{"product_id":"serpentine-performance-ratio-pulley-set","title":"Serpentine Performance Ratio Pulley Set","description":"The Steeda Underdrive Pulleys (555-3305) are a performance-enhancing upgrade designed for various Ford Mustang models. These serpentine-style pulleys are manufactured with a performance ratio to reduce parasitic power loss by slowing down the accessories driven by the serpentine belt. The result is a slight increase in horsepower and potential for longer accessory life.\n\nInstallation of these underdrive pulleys has been documented for 2001-2004 Mustang GTs with the 4.6L 2V engine, as well as 2005-2010 Mustang GT models. Some users have reported positive experiences, noting that they free up a few horsepower and contribute to better accessory performance.\n\nWhile generally well-received, some forum discussions have touched upon potential concerns, including discussions about oil pump failures in relation to underdrive pulley installations. However, other users have reported no such issues.","brand":"Steeda","offers":[{"title":"Default Title","offer_id":52663834476856,"sku":"555-3305","price":169.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687714801.jpg?v=1784330024","url":"https:\/\/store.motormia.co\/products\/serpentine-performance-ratio-pulley-set","provider":"MOTORMIA","version":"1.0","type":"link"}
