Description

Enhance the charging system in your 2011-2019 GM 6.6L Duramax with the XDP HD High Output Alternator (New) Wrinkle Black 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 includes the results of pre-testing for an easy bolt-on installation.  

Features: 
  • Bolt-On Upgrade
  • 245 Amp Peak Output
  • 150 Amp Output At Idle
  • 100% Brand New, No Core!
  • OEM Style Decoupler Pulley
  • Pre-Tested With Included Results
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:

Awesome alternator

The price is the price, once you get over that you’ll be thoroughly pleased with this alternator. Delivers what it promises, and great charging at idle. Between modern truck electronics demand with amps and onboard air this is the part you didn’t know you needed. Order #2121871

If you need that extra amperage to power all your aftermarket electronics this is for you!!

Perfect fit, definitely follow instructions to upgrade to 2 AWG wiring, no more issues with audio system cutting out due to power draw! Excellent customer service as well!!
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.
