Don't just replace the failing alternator in your 2001-2007 GM 6.6L Duramax, upgrade it with the XDP Direct Replacement High Output 220 AMP Alternator XD224. The XDP Direct Replacement Alternators are the perfect option for the Duramax owner that upgraded their truck and wants more than a remanufactured parts store unit. 

Common performance upgrades like plows, on-board air systems, horn kits, and lighting upgrades can max out the capabilities of your charging system. The XD224 is designed to increase reliability and output of your charging system to alleviate the strain of aftermarket upgrades. With a 220 Amp output, this alternator almost doubles the factory output. This gives you the ability to get the most out of your charging system whether you're out plowing snow, or at an event showing off stereo system upgrades.

Ordered on a Friday morning and had it at my house next day in the am. Shipping was absolutely amazing and it was free!! Product was packaged very well! Installed in mins and looks amazing and definitely better than the stock 130amp. Definitely recommend for anyone looking to replace a stock one or needs to upgrade to a bigger one!!
Great alternator order #1138988
(TX) | April 30th, 2020
Great fit. Easy install. I also did the big three 0 gauge power to both batteries and grounds from both batteries to engine and frame. With 3 - 330w, 1 - 2500w amps, 2 -24", 1 - 52" light bars and 2 compressors on board I am running at a constant 14.4v. I have never ran that high, even with the mean green. The mean green lasted about 14 months. So the only question at this point will be longevity, fingers crossed.
Great Quality & Easy Installation

The alternator is really high quality, looks good (if that matters to you) and functions better than stock. Super simple to install. No complaints here and highly recommend it as a stock replacement part.
