This addition to Edelbrock's expanding line of superchargers is highlighted by significant improvements for Chevrolet/GMC/Cadillac 2015-2020 SUVs and 2014-2018 full size trucks with the GM 6.2L L86 V8 engine. This is a bolt-on performance kit that is emissions legal in all 50 states and produces 576 horsepower with 537 ft-lbs of torque at the rear wheel. This is the perfect power adder whether you plan to tow a trailer, haul heavier loads, or you just want to feel your truck/SUV come to life without sacrificing daily drivability! The new Edelbrock supercharger Kit No. 15664 for Chevy/GMC/Cadillac trucks and SUVs is a complete redesign of our No. 1565 and No. 1566 kits featuring an all-new manifold with R2650 TVS rotors for unparalleled efficiency and reliability. The Edelbrock supercharger Kit for the 6.2L V8 fits under the stock hood with absolutely no cutting or modifications required. And if you're concerned about the effect on MPG, the increase in power comes with little to no loss in fuel economy thanks to the supercharger's integrated bypass valve that mitigates parasitic power loss during normal driving. This new kit is a true bolt-on that requires no additional modifications to the stock 6.2L engine. For those who want more power, the R2650 supercharger can support more than 1,000 horsepower at the flywheel with the right combination of parts. This Edelbrock supercharger features a self-contained lubrication system with a 100,000-mile service interval with a high-capacity Dual-Pass 3-Core (DP3C) integrated intercooler and comes finished in a durable black powder-coating that blends nicely with the engine. Each kit includes a complete set of preformed hoses, hardware and a full-color manual that provides clear step-by-step instructions for ease of installation. This system is designed and manufactured in the USA.
