        This says up to 2011. Will this fit my 2014 Wrangler JKU Sport?

        • Hello! Those numbers are accurate, and this only fits up to 2011 Wranglers.

        Will this alternator produce enough amps to support duel batteries ?

        • The PA Performance Alternator will produce a maximum of 160 Amps, which will be more than adequate for a dual battery setup.

        Can you tell me if this part will bolt into the 07 2.8ltr diesel JKU Wrangler?

        • The PA Performance Alternator is designed specifically for the 3.8L and would not work with the 2.8L diesel.

            Don’t know if I got a faulty one, but the chrome part where the belt touches/goes does not spin. Looking into how the return process would work since I threw away the packaging.

            Fantastic Alternator

            I purchased this alternator for my 2016 Jeep Wrangler Sport and so far, it has been outstanding. This product has no trouble supplying my 15 inch dual light bar, as well as my 12 inch dual bar. The build quality is outstanding and would definitely recommend this alternator to anyone using additional lights, or anything else needed additional power.
