{"product_id":"3-piece-underdrive-pulley-kit","title":"3-Piece Underdrive Pulley Kit","description":"The SR Performance Underdrive Pulleys are a 3-piece kit designed to reduce parasitic drivetrain loss, freeing up an estimated 10-15 horsepower without compromising essential cooling and charging functions. These pulleys are CNC-machined from lightweight, aircraft-grade aluminum alloy for superior strength and durability. The black powder-coated finish not only provides an aggressive aesthetic but also ensures long-lasting corrosion resistance.\n\nInstallation is designed to be straightforward, typically completed in under 2 hours with no modifications required. This kit reuses the factory belt. It is specifically engineered for late 2001 to 2004 GT Mustangs equipped with the SOHC 4.6L V8 engine and a short water pump (identified by a bowed-in face).\n\nA technical note highlights a design change in the 4.6L engine's water pump for the 2001 model year. Earlier pumps (1996 to mid-2001) had a longer shaft, while newer pumps (January 2001 onwards) feature a shorter shaft, necessitating a specific pulley design. This SR Performance kit is confirmed to fit GT Mustangs with the short water pump and a bowed-in pulley face.","brand":"SR Performance","offers":[{"title":"Default Title","offer_id":52663805804856,"sku":"525575","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687137994.webp?v=1784329803","url":"https:\/\/store.motormia.co\/products\/3-piece-underdrive-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
