A twin screw supercharger kit for the 5.3L. The 3.0L blower sits where the factory intake manifold was and is driven off the belt. Because it is a positive displacement design, it makes boost from low rpm rather than building it as revs climb.
why this one — Same kit and the same claimed 595 horsepower and 570 lb-ft as the Global B version, $500 cheaper, built for the 2019 through 2022 trucks that use the older Global A computer. It needs 91 octane or better and HP Tuners calibration support. The two Whipple kits are not interchangeable, so match your model year before you order.
Whipple's own product page states "up to 595 HP and 570 lb-ft of torque on 93 octane" - a TOTAL output figure, not an isolated gain over stock.
CARB EO D-231-146 (50-state legal), per manufacturer.
