Whipple Supercharger 2004-2006 GM Truck 4.8L Kit

2004-2006 GM TRUCK 4.8L
WHIPPLE SUPERCHARGER KIT

Few upgrades transform a truck like a properly engineered twin-screw supercharger system. The added low-end torque, sharper throttle response, and stronger pull through the RPM range completely change how the vehicle feels whether it is used for daily driving, towing, or hauling. That is exactly what the Whipple system delivers for GM's 4.8L truck platform.

Whipple Superchargers has been at the forefront of twin-screw supercharging technology since 1987, developing some of the most powerful and efficient forced-induction systems in the industry. That experience carries into the Whipple WK-1100 system for 2004-2006 GM truck applications equipped with the 4.8L engine, delivering substantial horsepower gains in a proven bolt-on package built for strong street manners, dependable drivability, and serious usable power.

At the center of the system is Whipple's W140AX 2.3L twin-screw supercharger, engineered for strong airflow, immediate boost response, and broad torque delivery. On qualifying applications, the system is capable of producing gains of over 160 horsepower on 91-octane fuel with 7-8 psi of boost. The result is a stronger, more responsive 4.8L platform with the kind of instant torque and broad power curve that truck owners can feel immediately.

To support that performance, the package uses a massive air-to-water intercooler to help reduce air charge temperatures under load and maintain more consistent performance in demanding driving conditions. The system also includes high-flow fuel injectors, an aluminum high-flow intake manifold, HP Tuners RTD support, and the hardware needed for a complete installation.

When used as intended, the result is a serious Whipple-powered GM truck with improved drivability, stronger towing performance, and repeatable power in a clean, well-integrated package.
