Product Details

The Eaton Gen VI 2300 TVS rotating assembly at the heart of this Edelbrock E-Force Supercharger system features a four-lobe design with 160 degrees of twist. This advanced design is key to achieving maximum airflow while keeping temperature rise to a minimum, contributing to quiet operation and excellent drivability for your 2003-2006 Chevrolet Silverado 1500 or 2007 Classic model.

This supercharger system is designed to boost the performance of your 4.8L, 5.3L, or 6.0L Gen III engine. For the 6.0L, Edelbrock estimates rear-wheel gains to 364 horsepower and 397 ft-lbs of torque when paired with a proper Edelbrock tune. For the 4.8L and 5.3L engines, expect increases to around 339 horsepower and 359 ft-lbs of torque at the rear wheels, also assuming an Edelbrock tune. It's important to note that this kit is sold without a handheld programmer, meaning custom tuning by the customer is required for optimal performance and emissions compliance.

Edelbrock has also integrated a bypass valve to reduce parasitic loss when you're not demanding full power, which can help improve fuel economy. The unique inlet configuration creates a shorter, less restrictive path for airflow, eliminating the need for a jack-shaft. To keep intake air temperatures down, a high-capacity air-to-water intercooler and low-temperature heat exchanger are included. This system is a substantial upgrade for those looking to significantly enhance their truck's power output.
