2007-2014 GM Truck/SUV 5.3L Whipple Supercharger Kit

2007-2014 GM 5.3L TRUCK / SUV
WHIPPLE SUPERCHARGER KIT

Few upgrades transform a truck or SUV 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 5.3L truck and SUV 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-1111 system for 2007-2013 GM 5.3L truck applications and 2007-2014 GM 5.3L SUV applications, delivering substantial horsepower and torque gains in a proven bolt-on package.

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 up to 225 horsepower and 215 lb-ft over stock on 91-octane fuel. The result is a stronger, more responsive 5.3L platform with the kind of usable power truck and SUV owners can feel immediately.

To support that performance, the package uses a massive bar-and-plate air-to-water intercooler, oversized heat exchanger, electric intercooler pump, and complete low-temp cooling circuit to help maintain lower air charge temperatures under load. The system also includes high-flow fuel injectors, HP Tuners RTD support, high-flow S&B air filter, Whipple air inlet duct, and the hardware needed for a complete installation.

When used as intended, the result is a serious Whipple-powered GM truck or SUV with improved drivability, stronger towing performance, and repeatable power in a 50-state legal package for qualifying applications.
