{"product_id":"hellraiser-2-72-pulley-kit","title":"HellRaiser 2.72\" Pulley Kit","description":"Developed by Litens High Performance, the same company that produces OEM pulleys for various Hellcat-powered vehicles, this kit features a 2.72-inch diameter pulley. It incorporates the crucial internal decoupling and isolating assembly found in stock pulleys, which helps to reduce stress and associated wear on the supercharger's bearings and rotors.\n\nThis kit is designed to increase boost pressure, delivering approximately 16 PSI on Hellcat and Trackhawk superchargers, and up to 20 PSI on Demon and Redeye superchargers at sea level. Compared to the stock 3.43-inch pulleys, the HellRaiser offers a significant increase in performance potential. The kit includes the 2.72\" Litens Automotive Supercharger Pulley, an End Cap (dust\/tamper shield), a 17mm Install Tool, and a Gates HD Belt.\n\nIt is important to note that the installation of this pulley kit requires supporting modifications, specifically larger fuel injectors and custom engine tuning. Modern Muscle Performance, LLC. advises that while pinning of the crankshaft pulley is not believed to be required, they assume no liability for any damage that may occur due to unpinned cranks. Additionally, buyers are reminded to check local and State laws for emissions compliance before purchasing this product.","brand":"Litens Automotive","offers":[{"title":"Default Title","offer_id":52686636908856,"sku":"920666K","price":673.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659703755.jpg?v=1784875518","url":"https:\/\/store.motormia.co\/products\/hellraiser-2-72-pulley-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
