{"product_id":"2-9-inch-modular-supercharger-pulley","title":"2.9-Inch Modular Supercharger Pulley","description":"The ZZPerformance ZZ-6LSJMP-2.9-BLK is a 2.9-inch diameter modular supercharger pulley, offered in a black finish. When installed, a smaller diameter pulley causes the supercharger to spin faster, generating more boost.\n\nThis 2.9\" pulley is specifically recommended for use with a Stage 3 Kit, 60# injectors, a Dual Pass End plate, and a Header\/Down pipe combination, ideally on 93 octane fuel. ZZPerformance notes that their Ecotec specific pulleys can function down to 2.7\" without snout machining, but they only guarantee down to 2.8\" without modifications due to variations in snout casting and machining. A product note indicates that the 2.9\" pulley may have a matte\/satin finish, differing slightly from other sizes.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52689675026744,"sku":"ZZ-6LSJMP-2.9-BLK","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687424228.webp?v=1784909031","url":"https:\/\/store.motormia.co\/products\/2-9-inch-modular-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
