{"product_id":"4-6l-underdrive-crank-pulley-kit","title":"4.6L Underdrive Crank Pulley Kit","description":"The Steeda underdrive pulleys are a precision-engineered performance upgrade for 2005-2010 Mustang GT models equipped with 4.6L engines. By reducing the rotational speed of engine accessories by approximately 25%, this system minimizes parasitic drag, which directly translates to gains in horsepower and improved fuel mileage. Unlike \"piggyback\" designs, this set features a one-piece nodular iron and injection-molded rubber crankshaft pulley specifically developed to withstand high underhood temperatures and provide proper torsional vibration dampening.\n\nThese pulleys are the only units of their kind developed through a partnership in Ford's technology transfer program, ensuring O.E.-level build quality and performance.\n\nInstallation requires specific hardware included with the kit, such as a 12mm x 60mm bolt used to start the new balancer pulley onto the crankshaft. Proper installation is critical, requiring the balancer to be torqued to 66 lb-ft. This product is compatible exclusively with 2005-2010 Mustang GT 4.6L engines; ensure your vehicle configuration matches these specifications before installation.","brand":"Steeda","offers":[{"title":"Default Title","offer_id":52663840440632,"sku":"701-0005-A","price":278.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687715089.gif?v=1784330066","url":"https:\/\/store.motormia.co\/products\/4-6l-underdrive-crank-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
