{"product_id":"racing-lightweight-billet-chromoly-steel-flywheel","title":"Racing Lightweight Billet Chromoly Steel Flywheel","description":"The Exedy EF503 is a lightweight racing flywheel engineered to enhance engine response and acceleration in performance vehicles. Constructed from a solid, one-piece billet chromoly steel forging, it significantly reduces rotational mass and inertia compared to stock flywheels.\n\nIt features integrated ring gear teeth for increased durability and is heat-treated to prevent warpage, ensuring a long service life. The EF503 is burst-tested and SFI 1.1 approved, making it legal for competition where such certifications are required or recommended.\n\nThe Exedy EF503 flywheel is compatible with the stock clutch disc and pressure plate, simplifying installation. It is an ideal upgrade from heavy, cumbersome OEM dual-mass flywheels, offering a more responsive feel and potentially saving costs associated with replacing complex stock components. The design also incorporates fins to enhance airflow and clutch cooling, contributing to better performance under stress.\n\nThis flywheel is exclusively designed for vehicles with a 6-bolt crankshaft. It is listed as fitting various Ford Mustang models from 1996 to 2016 with 4.6L or 5.0L V8 engines, including specific trims like Mach 1, Boss 302, Bullitt, GT, SVT Cobra, and Shelby GT.","brand":"Exedy","offers":[{"title":"Default Title","offer_id":52687983706424,"sku":"EF503","price":419.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664708533.jpg?v=1784888543","url":"https:\/\/store.motormia.co\/products\/racing-lightweight-billet-chromoly-steel-flywheel","provider":"MOTORMIA","version":"1.0","type":"link"}
