{"product_id":"hellcat-supercharger-pulley","title":"Hellcat Supercharger Pulley","description":"The Metco Motorsports Hellcat Supercharger Pulley is a precision-crafted performance upgrade for 2015 and newer Hellcat Challenger, Charger, Trackhawk, Demon, Redeye, Durango, and TRX models. This pulley system utilizes an interchangeable design, allowing for easy boost adjustments by simply swapping the outer pulley drive ring. The construction features a precision-machined stainless-steel hub, an interchangeable pulley drive ring, and a stock-appearing front cover, all anodized black and equipped with stainless steel or zinc-plated fasteners for durability and corrosion resistance.\n\nEach component is precisely machined on a state-of-the-art CNC lathe and perfectly balanced to ensure smooth operation at all engine speeds, thereby maximizing reliability.\n\nInstallation of this pulley is intended for professional installers only, as it requires disassembly of the upper portion of the supercharger and removal of the supercharger snout. Installation instructions are not provided. Significant modifications, including PCM calibration revisions, are necessary to accommodate the increased airflow resulting from the pulley change. While some installers have reported success with the 3.10\" and 3.20\" sizes without PCM tuning, it is always recommended to review the tune to confirm proper air\/fuel and timing calibrations for optimal reliability and longevity. The user assumes all risks associated with installation, and this modification may affect the vehicle's warranty.","brand":"Metco Motorsports","offers":[{"title":"Default Title","offer_id":52689066918200,"sku":"HCP3.20","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687381178.jpg?v=1784901248","url":"https:\/\/store.motormia.co\/products\/hellcat-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
