Edelbrock Supercharger Stage 1 - Street Kit 2003-2006 GM Gmt800 Trucks 4 8 5 3 6 0L w/ Tuner - 1577

The Edelbrock supercharger Stage 1 Street system part #1577 is for 2003-06 Silverado and Sierra 1500 and 2007 Sierra Classic vehicles. This supercharger system works with the 6.0L, 4.8L and 5.3L Gen III engines and increases the performance of the 6.0L engine to 348 horsepower and 381 ft-lbs at the rear wheels, 4.8L engine to 339 horsepower and 359 ft-lbs of torque at the rear wheels and the 5.3L engine to 345 horsepower and 381 ft-lbs of torque at the rear wheels. The core of this system is the Eaton Gen VI 2300 TVS 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. The Edelbrock #1577 system is 50-state emissions legal. The supplied tune is intended for completely stock vehicles with the exception of a cat-back exhaust.

About Edelbrock

Edelbrock was founded in 1938 by Vic Edelbrock Sr. in Los Angeles, California. Initially, the company focused on producing performance parts, with Vic's first major success being a high-performance intake manifold designed for flathead V8 engines. This innovation helped enhance engine efficiency and performance, laying the foundation for the company's reputation in the automotive aftermarket. Vic's love for racing also played a significant role in the early development of Edelbrock, as he designed parts to improve the speed and power of his own cars.

By the 1950s and 1960s, Edelbrock began to expand its product offerings, moving beyond intake manifolds to include carburetors, camshafts, and other components essential for performance cars. The company gained recognition in the burgeoning hot rod and drag racing scenes, particularly in California, where racing culture was rapidly growing. Edelbrock's products were highly regarded for their quality and performance, earning the company a loyal following among car enthusiasts and racers.

During the 1970s, the company solidified its position as a leader in the performance parts industry. With Vic Edelbrock Jr. joining the business, Edelbrock expanded its reach beyond racing into the street performance market, offering a variety of parts for muscle cars and street machines. The Edelbrock carburetor became a go-to choice for enthusiasts looking to boost engine performance, and the company continued to innovate, expanding its product line to meet the growing demands of car enthusiasts.

The 1980s and 1990s marked a period of continued growth for Edelbrock as the company advanced with cutting-edge technologies, such as the introduction of electronic fuel injection (EFI) systems and aluminum cylinder heads. Edelbrock was a key player in motorsports, supporting events in NASCAR, NHRA drag racing, and circle track racing. The company's emphasis on technological innovation helped it remain at the forefront of the performance parts industry.

In the 2000s, Edelbrock adapted to modern advancements in manufacturing, utilizing CNC-machining and computer modeling for greater precision in its products. The company also expanded its portfolio, delving into areas like superchargers, performance exhaust systems, and automotive electronics. As the market shifted, Edelbrock continued to develop high-performance parts to meet the needs of both racers and car enthusiasts.

In 2020, Edelbrock was acquired by Icahn Enterprises, a holding company controlled by investor Carl Icahn. Despite this change in ownership, Edelbrock has maintained its legacy as a trusted brand in automotive performance. The company continues to innovate with new products and technologies, ensuring that it remains a leader in the automotive aftermarket space.

Today, Edelbrock is a globally recognized name in the automotive performance industry. The company’s long history of innovation, dedication to quality, and commitment to performance has earned it a loyal customer base that includes racing professionals, car builders, and hobbyists alike. From its humble beginnings to its current standing as a giant in the performance parts world, Edelbrock’s legacy of excellence continues to shape the automotive landscape.
