2014-2018 GM 2500HD Truck 6.0L Whipple Supercharger Kit

The Whipple WK-1114 Supercharger Kit is designed for 2014-2018 GM 2500HD truck applications equipped with the 6.0L engine. Built around the Whipple W140AX 2.3L twin-screw supercharger, this system delivers strong horsepower and torque in a proven bolt-on package designed for heavy-duty truck performance, towing power, and street use.

On tested applications, the system delivered up to 397 horsepower and 414 lb-ft of torque. The W140AX design supports excellent airflow and efficiency, while the massive air-to-water intercooler helps reduce air charge temperatures for more consistent performance under load. With 7-8 psi of boost on 91-octane fuel, the system is designed to deliver strong low-end torque and improved throttle response for demanding truck applications.

This system includes the major components needed for installation, including the 2.3L supercharger, aluminum high-flow intake manifold, fitted hoses, required wiring connections, and calibration support. On stock vehicles or trucks equipped with a cat-back exhaust only, the included calibration provides a straightforward bolt-on solution.
