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 percent Brand New, No Core!
  • Fits: 2011-2019 GM 6.6L Duramax

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 either alternator.

XDP does not recommend the installation of (2) of these units on the same truck as overcharging may occur.

Cheap and worth it.
Size: 42W x 28L, Color: Black
Cheap and looks nice, tbh. I orders a 42wx28l and it was a nice fit. I order 28L so the seam usually can sit above my ankle or shoe but It was a bit longer compared to my other various pants at 28L, it felt more like a 30L. I’ve noticed the waist seems to fit a bit larger than I’m used to but overall a nice fit and material. One thing worth mentioning is the stitching at the bottom seems a bit loose.

High Quality Cotton, Well Cut
Size: 36W x 32L, Color: Black
I was pretty impressed with the high quality of these pants. Remove the Amazon label and you wouldn't think twice if it had a Gap, Banana Repblic or Levi's instead. They are well cut and well stitched. I ordered black and the color looks great too. Fits to size.

Great fit
Size: 36W x 32L, Color: Dark Khaki
My boys love these pants. College son prefers them when he is golfing. They fit well and are comfortable. He usually wears southern tide brand which are extremely pricey. So happy to have found these. Already ordered in multiple colors. They are nice and thin for Florida weather

Great Pants
Size: 31W x 28L, Color: Black
I wasn’t sure what to expect when I ordered these, but I’m really glad I did. The pants look even better in person than in the photos , the color is accurate and the fabric has a nice, quality feel to it. The fit is spot on. I bought it in 3-4 colors.

Decent for the price, but inconsistent quality
Size: 33W x 29L, Color: Dark Grey
Quality can be hit or miss. I ordered several pairs of the same "model" and fit is inconsistent. One pair fit great, another pair of a different color felt 3 sizes too small. Leg width can be slightly different from pant to pant or the legs have a bit of a "twist" sewn in them. For the price, I'm not expecting perfection.
