetime warranty from SPEC.","brand":"Spec Clutches","offers":[{"title":"Default Title","offer_id":52663752196408,"sku":"SB533FS-NR","price":1271.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687681082.jpg?v=1784329322","url":"https:\/\/store.motormia.co\/products\/stage-3-sprung-hub-clutch-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
