The Edelbrock Supercharger System part #15356 is designed for your 2015 6.4L HEMI Jeep Grand Cherokee SRT. The part #15356 kit makes an excellent amount of horsepower and torque. 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 R2650 Supercharger rotating assembly with a four-lobe design with 170 degrees of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. This supercharger features our DUAL PASS, 3 CORE (DP-3C) intercooler system. 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.
