Joining Edelbrock's expanding line of supercharger systems are the Chevrolet & GMC 2015-2020 SUVs, 2014-2018 full size trucks, & 2019 Silverado LD & Sierra LDT (air box on right side) equipped with a Gen V 5.3L L83 engine (not a L8B hybrid). This is a true bolt-on performance kit that is emissions legal in all 50 states and produces an impressive 482 horsepower with 452 ft-lbs of torque at the rear wheel on 93-octane pump gas! Edelbrock supercharger Kit No. 15663 for Silverado, Sierra, Suburban, Tahoe and Yukon models equipped with a Gen V 5.3L V8 engine is a complete redesign of the previous kit featuring a manifold that now houses Eaton's R2650 TVS rotor assembly along with a high-capacity Dual Pass 3-core intercooler system. The new rotors have a 170-degree high-twist lobe design with bigger bearings and beefier timing gears for unparalleled efficiency and OEM-like reliability. Like other superchargers in the Edelbrock line, this system is designed to fit under the stock hood with no cutting or modifications required. A self-contained oiling system keeps maintenance to a minimum with a service interval of 100,000 miles. The significant increase in horsepower and torque comes with minimal loss in fuel economy thanks to the system's integrated bypass valve that mitigates parasitic power loss during normal driving conditions. This new Edelbrock supercharger kit requires no internal modifications to the engine. For higher power demands, the R2650 supercharger can support 1,000-plus horsepower at the flywheel with the right combination of parts. This kit includes everything required for a complete installation including a set of preformed hoses to simplify the process. A full-color manual provides clear step-by-step instructions for the installer. Comes finished in a durable black powder-coating that blends nicely into the engine compartment. All Edelbrock Supercharger Systems are designed and manufactured in the USA.
