{"product_id":"hellmax-pulley-kit","title":"HELLMAX Pulley Kit","description":"The SPE Motorsport HELLMAX Pulley Kit is engineered for the 2015+ 6.2 Hemi platform, specifically designed to enhance performance by increasing boost levels. This upgrade results in greater horsepower and torque output, making it a significant performance enhancement for compatible vehicles.\n\nConstructed with a focus on reducing rotational mass, the kit includes a lightweight titanium hub, which is highlighted as the lightest available supercharger hub on the market. The hardware is also made from titanium, with options for various anodized colors including black, blue, bronze, and green. SPE utilizes a proprietary CNC Convex Knurling Process (CKP) on their pulleys, which provides an optimal balance of belt grip and wear. This innovative machining process allows for varying grip under different belt loads, ensuring less belt wear during low-load conditions and more aggressive grip when boost demand increases. Unlike competitor's methods like laser etching, SPE's process ensures durability and consistent performance over time.\n\nThe kit includes the pulley itself, a titanium hub, titanium hardware, a blower shaft holding tool, and a custom hub socket for installation. SPE notes that other pulley sizes may require tuning, and larger pulleys may not require the CKP in certain applications due to sufficient grip. For those seeking maximum power, SPE Motorsport offers various options and guidance on pulley sizing, with each .100 smaller pulley size equating to approximately a 1 PSI increase, depending on altitude.","brand":"SPE Motorsport","offers":[{"title":"Default Title","offer_id":52866385969464,"sku":"SPE-H100120","price":509.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687688035.webp?v=1787906973","url":"https:\/\/store.motormia.co\/products\/hellmax-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
