{"product_id":"performance-pulley-1","title":"Performance Pulley","description":"The RalcoRZ performance pulley is a precision-engineered underdrive crank pulley designed for 1986-1992 Toyota Supra vehicles equipped with the 3.0L DOHC 24V Turbo or Non-Turbo engine (JZA70\/7MGE\/7MGTE). By replacing the heavy factory crank pulley with this lightweight aluminum conversion, the engine experiences a reduction in rotating mass, which contributes to improved throttle response and measurable gains in horsepower and torque.\n\nThis pulley is machined from 6061 aluminum billet and hardened steel to ensure long-term reliability and performance. It is specifically designed as a crank-only installation. Please note that this product is intended exclusively for the 1986-1992 Toyota Supra; fitment for other models or configurations is not supported.","brand":"RalcoRZ","offers":[{"title":"Default Title","offer_id":52663427694904,"sku":"914864","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687393324.jpg?v=1784326813","url":"https:\/\/store.motormia.co\/products\/performance-pulley-1","provider":"MOTORMIA","version":"1.0","type":"link"}
