Description
Whipple Gen 6 3.0L Supercharger Kit — Jeep Grand Cherokee SRT 6.4L (2015–2017)
The Whipple Gen 6 3.0L twin-screw supercharger is the biggest bolt-on power upgrade for the 2015–2017 Grand Cherokee SRT (often still called the SRT8). It delivers instant boost and a broad, flat torque curve from the 6.4L HEMI, with no internal engine modifications needed. It’s the same supercharger technology Dodge uses in its factory Drag Pak race cars.
MAP is the UK’s only authorised installing Whipple dealer. We supply and fit the kit at our West Yorkshire workshop, calibrate it on our in-house dyno, and ship kits worldwide.
- Fits: 2015–2017 Jeep Grand Cherokee SRT, 6.4L HEMI V8 (right-hand drive and left-hand drive)
- Supercharger: Whipple Gen 6 3.0L twin-screw, front-entry, with 112mm Crusher™ inlet
- Whipple part number: WK-3131-30
ECU unlock: we take care of it
This kit needs the car’s engine computer (PCM) unlocked so it can run the Whipple calibration. When MAP installs your kit, we take care of the ECU unlock as part of the job, so there’s nothing extra for you to arrange.
Buying the kit to fit yourself? Whipple includes the HP Tuners unlock code with every kit, and the PCM is sent to HP Tuners for the unlock service.
