{"product_id":"76mm-clutched-supercharger-pulley","title":"76mm Clutched Supercharger Pulley","description":"The BenzUnited Parts 76mm Clutched Supercharger Pulley is engineered to unlock more horsepower and torque for Mercedes-Benz AMG models equipped with the M113K 5.4L V8 engine. This precision-machined upgrade features a 76mm diameter and a spring-loaded clutch hub design, which helps reduce parasitic drag, minimizes belt slip at idle, and extends the life of the belt and supercharger bearings.\n\nManufactured from Billet 6061-T6 Aluminum, this pulley is available in Anodized Black or Silver finishes. Its design focuses on reducing rotational mass to enhance supercharger longevity. The pulley assembly is sold as a standalone component; idler pulleys and belts are sold separately and may be required for proper installation and tension.\n\nThis upgrade has been tested to show gains of 50-55 rear-wheel horsepower and torque, while maintaining safe boost levels and supercharger RPM. It offers improved drivability without negatively impacting highway fuel economy. For optimal performance and to fully leverage the increased boost potential, ECU tuning is strongly recommended, along with potential supporting modifications such as an upgraded heat exchanger and a longer belt for proper tension.\n\nVehicle Fitment: This pulley is compatible with all Mercedes-Benz AMG models featuring the supercharged 5.4L V8 M113K engine, including the E55, SL55, CL55, S55, CLS55, and G55.","brand":"BenzUnited Parts","offers":[{"title":"Default Title","offer_id":52687119450424,"sku":"76mm-clutched-supercharger-pulley-for-mercedes-amg-m113k-e55-sl55","price":695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662153252.jpg?v=1784880535","url":"https:\/\/store.motormia.co\/products\/76mm-clutched-supercharger-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
