{"product_id":"70mm-supercharger-pulley","title":"70mm Supercharger Pulley","description":"The VRP clutched supercharger pulley is a precision-engineered upgrade designed specifically for the Mercedes-Benz AMG M113k engine platform, including E55, SL55, CL55, S55, and CLS55 models from 2003-2006. By replacing the larger factory pulley—which typically measures 88mm-90mm—with this 70mm unit, owners can achieve significant increases in rear-wheel horsepower and torque through improved supercharger boost levels.\n\nThis high-performance component is built to reduce rotational mass, which assists in extending the lifespan of the supercharger assembly. It is the smallest size compatible with the factory blower, balancing performance gains with mechanical reliability. Note that a tune is strictly required with this pulley to ensure safe and efficient operation; the manufacturer recommends using full supporting modifications to maximize power potential.\n\nInstallation includes the pulley, clutch assembly, and magnet. Users should be aware that power results may vary based on individual vehicle setups and supporting modifications. Always consult professional installation guidelines for your specific M113k platform to ensure correct pulley alignment and integration with the vehicle's electronic systems.","brand":"Vrp","offers":[{"title":"Default Title","offer_id":52866539422008,"sku":"VRP-70MM-PULLEY","price":780.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687406501.png?v=1787909251","url":"https:\/\/store.motormia.co\/products\/70mm-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
