{"product_id":"billet-aluminum-crank-pulley-3","title":"Billet Aluminum Crank Pulley","description":"The COBB Tuning Lightweight Main Pulley is a performance-enhancing engine component crafted to reduce rotational mass. It is designed with a focus on maintaining factory specifications to ensure optimal vehicle function. Unlike some aftermarket pulleys, this COBB unit preserves the original pulley diameter, thereby preventing the under-driving of accessories which can lead to unwanted electrical behavior. Furthermore, it retains the stock drive belt surface, simplifying the installation process for owners of varying technical expertise. The design ensures a direct fit, minimizing the need for complex modifications.\n\nWith an overall weight of just 1.2 lbs, it contributes significantly to reducing the rotational mass of the engine's rotating assembly. This reduction can lead to quicker engine response and a slightly improved throttle reaction. The manufacturer rates the installation level as 2, indicating it is an easy job requiring only basic tools.","brand":"COBB Tuning","offers":[{"title":"Default Title","offer_id":52687433531704,"sku":"300102BK","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687893767.jpg?v=1784884002","url":"https:\/\/store.motormia.co\/products\/billet-aluminum-crank-pulley-3","provider":"MOTORMIA","version":"1.0","type":"link"}
