{"product_id":"nst-crankshaft-pulley-kit","title":"NST Crankshaft Pulley Kit","description":"The NonStopTuning Nissan 370Z \u0026amp; Infiniti G37 VQ37HR Pulley Kit is engineered to boost horsepower by significantly reducing weight and underdriving accessories.\n\nEach pulley in the NST kit is precision CNC machined from 6061-T6 aircraft-quality aluminum, ensuring tight machining and balance tolerances. The crank pulley weighs approximately 19 ounces (550 grams), while the alternator pulley is a mere 2.5 ounces (75 grams), representing a 70-75% weight reduction compared to OEM parts. For enhanced longevity and strength, all NST pulleys undergo a hard anodization process. They are available in multiple colors to customize your engine bay's appearance.\n\nInstallation of this pulley kit requires the Gates K070786 serpentine belt, which can be purchased separately. The manufacturer highlights that their pulleys are stronger and more durable than OEM cast iron components, as the anodized aluminum will not corrode. Additionally, NST crank pulleys feature oil sleeves where necessary and proper timing marks, features often absent in competing products.\n\nThe weight reduction and smoother operation provided by these pulleys contribute to improved throttle response and potentially better fuel economy. NonStopTuning also notes their commitment to ongoing research and development, offering a wider selection of pulleys than many competitors.","brand":"Nonstop Tuning","offers":[{"title":"Default Title","offer_id":52687915254072,"sku":"NST13710K","price":128.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664706324.jpg?v=1784887304","url":"https:\/\/store.motormia.co\/products\/nst-crankshaft-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
