Give your dodge ram truck more towing power with our new E-Force Supercharger. E-Force supercharger systems are the most efficient designs on the market and will deliver an impressive 421 rear wheel horsepower and 441 ft-lbs. of torque for the popular Dodge 5.7L HEMI engine. This complete supercharger system provides maximum flow, minimum temperature rise, quiet operation and reliability only the Edelbrock name can guarantee. It features minimum air restriction in and out of the supercharger for optimal flow and performance. The individual 7" long intake runners allow for maximum low end torque for towing and off-road applications while maintaining great daily driving manners. * For 2014-Later Dodge Ram Supercharger Systems, Tunes are only AVAILABLE for 8-Speed Applications. * ALL 2015-Later Dodge Ram Supercharger Systems WILL REQUIRE the ECM to be sent in for modification... NO HANDHELD PROGRAMMER INCLUDED. This is an 8-10 day process/waiting period from the time they are received! * Supercharger systems without tunes are not eligible for supplemental warranty. Supercharger systems sold without tunes are only emissions legal when used with the correct Edelbrock tune, which can be downloaded on the supercharger tech support. Edelbrock Carb E.O. D-215-85
