The Edelbrock Supercharger System part #15380 delivers excellent horsepower and torque for your 2009-14 5.7L HEMI Dodge Ram Truck. This kit allows you to take our Stage 1 kit and get the custom tune you desire. Featuring a unique design with minimal components makes it possible to fit an Edelbrock supercharger under the stock hood. The core of each system is the Eaton Gen VI 2300 Supercharger rotating assembly with a four-lobe design with 160 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. We also designed our superchargers with an integrated bypass valve to help eliminate parasitic loss under light throttle, improving mileage potential. Our unique and efficient inlet configuration results in a shorter, less restrictive intake path for improved airflow, without the need for a jack-shaft. Keeping the air cool is a high-capacity air-to-water intercooler and low-temp heat exchanger. For safety, the Edelbrock-supplied program will retain the factory vehicle speed limiter setting. This kit is NOT supplied with a programmer. Supercharger systems without tuners are not eligible for supplemental warranty. Supercharger systems sold without tuners are only emissions legal when used with the correct Edelbrock program.
