2018-2021 Jeep Grand Cherokee 6.4L Gen 6 3.0L Whipple Supercharger Kit

The Whipple Gen 6 3.0L Supercharger Kit delivers modern twin-screw performance to the 2018-2021 Jeep Grand Cherokee 6.4L HEMI with the airflow, cooling capacity, and complete-system engineering expected from Whipple. Built as a complete bolt-on package, this system delivers instant boost, strong mid-range acceleration, and a broad torque curve that makes the 6.4L platform feel stronger throughout the RPM range.

POWER: With 93 octane fuel, the Whipple Gen 6 system is rated for up to 710 HP and 650 LB-FT of torque, with dyno-proven gains of up to 180 rear-wheel horsepower. That gives the Grand Cherokee 6.4L the immediate throttle response, strong acceleration, and flat usable torque curve expected from a positive displacement Whipple supercharger system.

At the center of the package is the Gen 6 3.0L twin-screw supercharger with an oversized 112mm inlet designed to move more air with less restriction. Combined with Whipple's efficient rotor technology and Drag Pak-proven development, the result is strong throttle response, instant boost, and repeatable performance from idle to redline.

Cooling is a major part of the Whipple advantage. The patented dual-core, dual-pass intercooler system is designed to control charge air temperatures and support consistent performance under load. The complete package also includes the supporting heat exchanger, intercooler pump, and associated hardware needed for a true bolt-on Whipple system rather than a partial airflow upgrade.

This system is engineered as a complete bolt-on package with no internal engine modifications required. It includes billet fuel rails, high-flow injectors, plug-and-play wiring, OEM-style quick-connect fittings, and the hardware needed for a clean factory-style installation. The 6-rib belt drive with adjustable idler supports reliable operation while also allowing fast pulley changes.

For 2018-2021 applications, the package includes HP Tuners RTD support along with PCM unlock support and security bypass support for proper calibration access. That gives the Grand Cherokee 6.4L platform the tuning and flashing support needed for a complete Whipple system.

Since 1987, Whipple Superchargers has led the twin-screw supercharger market with systems built around real airflow, real efficiency, and real-world performance. Whipple supercharger systems are designed, manufactured, and assembled in Fresno, California, USA.
