Whipple Supercharger Kit Gen 6 3.0L (2015–2017 Jeep SRT8 6.4L)
Overview
The Whipple Gen 6 3.0L Supercharger Kit for the 2015–2017 Jeep Grand Cherokee SRT8 6.4L is the most powerful and technologically advanced bolt-on supercharger system ever offered for the Hemi platform. Built on over three decades of Whipple twin-screw innovation, this system delivers instant boost, massive torque, and race-proven durability—while remaining fully emissions compliant.
At the core is Whipple’s Gen 6 3.0L twin-screw supercharger with an integrated Crusher™ 112mm high-flow inlet. Combined with a dual-core, dual-pass intercooler system featuring massive bar-and-plate coolers, this setup provides industry-leading airflow and cooling efficiency for consistent, repeatable performance.
Race-Proven Gen 6 Technology
This system utilizes the same core technology trusted in the Dodge Drag Pak program, delivering unmatched efficiency from idle to redline. The Gen 6 supercharger features all-new bearings, gears, rotors, and housing, along with a 3x4 rotor combination, optimized inlet and discharge ports, and a 285-degree helix for superior airflow and reduced heat.
The result is neck-snapping low-end torque, relentless midrange pull, and strong top-end horsepower—without sacrificing drivability.
Performance Highlights
- Most powerful supercharger system available for the 6.4L Hemi
- Gen 6 3.0L Whipple twin-screw supercharger with 112mm Crusher™ inlet

Advanced Cooling & Airflow Control
Whipple’s patented dual intercooler core, dual-pass design delivers lower air charge temperatures than any other positive displacement supercharger option on the market. The massive air-to-water aluminum bar-plate intercoolers are paired with an oversized heat exchanger and a high-flow intercooler pump to ensure rapid recovery times under aggressive driving.
An oversized intercooled air-bypass system further reduces burst knock by preventing the recirculation of hot air—an area where many competing systems fall short.
Complete, Turnkey Fuel & Electronics Package
This kit includes Hellcat high-flow fuel injectors, billet fuel rails, and a fuel pump voltage booster, providing the fueling capacity needed for safe, reliable power. Plug-and-play wiring with OEM-style connectors ensures a clean, factory-quality installation.
A flash tool is included, allowing you to read and erase codes and perform advanced datalogging for tuning flexibility.
Installation & Expandability
No internal engine modifications are required, and once installed, the system maintains a factory-installed appearance. The proven 6-rib belt system with adjustable idler supports easy belt changes and multiple pulley configurations, including 3-minute pulley swaps.
