{"product_id":"lsj-modular-pulley","title":"LSJ Modular Pulley","description":"If you do not already have the Modular Hub, the complete Modular Pulley System must be purchased. These pulleys are engineered specifically for Ecotec engines. While ZZP has tested sizes as small as 2.7\", they guarantee fitment down to 2.8\" without requiring snout machining, as each snout is cast and machined differently.\n\nRecommended pulley sizes are provided based on octane ratings and associated modifications. For example, a 3.1\" pulley is recommended for 42# injectors, a 3.0\" for a Stage 2 Kit and ZZP Downpipe, and larger modifications like Stage 3 kits, 60# injectors, and ported heads may utilize sizes down to 2.6\".\n\nA product note specifies that the 2.9\" pulley has a slightly different, matte\/satin anodized finish compared to other sizes. These pulleys come with 8 ribs, and the recommended bolt torque spec is 72 inch-pounds.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52867024257336,"sku":"ZZ-LSJMPS-30","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687424618.webp?v=1787910097","url":"https:\/\/store.motormia.co\/products\/lsj-modular-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
