RIPP Supercharger Jeep JK Wrangler 3.8L 07-11. I recently installed a 6.2l V8 in Jeep and no longer need the supercharger. Comes with supercharger, mounting brackets, belt pulleys, air cleaner, fuel rail & injectors and Diablo "unlocked/never used" programmer. The supercharger makes a noticeable difference when running 35" or bigger tires. Easy to install. Instruction included. There are also a bunch of YouTube videos that show the process.
