If your Jeep has a winch, air compressor, aftermarket lights, or stereo, you're probably taxing your charging system beyond OEM specifications. Our Alliance 4x4 Alternators provide a 50% increase at 240 Amps over the OEM 160 Amp Alternator. Our Alternator can handle the extra load without breaking a sweat. It's an easy, drop-in upgrade with simple hand tools, and comes with a 2 Year/Unlimited Mile Warranty.
Note: This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension, that can be purchased from your local autoparts store. As with any high output hairpin unit for this application, minor grinding is required on the inside radius of the factory alternator bracket for clearance.
