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 to be installed for proper belt tension.
