{"product_id":"3800-modular-pulley-system","title":"3800 Modular Pulley System","description":"The ZZP 3800 Modular Pulley System is designed to offer flexibility for performance tuning by allowing users to quickly swap pulleys based on driving conditions. The system includes a steel hub, which is pressed onto the supercharger using the stock pulley tool. This hub facilitates easy pulley changes with an Allen wrench, making it ideal for switching between a street-oriented pulley and a smaller one for track use or when running higher octane fuel. The system comes complete with the hub, your chosen pulley, five stainless socket cap button screws, and a barbed retainer to replace the breather bolt.\n\nOur pulleys feature 8 ribs, but a 6-rib belt will still function correctly. The bolt torque specification for installation is 72 inch-pounds.\n\nThis modular pulley system is recommended for those planning future modifications to their vehicles. ZZPerformance offers various pulley sizes to match different modification levels, from street use to track-focused setups. For example, a 3.5\" pulley is recommended for 2001-2003 GTP\/GS models with a ZZP PCM, thermostat, colder plugs, bolt-in downpipe, and cold air intake. For 2004+ Grand Prix models, a 3.5\" pulley is recommended with 1.9 rockers, a thermostat, colder plugs, exhaust work, and a cold air intake. Smaller pulleys, such as the 3.3\" and below, require more significant modifications like cams, headers, or upgraded intercoolers.\n\nThis system fits the following vehicles: Pontiac Grand Prix GTP or 06+ GT, Buick Regal GS, Pontiac Bonneville SSEi, 04+ Impala SS, and 04+ Monte Carlo SS.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52664173035832,"sku":"ZZ-MPS38-3.4-BLK","price":99.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687545767.jpg?v=1784334675","url":"https:\/\/store.motormia.co\/products\/3800-modular-pulley-system","provider":"MOTORMIA","version":"1.0","type":"link"}
