{"product_id":"oem-diameter-performance-pulley-set","title":"OEM-Diameter Performance Pulley Set","description":"These pulleys maintain OEM diameter, ensuring they neither underdrive nor overdrive essential accessories. This design facilitates enhanced throttle response and noticeable gains in horsepower and torque, making them suitable for naturally aspirated, turbocharged, or supercharged configurations.\n\nConstructed from 6061-T6 aircraft-quality aluminum, the NST pulleys offer a significant weight reduction of 70-75% compared to OEM components. The Crank, Alternator, and Water Pump pulleys feature a durable hard-anodized finish for exceptional longevity, with a choice of colors available. For superior strength and wear resistance, the Idler and Tensioner pulleys are exclusively hard-anodized, resulting in a unique graphite gray color and maximum durability.\n\nEach kit is CNC-machined to tight tolerances and balanced for smooth operation. Unlike some competitors, NST crank pulleys include necessary oil sleeves and feature proper timing marks for easier installation and more accurate engine tuning.","brand":"NST (NonStopTuning)","offers":[{"title":"Default Title","offer_id":52663170203960,"sku":"NST08600K","price":268.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687519600.jpg?v=1784324487","url":"https:\/\/store.motormia.co\/products\/oem-diameter-performance-pulley-set","provider":"MOTORMIA","version":"1.0","type":"link"}
