Description

Enhance the charging system in your 2011-2019 GM 6.6L Duramax with the XDP Wrinkle Black HD High Output Alternator XD350. While many Duramax owners upgrade their truck for performance, the charging system is often overlooked until there is an issue. Aftermarket accessories such as off-road lights, aftermarket horn kits, on-board air compressors, snowplows, stereo equipment and other electronics will overload your factory charging system and demand more than what the factory alternator can provide. 

The XDP HD Series High Output Alternator increases the output of your factory charging system giving you the ability to reliably run your high-draw electronics while alleviating the strain on your charging system. The XD350 features an OE style decoupler pulley that helps synchronize the serpentine belt to improve efficiency, while also reducing the noise/vibration/harshness (NVH) and increasing accessory drive component life. Each XDP HD Alternator comes with an ultra-durable wrinkle black coating and is pre-tested for an easy bolt-on installation.  

Features: 
  • 245 Amp Output
  • Bolt-On Upgrade
  • OEM Style Decoupler Pulley
  • 100% Brand New, No Core! 
Application Note:
This alternator fits on trucks equipped with dual and single alternator applications.
In dual alternator applications, this alternator can be used as a replacement for both alternators.

Warranty Info:

Looks sharp and works extremely well for high electrical demands like plowing!

The old alternator couldn't keep up with the V plow and putting a second alternator on would've cost too much since the harness would have to be spliced or a new one installed to accommodate two alternators. This one mounted up perfectly and all i needed to replace was the charging cable since the old one is a 4 gauge and this alternator required a 2 gauge. A ground wire was also needed but that was simple to attach and then attach to the block.
