Brand new in the box mechman alternator P/N: 11243240 will fit 07-11, 3.8L engines. This one is rated at 147a at idle and 245a at 1800rpm. It is brand new in the box never been installed. These are $400 brand new and I will include 6' of 0 gauge black and 6' of 0 gauge red cable to make the appropriate new cables for the power that this can output. You DO NOT want to use your stock cables. This is great for someone who actually uses their winch or other high draw accessories.
