The 2011-2014 WK2 Jeep Grand Cherokee is a great combination of American know-how and European flair. The 5.7 does a good job power wise, but we can always use a little more. When tested on our dyno it produced 280 Rear Wheel HP (whp) which in our opinion is de-tuned and capable of so much more. With the RIPP Supercharger system installed we netted 420whp (AWD) at just 6psi on an otherwise stock vehicle. That's an incredible 150whp gain to all four wheels! That will give you weekend warriors enough power to tow anything you want with ease. No more struggling over those long grades. No more judging distance to maintain pulling speed and best of all no more running the engine up is high RPMs. The RIPP Supercharger system will give you the power you need when you need it. That's right, if hot-rodding is what you're looking for then consider the numbers. 420whp at all four wheels. We advertise real-world HP. To put it in perspective, 420whp is more wheel HP than a stock 2014 392 V8 SRT Jeep, in fact that's more HP even if that 392 had full exhaust headers, cat-back high performance exhaust, a cold air intake and a custom performance tune. So go a head, pull up to that light and let it RIPP, you'll catch them sleeping. RIPP Supercharger Systems come complete with everything you or your installer needs to get through the very easy 5-6hour install. No need to keep shopping after you buy our system like our competitors. Check out the long list of quality parts below, you'll be hard pressed to find anything you won't like.
