Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

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.

Warranty:
Products manufactured by XDP carry a 1-Year warranty against defects in materials and craftsmanship. The Warranty is Limited to one (1) year from the date of sale and limited solely to the parts contained within the product's kit.
